They contain information on procedures for safe•Installation•Commissioning and•MaintenanceThe safety information relating to the handling and use of the brake are summarised in a separatechapter.Before fitting the brake, it is in your own interest to familiarise yourself with the information contained in these instructions and the potential hazards relating to the use of the brake and to observe theapplicable safety rules and regulations in particular.... are intended for:•Fitters•Mechanics•Brake operatorsThese persons must be experienced in the use of electromagnetic brakes and have the necessary training.... uses the following symbols:∆Safety information is emphasised by a bright triangle•indicates enumerations-accompanies working steps carried out by youGeneral information on the productDescriptionSeawater-proof electromagnetic double-face spring-pressure operated brakes (SFB) and holding brakes (SFB-H) are safety brakes that are applied mechanically when the current is disconnected. This ensures that the brake still operates in the event of a power failure. Both types of brake are designed for dry-running operation, must only be operated in a safe condition and fitted, commissioned, operated and maintained only by specially trained installation personnel.Brakes with a rated voltage from 75V DC (low-voltage directive) carry the CE mark.SFBSFB series brakes are suitable for dynamic and static braking with minimum friction lining wear.SFB-HSFB-H series brakes are used only as holding brakes with emergency braking characteristics. The number of springs is increased compared to the normal brake, the maximum airgap reduced and wear with dynamic braking greater.Use for the intended purposeSFB and SFB-H series brakes are used for braking electric motors, e.g. on ships, drilling rigs, crane systems, in rolling mills and steel works, mining, transport and cable railways. Use for any other than the intended purpose is considered improper and not for the intended purpose. If there is any doubt that the intended application of the brake may not for the intended purpose, please consult PINTSCH BAMAG.Drive technology3Drive technology4Safety informationThe safety information provided here is of a general nature. Special safety information is provided at the beginning of a chapter or specific point in the text. Observing all safety information will help prevent accidents and damage to the brake.Safety rules and regulations must also be observed under the pressure of time.Accidents cannot be reversed.∆ Electromagnetic fieldsThe brake is not screened. In the immediate vicinity of the brake, electromagnetic fields can be produced, the strength of which depends on the site of the brake. The user must ensure compliance with the requirements of DIN VDE 0848, part 4, “Safety relating to electromagnetic fields in the range 0 Hz-30 kHz”.∆ Pacemakers or implantsPersons with pacemakers or implants must avoid the area of electromagnetic brakes in any event. The strong electromagnetic fields pose a danger to life!∆ Protective barriersMark out a working area of sufficient size around the brake. Cordon off points allowing public access with protective barriers around the working area of the brake.∆ Safety distanceA safety distance should be maintained to all hazardous zones to ensure safety of personnel and prevention of damage to the brake.∆ Avoid negligent behaviourRefrain from any actions that could affect the safety of the brake.∆ Do not dismantle the brake completelyThe brake may only be dismantled to the extent specified in the operating instructions. Any dismantling of the assemblies over and beyond the extent specified is forbidden.∆ Do not place or leave anything lying around in this areaBecause of the electromagnetic fields, no objects must be placed or left lying around inthe area of the brake. This applies in particular to metal objects.Safety informationDrive technology 5∆ Do not store any objects in this areaDo not store any flammable objects in the immediate vicinity of the brake.∆ Work with careBefore carrying out any work on the brake, measures must be taken against any dangers to the life and health of persons and damage to the brake:• Only closed shoes in a perfect condition must be worn. Open sandals, damaged or unsuitable shoes must not be worn.• Closed, tight-fitting working clothes must be worn. Wide work jackets and wide sleeves can be dangerous.• Long hair must be tied back.Work should only be carried out on the brake when:• All dangerous movements have stopped• Accidental and unexpected operation of the brake is made impossible by suitable measures • If the brake is loaded, other safety devices provide a braking and holding function.∆ Danger of crushingWhen working on the brake, heavy tools are used. Particular attention should therefore be paid to possible crushing points when:• Using tools• Fitting and removing the brake, accessories or spare parts • Unbolting the brake from the pallet∆ Unusual changesIn the event of unusual changes to the brake, the brake power supply must immediately be disconnected.Any unusual changes, e.g. development of smell at the brake, must immediately be reported to the person concerned or the customer service department notified in order to prevent the brake suffering further damage.∆ Overvoltage protectionFor brakes with coil outputs from 100 W and higher, overvoltage protection must be provided to preventdamage to the coil on disconnection of the brake power supply.Technical dataBrake connection dimensionsHub Bore H7Keyway Keyway width DIN 6885 page 1; P9Brake adapter flange Centring seatInner centringOuter centringH7f8Tightening torques for various bolt sizesThe following tightening torques apply to nuts and bolts:Bolt size Tightening torque MA (Nm)8.810.9M82536M104972M1285125M14135200M16210310M18300430M20425610M22580830M247301050Bolt and hexagon socket screw key sizes for manual release bolts of various brake sizesBrake size SFB, SFB-H brake Manual release boltsDIN 912 self-lockingHexagon socket screwkey DIN 911, key size:from 6.3 to 63M86 100M108 from 160 to 400M1210 from 630 to 1000M1614 Component DescriptionDrive technology6Drive technology 7OverviewBrake (outer)Manual release bolts under lock boltsAirgap measuring bolt HousingBrake adapter flange Rating plateCondensation water drain bolt for vertical installationBrake rating plateBrake designation Braking torque Factory set airgap Maximum airgapBrake serial numberOverview Drive technology8Brake (inner)Cap nut Sealing ring HousingO-ringLock nutsBrake flangeFriction lining groupManual release boltsArmature plateBoltSpringCoil body group with brake adapter flangeStud boltsConnecting cableInstallationThe brake can be fitted horizontally or vertically.Prior to fitting the brake, the following safety information must be observed:∆Shutdown equipment prior to fitting brakeBefore fitting the brake, it must be ensured that the equipment to which the brake is to be fitted •is shutdown and•secured to prevent accidental activation.∆Do not use any greaseThe brake is designed for dry-running operation. For this reason, no greases or oils must be used during installation of the brake. Greases and oils reduce the braking action. The hub in particular must not be oiled or greased.∆Danger of crushingWhen carrying out work on the brake, heavy tools are used. Particular attention should therefore be paid to possible crushing points when:•Using tools•Unbolting the brake from the pallet∆Use lifting equipmentThe brake can weigh between 19 and 750 kg depending on type. For brake installation purposes, lifting gear or another crane can be used.∆Do not use a crane that is being fitted with brakesUnder no circumstances should the crane to which brakes are being fitted be used for lifting purposes.∆Protection of inner brakeDirt, oil and spray water reduce the braking capacity. Friction linings, brake flange and armature platemust be protected when the brake is open.Drive technology9Installation Drive technology10FittingAlignment during fitting depends on the position of the motor or gear shaft.The brake must be prepared for fitting according to the following procedure:-Remove cap nuts and sealing rings - Remove housing-Simultaneously tighten manual release bolts evenly clockwise, so that the friction lining group moves freelyManual release boltsArmature plate Airgap Coil body group Friction lining group-Check that the lining group moves freelyIf the friction lining group does not move freely:-Simultaneously further tighten manual release bolts carefully and evenly clockwisePrior to fitting the brake:-KeyMotor shaftHub-Secure the hub axially with the shaft and washer or circlip.Installation With suitable lifting gear, lift the brake so that the adapter flange and brake can be cleaned and sealing compound applied, e.g. Curil K2.-Subsequently clean the motor flange and apply sealing compound.-Lift the brake with suitable lifting gear and carefully position the teeth of the friction lining group over the teeth of the driving hub.-Feed the connecting cable through the opening in the adapter flange as shown as illustrated.-Have electrical connections made by a qualified electrician.Also observe the safety information in the chapter “Electrical connection”. Array-After electrical connection, bolt the brake adapter flange to the motor flange.∆Observe bolt tightening torque.The prescribed tightening torque must be observed when tightening bolts (see “Technical Data)”.-Simultaneously unscrew both manual release bolts evenly counter-clockwise until the bolt heads just make contact with the brake flange.∆Do not unscrew manual release bolts with forceIf the manual release bolts are unscrewed with force over and beyond the resistance, the brake can be damaged.∆Ensuring correct braking actionA check should be made to ensure that the manual release bolts are unscrewed properly. If the manual release bolts are tightened, the brake will not operate or be restricted.∆Remove foreign bodies on O-ring and contact surfaces.When fitting the housing, the housing O-ring and contact surfaces must be from foreign bodies,otherwise the housing will not provide a proper seal.- Clean O-ring and contact surface.-Fit the housing noting the installation position, the mark on the housing must correspond with the mark on the adapter flange.Electrical connectionDuring installation, electrical connection of the brake must be established.∆ Only qualified electricianOnly a qualified electrician may connect the brake to the DC supply and check the current flow, taking into all safety measures. Incorrect connection may have fatal consequences!∆ EarthingThe brake must be earthed in compliance with the applicable regulations.∆ Disconnect system from the supplyThe supply must be disconnected before carrying out any work on the electrical system.∆ Provide overvoltage protectionBrakes with a coil output of 100 W and higher must be provided with overvoltage protection to prevent damage to the coil on disconnection of the brake power supply.∆ Prevent brake overheatingTo prevent the brake overheating, it must be ensured that the motor to be braked does not continue to run in the event of an undesired power failure.∆ Do not switch onDisconnect the power supply to the motor before connecting the brake.- Provide a “Do not switch on” sign at the switching point.- Establish electrical connection.-Remove the sign.Marks (notches)Brake adapter flangeHousingCommissioningPrior to commissioning the brake, the following safety information must be observed:∆Overloading the brakeThe operator is obliged to adjust the motor for the brake in such a way that the brake cannot be overloaded. Overloading the brake would cause heavy brake lining wear.Note: As a result of chemical degreasing at the factory, the armature plate and brake flange may have a bluish discoloration; this is not an indication of thermal overload.∆Risk of burns!During operation, the brake can reach temperatures up to 80°C. Any contact with the hotbrake housing must therefore be avoided.∆Maintain maximum speed rangeIn order to prevent damage to the brake, the brake must be operated also during commissioning only within the permissible speed range.Note: Loading case and technical data sheets must be observed.Function checkA function check must be carried out prior to each initial use. Observe the safety information beforecarrying out the function check:∆Do not place or leaving anything lying around in this areaRemove all metal or flammable objects from the working area of the brake.∆Do not reach into rotating brakeIf the function check is carried out with the housing removed, reaching into rotating brake must be avoided in any event.∆Seal replacementAll seals removed for the function check must be replaced with new seals.Commissioning Function check-With the housing removed, connect and disconnect the brake power supply several timesThe armature plate moves during switching between the coil body group and friction lining group.After completing function check:-The procedure for cleaning and fitting the housing is as described in the chapter “Installation” under the section “Fitting the brake”.Checking the airgapTo ensure correct operation of the brake, the airgap between the coil body group and armature plate must have the prescribed size. The minimum or maximum airgap is shown on the brake rating plate. The brake is set with the minimum airgap at the factory.Check the airgap through the open tapped holes at three points:Bolt with sealing ring- Unscrew bolts with sealing rings from the housing- Insert feeler gauge through the open tapped holes at all three points - Measure the airgap between the armature plate and coil body group.-Re-insert bolts with sealing rings and tighten. Old sealing rings cannot prevent the ingress of water.Mode of operation of the brakeConnection of the brake power supplyOn connection of the brake power supply, an electromagnetic field builds up. This causes the armature plate to be drawn towards the coil body group and the brake is released. The friction lining group of the brake can now rotate freely between the armature plate and brake flange.Disconnection of the brake power supplyOn disconnection of the brake power supply, the electromagnetic field collapses and the brake is applied.The pressure of the springs forces the armature plate against the friction lining group. The friction lining group simultaneously presses against the brake flange.The mechanical friction is transferred to the motor shaft via the friction lining plate and driving hub. The motor is braked.Running-in friction liningsWith the commissioning of the brake or after renewal of the friction lining group, the friction linings must be run-in. Only when this has been done is the specified braking torque fully transmitted.Several controlled braking operations should be carried out, bearing in mind that the full braking power is not initially available. Braking under full load must be avoided.OperationThe following safety information must be observed for operation of the brake:∆ Usual changesIn the event of any unusual changes to the brake, the brake power supply must immediately bedisconnected. Any unusual changes , e.g. the development of smell at the brake, should immediately be reported to the person concerned or the customer service department notified in order to prevent the brake suffering further damage.∆ Permissible braking energyThe permissible braking energy can be determined from the thermal load diagram.With a known switching energy per braking operation and number of braking operations per hour, the brake size can be determined. Example: Q = 100 kJ/switching energy and z = 35 braking operations/hour = brake SFB 100.Braking speed n = 1500 rpmBraking operation per hour z [1/h]Manual releaseReleasing the brake manually means briefly releasing the brake by manual actions and only in an emergency, e.g. in order to lower suspended loads carefully.The following safety information must be observed before releasing the brake manually:∆ Manual release only for emergenciesUnder no circumstances must the manual release be used for the purpose of maintaining temporary operation. It is intended for emergency use only.It must be ensured when releasing the brake manually that the power supply to the brake remains disconnected and cannot be accidentally reconnected.∆ Note position of loadIt is important to note the position of the load when releasing the brake manually and that the surrounding area is cleared before the load is lowered.∆ High brake temperatureDepending on the operating mode, the brake can reach high temperatures. It may therefore be necessary to wear protective gloves when releasing the brake manually. Contact with a hot brake when releasing the brake manually must be avoided as burns can result.The housing can remain fitted when releasing the brake manually.-Unscrew lock bolts with seals on the front of the housing. Figure 1Figure 1Figure 2Manual releaseManual release boltHexagon socket screw key DIN 911A i r g a p a c c o r d i n g t o r a t i n g p l a t eManual release-Simultaneously turn both manual release bolts evenly clockwise. Figures 2 and 3The armature plate is now drawn slowly towards the coil body group against spring pressure and the brake is released. Any suspended load should be observed when releasing the brake.-Carefully lower the load with the aid of the manual release bolts. The speed at which the load is lowered can be accelerated by turning the bolts clockwise and decelerated by turning counter-clockwise.-Set down the load.Cancelling manual release-Simultaneously loosen the manual release bolts evenly counter-clockwise and unscrew until the bolt heads just make contact with the brake flange. Figure 4-Refit the lock bolts with new seals.∆ Ready to operate conditionBrake releasedFigure 3Brake appliedFigure 4A i r g a p 0 m mturn clockwiseA i r g a p a c c o r d i n g t o r a t i n g p l a t eturn counter-clockwiseAfter setting down the load, the brake must immediately be restored to a ready to operate condition. Note: The brake is only ready to operate when the manual release bolts have been turned back to their original position. Figure 4Manual releaseMaintenanceBrake maintenance must be carried out in strict observance of the safety information provided here.∆Danger to life through incorrect maintenanceIncorrectly maintained brakes can be dangerous. For this reason, only trainedpersonnel may open and maintain the brake.∆Disconnect power supplyBefore carrying out any maintenance work on the brake, the power supply must bedisconnected and the appropriate sign provided at the switching point.∆Danger of crushingWhen working on the brake, heavy tools are used. Particular attention should therefore be paid to possible crushing points:•Using tools•Fitting and removing the brake, accessories or spare parts•Unbolting the brake from the pallet∆Only qualified electricianOnly a qualified electrician may replace electrical components such as coil bodies, contactors. For safety reasons, no description for the replacement of these parts is provided in these operating instructions.∆Use lifting equipmentThe brake can weigh between 19 and 750 kg depending on type. For maintenance purposes, lifting gear or another crane can be used.∆Do not use a crane being maintainedUnder no circumstances should the crane whose brakes are being maintained be used for lifting purposes.∆Active electromagnetic fieldsOn completion of maintenance work, all tools must initially be removed from theworking area of the brake.On connection of the brake power supply, the electromagnetic fields of the brake become active.Maintenance for the SFB and SFB-H is limited to:•Airgap check•Brake flange reversal•Friction lining group replacement•Brake flange and armature plate replacement•Condensation water drainageChecking the airgapRegular airgap checks are an integral part of maintenance routines. The inspection intervals vary depending on the use of the brake. Weekly inspection will ensure perfection functioning of the brake with average use.See Commissioning, page 16.If the airgap should exceed the specified maximum airgap, the brake flange must be reversed or the friction lining group replaced.MaintenanceBrake flange reversal∆Observe maximum airgapUnder no circumstances must brake flange reversal take place before the maximumairgap is reached.∆Observe safety informationThe safety information at the beginning of the maintenance chapter must be observed.Note: The brake flange can only be reversed once! The friction lining group must subsequently be replaced and refitted.When the maximum airgap is reached, the brake flange can be reversed:-Disconnect the power supply.-Remove cap nuts and sealing rings on housing and remove the housing.-Simultaneously tighten manual release bolts evenly clockwise with two hexagon socket screw keys (DIN 911).The friction lining group can now move freely.-Unscrew hexagon nuts.-Remove brake flange and clean as described in the chapter “Cleaning”.-Reverse brake flange and fit with the “new” side facing the armature plate.Maintenance∆ AttentionThe brake components are provided with small notches for marking purposes. The notches must be located one on top of the other in a line. Failure to observe this will result in brake malfunction or failure.-Tighten hexagon nut.When tightening the hexagon nuts, the tightening torque must be observed.-Simultaneously loosen manual release bolts evenly counter-clockwise until the bolt heads just make contact with the brake flange.∆ Remove foreign bodies on O-ring and contact surfacesWhen fitting the housing, the O-ring of the housing or the contact surface must be free from foreign bodies.- For cleaning and fitting the housing, proceed as described in the chapter “Installation”.-Subsequently check the airgap as described at the beginning of the chapter.Brake flangeFriction lining groupArmature plateCoil body groupMaintenanceBrake flange, friction lining group and armature plate replacement∆Observe safety informationPrior to replacement, the safety information at the beginning of the maintenance chapter must be observed.Friction lining group consists of:•Friction lining plate and•Friction liningThis group is subject to wear due to braking operations and must be replaced when worn. The replacement time depends on the braking frequency. Replacement is also necessary if the friction lining group has come into contact with•Oil•Grease•or similarBrake flange and armature plateLike the friction lining group, both these components are subject to wear. It is recommended to also replace the brake flange and armature plate with each second replacement of the friction lining group.Further use will reduce the life of the new friction linings.Procedure for the replacement of all three groups.-Disconnect power supply.-Remove housing.-Simultaneously tighten manual release bolts evenly clockwise.The friction lining group now moves freely.-Unscrew hexagon nuts on brake flangeOnly for brake flange replacement:-Remove brake flange and replace. Dispose of old brake flange.Only for friction lining group replacement:-Remove brake flange and clean as described in the chapter “Cleaning”.-Remove friction lining group and replace.∆Following replacement, the cooling ribs of the friction lining group must point towards the brake flange.Cooling ribsMaintenanceOnly for friction lining group replacement:-After fitting the friction lining group, the brake flange with the initial side can be fitted as described in the section “Brake flange reversal”. The marks on the brake flange must correspond with those of the other brake components.Only for replacement of all three components:∆Stand at the side of the brakeWhen replacing the armature plate, the full spring pressure of the brake is exerted. If the work is not carried out correctly, parts of the brake can loosen through the spring pressure and cause injury. It is therefore important to stand at the stand of the brake when the following work is carried out:-Loosen manual release bolts evenly and remove.-Remove armature plate and replace. When changing the armature plate, it must be ensured that the pressure springs do not fall out of the coil body group.-Fit new armature plate with the recess facing the coilbody group.Provided on one side of the armature plate is a recess. Theside with the recess must face the coil body group (seeillustration).Recess.This side must face the coil body group.To be noted for installation:The marks on the components must be in one line, as described in the chapter “Maintenance”.-Fit new brake flange and tighten with hexagon nuts.The mark on the brake flange must correspond with those on the other brake components.-Simultaneously unscrew manual release bolts evenly counter-clockwise until the bolt heads just make contact with the brake flange.∆Remove foreign bodies on O-ring and contact surfacesWhen fitting the housing, the O-ring of the housing or contact surface must be free from foreign bodies. -For cleaning and fitting the housing, proceed as described in the chapter “Installation” under the section “Fitting the brake”.-Subsequently check the airgap as described at the beginning of the chapter.Following replacement of the friction lining group, the brake must be prepared for normal operation as described in the chapter “Commissioning”.。

电磁刹车DWS40使用说明书

电磁刹车DWS40使用说明书

DWS40电磁涡流刹车使用说明书上海申通石油机械厂有限公司一、性能及说明DWS40型涡流刹车用作钻深为4000米的海洋或陆地钻机的辅助刹车,既可绞车成套供应,也可为矿场已经使用的钻机配套作为单独部件供应。

1、技术规范最大扭矩 60000N.m钻井深度 4000m作用原理感应涡流制动线圈个数 4每个线圈额定电阻(20°C时) 5.39Ω线圈绝缘等级H级励磁功率 12KW励磁电流(两串两并时)40A需用冷却水量285L/min最大出水温度(当进水温度42°C时) 72°C重量 6500kg二、结构电磁涡流刹车由刹车主体、可控硅整流装置及司钻开关等三部分组成。

1、刹车主体它由两个基本部分组成,如图一所示。

其一为静止部分,称为定子;其二为转动部分,称为转子。

在定子与转子之间有一定的气隙,称为工作气隙,电磁涡流刹车的刹车主体采用外电枢结构的型式,也就是说,其转子在定子外面旋转。

刹车的定子由磁极和激磁线圈构成。

磁极是磁路的一部分,采用电工钢制成,这种材料的导磁系数高,矫顽力小,以满足下钻时有用制动扭矩大,而起空吊卡时无用制动扭矩小的要求。

激磁线圈是刹车的电路部分,工作时通以直流电流,它固定于磁极上,与磁极组成一个整体成为定子。

刹车在运行时要产生大量的热量,因此激磁线圈采用了耐高温的电磁线与相应的绝缘材料,以保证线圈在高温下仍具有良好的绝缘性能。

图一电磁涡流刹车结构示意图1. 端盖2. 转子3. 机座4. 定子5. 激磁线圈6.上呼吸器7.下呼吸器刹车的转子通过齿式离合器与绞车滚筒轴相联,由绞车滚筒驱动,与滚筒同速旋转。

转子既是磁路的一部分,又是电路的一部分,采用电工钢制成。

它和定子磁极、工作气隙构成刹车的完整磁路。

2.可控硅整流装置:它由整流变压器和可控硅半控桥式整流电路组成。

用以将钻机交流发电机或交流电网供给的交流电压变成可调直流电压,给激磁线圈通以可调直流电流。

考虑到使用电磁涡流刹车进行下钻作业时,其下钻速度的调整精度、调节系统的稳定性以及过渡过程动态品质方面的指标都要求不高,因此采用比较简单的闭环调节系统即可满足钻井工艺的要求。

首先,电磁线圈通电后,引铁就会克服弹簧压力而被磁场面吸引,内盘和外盘之间形成间隙,内盘得到释放,制动器就松开了。

切断电源后,引铁被释放,通过弹力压回原位,引铁把内盘和外盘压向定位法兰面,通过摩擦力矩,制动器就会动作。

这样,磁场在无励磁的状态下,制动器正常工作。

电磁制动器的原理与设计说明书

电磁制动器的原理与设计说明书

1 引言1.1 课题研究的背景及意义制动器是保障汽车安全运行、取得预期运行效益的最基本的使用性能,因此汽车制造厂、使用者、汽车维修和管理人员都很重视车辆的制动性。

随着车辆技术的进步和汽车行驶速度的提高,这种重要性日渐突出,众多的汽车工程师在改进汽车制动性能的研究中倾注了大量的心血。

目前关于汽车制动的研究主要集中在制动控制方面,包括制动控制的理论和方法以及采用新的技术。

最原始的制动控制只是驾驶员操纵一组简单的机械装置向制动器施加作用力,那时的车辆质量比较小,速度比较低,机械制动虽已满足车辆制动的需要,但随着汽车自身质量的增加,助力装置对机械制动器来说已显得十分必要。

这时,开始出现真空助力装置。

1932年生产的质量生产的质量为2860kg的凯迪拉克V16车四轮采用直径419.1mm的鼓式制动器,并有制动踏板控制的真空助力装置。

林肯公司也于1932年推出V12轿车,该车采用通过四根软索控制真空加力器的鼓式制动器。

随着科学技术的发展及汽车工业的发展,尤其是军用车辆及军用技术的发展,车辆制动有了新的突破,液压制动(图1.1)是继机械制动后的又一重大革新。

Duesenberg Eight车率先使用了轿车液压制动器,克莱斯勒的四轮液压制动器于1924年问世,通用和福特分别于1934年和1939年采用了液压制动技术。

到20世纪50年代,液压助力制动器才成为现实。

1.前轮制动器2.制动轮缸3、6、8.油管 4.制动踏板机构5.制动主缸7.后轮制动器图1.1在液压鼓式制动器出现的若干年后,人们又发明了液压钳盘式制动器,盘式制动器又称为碟式制动器,顾名思义,是取其形状而得名。

由液压控制,主要零部件有制动盘、分泵、制动钳、油管等。

制动盘用合金钢制造并固定在车轮上,随车轮转动。

分泵固定在制动器的底板上固定不动。

制动卡钳上的两个摩擦片分别装在制动盘的两侧。

20世纪80年代后期,随着电子技术的发展,世界汽车技术领域最显著的成就就是防抱制动系统(ABS)的实用和推广。

广泛应用于塔式起重机回转机构电机的制动装置。

电风标的电动释放和手动释放的功能系用于塔机长期不工作时,使电机处于释放状态,从而使塔臂能随风自由转动调节至顺风方向,使塔臂迎风面积最小,使塔臂的迎风阻力最小。

注意:在电机正常工作时风标的电动释放动作不能使用,否则会造成电机制动器工作不正常,严重时会影响塔机的安全性。

2. 使用条件:2.1 海拔高度:≤1000m;2.2 环境温度:-35℃-40℃;2.3 相对湿度:≤90%;2.4 额定电源:DC24V(电压波动应不超过额定值的±10%)2.5 主要技术参数:2.6 工作制: S3-60%2.7 动作频率: 720次/小时2.8 制动盘额定退距(制动器出厂调整气隙): 0.8mm2.9 制动器允许最大气隙:1.5mm(达到该气隙需要立即调整)3.工作原理:电磁制动器为断电制动器(电磁制动器的结构请参见图1)。

当电磁制动器励磁线圈通入规定的直流电时,产生电磁吸力,吸合衔铁,带动摩擦盘、压缩制动弹簧,使制动盘处于释放状态,转轴可自由转动。

断电时,电磁吸力消失,制动弹簧推动摩擦盘,使制动盘处于制动状态,转轴不能自由转动。

Spring-set, Armature actuated direct-acting brake (AAB), DC voltage coilCarrier ring friction disc is standard with the 350 & 360 series and is an option in the SAB brakes F. MDescriptionSuitable f and severBrake OperationSolenoid Actuated Brakes (SAB) are spring set power released brakes, acting through a solenoid and lever mechanism.The 1-087-x00, 1-082-x00 and 1-086-x00 series brakes are self-adjusting for friction disc wear.The endplate mounts to a C-face register & bolt circle, usually on the non-drive end of a motor. The brake hub is attached to the keyed shaft. The friction discs fi t closely onto the splined outside diameter of the hub. When the coil is de-energized, the spring pulls the lever arm about a pivot point. This action applies spring force against the pressure plate compressing the pressure plate and friction discs within the brake endplate. The disc pack, hub and shaft are unable to rotate. A small single-phase AC, or DC, solenoid coil is used with the design’s mechanical advantage to remove the spring force and allow shaft rotation. Coil pull in and holding amper-age requirements are listed in Stearns Catalog #200.Armature Actuated Brakes (AABs) are spring set power released direct acting brakes.The brake hub is attached to a shaft. A carrier ring style fric-tion disc fi ts closely to the outside diameter of the splined hub. The magnet body contains compression springs and an electrical coil. When electrical power is applied to the coil, the armature is drawn to the magnet body, the springs are compressed and the hub and friction disc are able to rotate. When electrical power is removed, the brake is spring set. The spring force moves the armature across a small preci-sion air gap to clamp the carrier style friction ring between the armature and the mount surface which prevents hub and shaft rotation. The AAB coil requires DC voltage which can be supplied by a DC power source or an AC recti fi er.Stearns brakes operate at the selected voltage and frequency. Wire separately for use with a variable frequency motor drive (VFD).Catalog brakes can be modi fi ed with additional modi fi cations for use in severe duty or industry speci fi c applications.The full product catalog #200, sizing and selection charts, installation and part information is available at .HubFriction & Stationary DiscsTorque SpringEndplateMagnetCoilAir Gap Hub StoppedNavy Brakes - built to the former MIL-B-16392CDuctile Iron Enclosure, brass stationary and pressure plates in the disc pack.SAB Style: Power released spring set brakeAdditional modi fi cations will change the eighth through twelfth character of the part number.Modi fi cation necessary for vertical above or below mount.Adapters available for other C-face mount requirements.The Master Plan details materials, construction and dimensional informationSeries Plan R633 Carrier Plan 1-087-600N1-1087-602-A N1-087-602-D 1-082-600N1-1082-602-A N1-082-602-C 1-086-600N1-1086-602-AN1-086-602-CWeapon and cargo elevators specifying MIL-E-17807B are constructed with bronze carrier ring style friction discs, ductile iron stationaryand pressure plates.

DSZ1-MT电磁制动器 (DC110V)

DSZ1-MT电磁制动器 (DC110V)

一、结构原理:
制动器主要由磁轭、衔铁、摩擦盘、手动释放机构等零部件组成。

当磁轭中电磁线圈通电,由于电磁吸力作用,磁轭吸引衔铁并压缩弹簧,摩擦盘与衔铁、电机端盖脱开制动扭矩消失;当电磁线圈断电,制动器失去磁吸力,弹簧推动衔铁压紧摩擦盘,产生摩擦力矩。

制动器衔铁分成左右两块,由两组弹簧分别作用于衔铁和摩擦盘,符合电梯制动器的双制动要求。

二、主要技术参数
三、安装及使用:
1. 将连接键套固定在轴上,并装好轴挡圈;
将电机端面摩擦面上以及摩擦盘平面和衔铁
平面上的油污清除干净,将摩擦盘装在键套
上并靠紧电机端盖,并注意不要在摩擦面上
粘上油污;
2.用安装螺钉将制动器装上电机端盖,并通过塞尺仔细调节各个安装螺钉使间隙δ达到规定值0.25~0.3mm,并且四周间隙均匀。

调节好每个安装螺钉后,顺时针方向拧紧空心螺栓使其与电机端盖顶紧。

C B
A
3. 如果停车抱闸有溜车现象,把中间的两个螺栓(A)逆时针松动90°;如果还有溜车,先逆时针稍微松掉六个安装螺钉(C),再逆时针松掉六个空心螺栓(B),顺时针均匀调节六个安装螺钉(C),以曳引轮转动时没有摩擦声为好,气隙尽量小(这样抱闸声音较小),最后顺时针把空心螺栓拧紧。

(螺栓对角紧固)
注:可参照步骤2安装
四、维护保养
制动器应定期进行维护保养:
2.检查摩擦盘磨损情况,若发现裂缝或脱落,必须进行更换。

3.检查各螺栓是否有松动并拧紧。
