回转驱动产品技术详解
回转驱动产品技术概要一、基础技术简介：回转驱动是在回转支承产品上衍生出来的具有高集成度和大减速比，且结构简单、使用与维护方便的特殊回转减速产品，由于采用回转支承作为从动件和框架基础，利用回转支承的内外圈分别实现驱动动力的输入和输出，使得回转驱动不但可实现360度全周无止点的回转，而且可同时在回转支承框架基础上安装驱动动力源，因此其传动效率高，是机械传动装置家族中的新成员。
又因其实质是一种减速装置，所以也可称为回转减速器、转盘减速器或驱动转盘。
回转驱动按照传动形式不同可分为齿轮传动和蜗轮蜗杆传动两类，根据传动副封闭形式不同又可分为开式和闭式两类，形式最简单的回转驱动就是应用在挖掘机、塔吊等工程机械产品上的驱动转盘，作为减速传动链的最后一环，这种回转驱动为开式齿轮传动，其前端还需配置一个大减速比的行星减速器作为其动力输入，所以只能称之为回转驱动的雏形，为扩大此类产品的应用范围，进一步提高产品使用和维护的便捷性，开发出了集成式蜗轮蜗杆传动的回转驱动，为了更进一步提高产品的驱动能力，包络蜗杆传动也被应用在此类产品上，配置有包络蜗杆的回转驱动不但驱动扭矩增大，驱动精度也进一步提高，更可进行数字化控制，故广泛应用于太阳能和风能发电设备上的跟踪和微调装置，另外在机器人、雷达、低速重载起重、举升设备、精密数控转盘等产品领域均有良好的应用效果。
汗王品牌回转驱动产品系采用自主技术和工艺开发的适应市场需求的高质量回转驱动产品，汗王品牌拥有全品系多规格的成熟回转驱动产品以及为客户需要定制设计和制造此类产品的能力，对于需要低速重载荷、高速中载荷和高速轻载荷的不同应用，汗王均可提供对应的产品或解决方案。

滚珠丝杠选型
滚珠丝杠副特性滚珠丝杠传动系统是一个以滚珠作为滚动媒介的滚动螺旋传动的体系。
以传动形式分为两种：（1）将回转运动转化成直线运动。
（2）将直线运动转化成回转运动。
•传动效率高滚珠丝杠传动系统的传动效率高达90%～98%，为传统的滑动丝杠系统的2～4倍，如图1.1.1所示，所以能以较小的扭矩得到较大的推力，亦可由直线运动转为旋转运动（运动可逆）。
•运动平稳滚珠丝杠传动系统为点接触滚动运动，工作中摩擦阻力小、灵敏度高、启动时无颤动、低速时无爬行现象，因此可精密地控制微量进给。
•高精度滚珠丝杠传动系统运动中温升较小，并可预紧消除轴向间隙和对丝杠进行预拉伸以补偿热伸长，因此可以获得较高的定位精度和重复定位精度。
•高耐用性钢球滚动接触处均经硬化（HRC58～63）处理，并经精密磨削，循环体系过程纯属滚动，相对对磨损甚微，故具有较高的使用寿命和精度保持性。
•同步性好由于运动平稳、反应灵敏、无阻滞、无滑移，用几套相同的滚珠丝杠传动系统同时传动几个相同的部件或装置，可以获得很好的同步效果。
•高可靠性与其它传动机械，液压传动相比，滚珠丝杠传动系统故障率很低，维修保养也较简单，只需进行一般的润滑和防尘。
在特殊场合可在无润滑状态下工作。
•无背隙与高刚性滚珠丝杠传动系统采用歌德式（Gothic arch）沟槽形状（见图2.1.2—2.1.3）、使钢珠与沟槽达到最佳接触以便轻易运转。
若加入适当的预紧力，消除轴向间隙，可使滚珠有更佳的刚性，减少滚珠和螺母、丝杠间的弹性变形，达到更高的精度。
现代制造技术的发展突飞猛进，一批又一批的高速数控机床应运而生。
它不仅要求有性能卓越的高速主轴，而且也对进给系统提出了很高的要求：(1)最大进给速度应达到40m/min或更高；(2)加速度要高，达到1g以上；(3)动态性能要好，达到较高的定位精度。
高速滚珠丝杠副是指能适应高速化要求(40 m／min以上)、满足承载要求且能精密定位的滚珠丝杠副，是实现数控机床高速化首选的传动与定位部件。

Slew Drives are designed for grease lubrication.In a Slew Drive the rolling elements (6) carry the load between theinner ring (7) and outer ring (8). The raceway system’s capacity isdetermined predominantly by Slewing Ring design, the depth ofhardening and the number and size of the rolling elements. Spacers(9) separate the rolling elements and minimise friction and wear.F axF radM KLoad distributionDepending on external load, the load distribution contact and theangle around the rolling elements will vary.In the case of axial load, all rolling elements are loaded in the samedirection.In the case of radial load, a segment of the rolling elementscarries the load.In the case of tilting moment load, a segment on one side and asegment on the opposite side carry the load.Mostly, a combination of axial, radial and tilting moment loadsoccur.••••19624357832TorqueThe operating torque may not exceed the maximum torque specified in the Technical Data section, calculated with application service factor 1. Explanations of different torque specifications are as follows:Series SP:Maximum torque M d max :Slew Drive series SP-H, SP-M:Maximum torque is limited by maximum radial load of the planetary gear-set used.Slew Drive series SP-L, SP-I:The maximum torque is calculated with a safety factor against static tooth base fracture SFS 1.75.Nominal torque M d nom :The nominal torque is calculated with a safety factor against tooth base fatigue SF1, at the rotational output speed specified in the Technical Data section, under one-way varying load.DutySlew Drive series WDs are designed for intermittent duty. Application with continuous running or with higher rate of duty and simultaneously high output torque are not permissible.This would lead to unacceptable temperature increase in the gearing and thus to premature failure of the Slew Drive.Transmission of the maximum torque is to be limited to 10% of each minute. Please check the diagram for the maximum permissible duty per minute of the respective series on P . 53 and P . 63.Static capacity of racewayStatic capacity of the Slew Drive is determined by:• Hardening depth of the raceway• Number and size of the rolling elements • Slewing Ring design • Raceway geometryThe limiting load diagram shows permissible axial and tilting moment loads for a respective size unit.Every loading case including the required or recommended safety must lie below the limiting load line.Series WD:Maximum torque M d max :The calculation of the maximum torque with a safety factor against tooth fracture SFS 1 is done according to G. Niemann / H. Winter, Machine Elements, Band III, 1986,for worm gears and is influenced by:• Limiting value of tooth base stress • Module• Gearing widthNominal torque M d nom :The nominal torque is calculated with a safety factor against tooth wear of SF1,• at the output speed specified in the table • for a calculated service life of 10,000 h • at a duty of 5%For Slew Drives with two motors, the specified values are valid for a slewing angle of ≤ 170°.Series SP and WD:Maximum holding torque M h :The maximum holding torque determines which retroactive torque can be transmitted or held without damage being caused to the gearing. In general, the value of the maximum torque is assumed.Rotational speed Slew Drive series SP:The maximum permissible speed isSlew Drive series WD:The maximum permissible speed is specified in the Technical Data section. For higher speeds, our Engineering Department should be consulted.Limiting load diagrams are valid under the following condition:Static loadingLimiting load line with safety 1Clamping length of bolts, minimum 5-times, maximum 10-times the bolt diameterContinuous threads up to the bolt head is not permissibleBolts of quality class SAE Grade 8 for series WD-LA and quality class 10.9 according to DIN EN ISO 898 for the other series All mounting holes used “Compressive” loadAdequately stiff and level mounting structure (see chapter “Installation and Maintenance Instructions” on P . 46 - 51)Minimum strength of the mounting structure 72,520 lbs/in 2Radial loading considered as specifiedCompliance with “Installation and Maintenance Instructions“•••••••••••1570D Ln perm =34Radial loads must be transmitted by means of frictional contact between Slew Drive and the attached structure.A good bolt connection is vital for satisfactory function of the Slew Drive. Bolt connection and tilting clearance of a Slew Drive must be checked regularly.••Axial loads can be “compressive“ or “suspended”.A “suspended” axial load and the load on a rising segment in tilting moments must be adequately resisted by mounting bolts.••GearSlew Drives of series WD are designed with worm gear.Slew Drives of series SP are designed with spur gear. Permissible torque is specified in the Technical Information section.DriveDrive is provided by either an attached hydraulic or electric motor.Both motor mountings as well as the shaft/hub connection conform to industrial standards, hence hydraulic motors available on the market can be mounted without difficulty.For electric motors, corresponding adapter pieces are necessary. The design specification for drive motors is undertaken by IMO, based upon rotational speed and torque information provided by the customer.HousingHousing is designed as a welded or cast component and adapted to the size of the Slew Drive. As a standard feature, housings are supplied with a priming paint.All catalog bolt data is valid only for “compressive” loads!SealingPolymer seals protect the Slew Drive from normal dirt penetration,dust and light sprayed water. For very dirty and wet environments,the seals shall be protected with pre-mounted labyrinth seals on the mounting structure.Performance and reliability of a Slew Drive depend strongly on avoiding ingress of contaminents to the interior of the unit.Pressure washing must not be used to clean Slew Drives.Operating temperatureStandard version IMO Slew Drives can be used in ambient temperatures from –4°F up to +158°F .Selection criteriaThe following criteria must be considered for the correct selection of a Slew Drive.Position of the output shaft Vertical:Slew Drives of all series can be used(even with a self-locking gear).Horizontal:Alternating:Slew Drives of all series can be used with exception ofseries WD-H. Here, it is necessary to use a Slew Drive with a 2-start gear, since using gear with self-locking and external driving force does not ensure smooth (jerk free) operation.Slew Drives provided with self-locking gear cannot beused. Using a Slew Drive of series WD-H with 1-start gear without self-locking is possible only up to 10°inclination angle to the vertical, otherwise smooth operation cannot be guaranteed.Slew Drives that are not self-locking can, as an option, be equipped with a locking brake, if required (see optional attachments for details).Caution: Catalog bolt data is not valid in this case!LoadsExternal forces such as axial load, radial load and tilting moment must lie below the static limiting load curve, as regards their operating load point. For this, please refer to the chapters “Static capacity of raceway“ and “Mounting bolts”.Shocks, vibrationsTo account for the peculiarities of different applications, the shock factors for gears should be considered. Slew Drives of the series WD are not suitable for applications under permanent vibration.Back loadKeep in mind that in the case of series WD Slew Drives, due to the high gear ratio, that in the case of back load (e.g. caused by boom impacting on obstacle), there is danger of irreparable damage to the worm gearbox, so long as the driving torque exceeds the maximum permissible table values Md max .36To address the peculiarities of different applications, the following application service factors are to be considered in the prevailing Application service factors are to be considered in the following equations for the prevailing loads:Slew Drive: pre-selected SP-M 0741/2-05894The following values are achieved with an application service factor of 1.25:F axD = F ax • f aTo account for the prevailing radial load, the tilting moment is increased accordingly.This equation applies only if:Should the value be exceeded, the limiting load diagram no longer applies.Please contact our Engineering Department.Calculation example:Application:Load:Slewing equipment for a construction machine under normal operation Axial loadRadial loadTilting moment load lbs lbs ft-lbsF axD = 12,400 • 1.25 = 15,500 lbsAt this point it can be verified in the limiting load diagram, whether or not the pre-selected Slew Drive is statically adequate.If the operating load point lies below the limiting load line then the Slew Drive is statically adequately dimensioned. If loads frequently occur during the slewing process, the selected type should be reevaluated dynamically for lifespan. For this, please contact our Engineering Department.Mounting boltsPrevailing loads must be safely transmitted. T o ensure this, mounting bolts should be sized to handle the raceway loading.The bolt curve is depicted in the static limiting load diagram, subject to the following conditions:Caution: In the case of “suspended” loads, the bolts are subject to additional tensional forces.Please contact our Engineering Department.Static load carrying capacity of mounting boltsDetermining the operation load level, both with and without radial load, occurs along with the verification of the static load carrying capacity of the raceway.If the prevailing load case lies below the limiting load line in the static limiting load diagram then the bolt connection is statically adequately dimensioned.•••Quote the fulfillment of the conditions in the case of considering the static load Slew Drive capacity of the raceway.Bolts are appropriately tightened with a torque wrench(bolt tightening factor αA = 1.6). For tightening torques, see table P . 48For Slew Drives with through holes, use the largest possible metric bolts with regular threads.M kD = (M k + 0.1442 • F rad • D L ) • f aF rad ≤ 0.0671 • M k + 0.5 • F ax12,4001,40064,000M kD = (64,000 + 0.1442 • 1,400 • 29.173) • 1.25= 87,362 ft-lbs37Friction torqueThe friction torque in Slew Drives depends upon many influence factors, e.g.:• Rigidity and flatness of the mounting structure • Load and loading combination• Rotational speed and operating temperature • Design of Slew Drive• Number and frictional torque of seals • Lubrication grease and level of filling • Manufacturing tolerances • Other factorsThe friction torque of an unloaded Slew Drive can be determined approximately with the following equations:Slew Drive series SP , with minimum Slew Drive clearance greater than zeroM wA = 0.0476 • D L 2Slew Drive series WD-L, with preloaded Slew DriveSlew Drive series WD-H, with preloaded Slew DriveDynamic load Slew Drive capacity of mounting bolts Mostly, static dimensioning of a mounting bolt is sufficient.In cases where very high numbers of stress reversals act on the Slew Drive, dynamic verification is necessary. For this, please contact our Engineering Department.Pressure lock of mounting boltsWhen radial loads act on the Slew Drive, it must be ensured that these loads can be transmitted without shearing forces occurring inside the bolts. Therefore, it must be determined whether the radial load can be transmitted via frictional contact between the mounting structure and the Slew Drive.n b = number of fixing holes per ringF sp = pre-stressing force on a mounting boltIf the prevailing radial load exceeds the limit value, we request that you contact our Engineering Department.F rad max =n b • F sp18.8For Slew Drives with a different number or size of bolts in the inner and outer ring, the permissible radial load is to be determined for both rings. The smaller value is the limiting value.Frictional contact prevails if F rad max is greater than the prevailing radial load.Slew Drives, series WD-H, are basically to be centralized.Securing the mounting boltsWhen a customer desires that the mounting bolts be secured, we recommend the following products (manufacturer specification is valid):Loctite ®Application of Loctite 270 is suitable for the highest level ofconnections. This prevents loosening and the threads are also sealed.Nord lock ®Nord lock, self-locking washers, are recommended for cases of vibration or dynamic loading cycles. Due to a pair of square tapered washers with tapered surface gradients between both Nord-lock securing washers greater than the gradient of the bolt threads, any loosening tendency of the bolt is immediately prevented.Other bolt securing systems are not recommended.The friction torque for a Slew Drive under load can be determined with the following equation, approximately:M w = 0.000417 • (52.8 • M k + 4 • D L • F rad + D L • F ax ) + M wAGearSlew Drive series SP Type of gearSlew Drives series SP are provided with spur gear according to DIN 3960, DIN 3962 and DIN 3967.If higher torque is necessary or longer operating lifespan is required,it is possible to manufacture the gear in tempered or hardened form.Permissible torqueCorresponding data is available in the Technical Information section.Drive pinionThe pinions used in different sizes are provided with hardened gear.In the Technical Data section you will find data about transmission ratios and numbers of teeth.For the direct drive (SP-L, SP-I), the drive pinion is equipped with a radial bearing that is integrated in the motor flange.In the case of Slew Drives equipped with planetary transmission, the drive pinion is mounted via the planetary transmission.M wA = 0.476 • D L 2M wA = 0.952 • D L 238LifespanThe expected lifespan of the gear depends on the operating conditions.The following factors are key:• Torque• Output speed • Duty factor• Ambient temperature, etc.LubricationTo ensure flawless operation and long usable life, adequate and regular lubrication is necessary. The grease fulfills the following functions:For the raceway:• Reduction of friction and wear in the rolling contacts • Corrosion protection • Lubrication of seals• Additional sealing effect of the grease “collar”For the gears:• Smooth running • Less wear• Reduced operation noise • Longer operating life • Less heat development Initial greasingIMO Slew Drives are supplied pre-lubricated. High-quality lithium-complex grease, based on mineral oil, with EP-additives according to DIN 51825, KP2P-20 is the standard lubrication.Regreasing intervalsRegreasing must be done at regular intervals, depending on frequency of use and ambient operating conditions. General attention must be paid to ensure that the grease used during the greasing is compatible with the sealing material. Special attention should be paid to ensure that lubricating grease types originally specified are used throughout the life of the unit.Should you wish to use other types of grease, it must be verified whether the grease is compatible with that used for initial greasing.Please contact your grease manufacturer.Please observe also the data in the “Installation and Maintenance Instructions” chapter.Beside regular regreasing during operation, it is also necessary to grease the Slew Drive after long standstill periods. Equally important is to grease the equipment in which the Slew Drive is integrated after cleaning.Tooth backlashTooth backlash is factory-set at the highest point of the gear. It depends on the module of the gear and is calculated according to the following formula:Tooth backlash to be set = 0.00118 to 0.00157 • module Slew Drive series WDDesign of the gearSlew Drive series WD is designed with a hardened worm gear according to DIN 3960, DIN 3962 and DIN 3967,Permissible torqueCorresponding data is provided in the published T echnical Information section.Worm shaftWorm shafts are made of hardened steel, with ground tooth flanks.Tooth backlashThe tooth backlash is set at approx. 0.0118 in for Slew Drive series WD.Self-lockingSeries SP Slew DrivesSeries SP Slew Drives are not self-locking.Series WD Slew DrivesSelf-locking only exists in the case of series WD Slew Drives if it cannot be driven from the output side. Self-locking is directly related to the efficiency of the Slew Drive, which depends on very many factors, e.g.• Lead angle• Angle of friction • Rotation speed • Lubrication• Material matching • Surface finish, etc.Theory indicates self-locking occurs if the gear efficiency is < 50%.Data in the Technical Data section conforms to this statement.However, it is vital to determine the actual existence of the self-locking characteristics in the supplied Slew Drive individually during actual usage.We take no responsibility for conformity of the theoretical data in the Technical Data section with the practically prevailing self-locking or non-self-locking characteristics.Shock coefficientAs for the applications in which impact is expected, the appropriate impact coefficients must be considered when determining the Slew Drives’ maximum torque rating.39ATTENTION:Slew Drives must not be cleaned with pressure washing equipment. During pressure washing, large amounts ofpressurized water can penetrate into the Slew Drive through the sealing gap and cannot be removed, even by massive re-greasing. This will strongly reduce the usable lifespan of a Slew Drive.Mixing greasesGrease with different thickener and base oil should generally not be mixed. The manufacturer should always confirm if different grease types can be mixed.Shelf life of lubricantsLubricants are subject to ageing even if unused. If after 3 years grease is not yet used, it should be replaced.Design of mounting structureSafe transmission of application loads and reliable operation of Slew Drives is achieved, along with other factors, through using adequately designed mounting structures.To ensure safe operation of Slew Drives, there are certain minimum requirements to the mounting structure.• Sufficient rigidity (see “Installation and Maintenance Instructions”)• Maintain flatness according to “Installation and Maintenance Instructions“• No hard points (e.g. through cross beams)• Surfaces for bolts must be machined plane • Hollow mounting structure is preferred • Use all mounting bolts• Bolts of recommended strength should be used• Minimum strength of attached structure 72,520 lbs/in 2Very different mounting structure solutions can be used, depending upon maximum load and application.If hollow mounting structure is designated for attached structure,flange thickness should be at least 50 % of Slew Drive’s overall height. The thickness of the hollow mounting structure should be about 30% of flange thickness. For weight-critical applications,flange thickness can only be reduced if appropriate stiffening ribs are provided and the specifications on permissible flatness and perpendicularity deviations and deformation under load are upheld.Values on this are specified in the“Installation and Maintenance Instructions“ P . 46 - 51.。

图1堆取料机回转驱动主要布置形式2以斗轮堆取料机回转驱动为例原始参数：回转机构支承132.50.3550，03，模数m=22，齿数Z1=176，变位系数X1=+0.5，驱动装置由卧式电动机+安全连轴器+制动器+行星减速器+小齿轮，6级电机。
回转部件总质量Gi=回转轴承承载轴向力Fa=2028400N，径向力Fr=50760N斗轮挖掘力F挖=14448N，滚道平均直径D=3550mm，重心相对回转中心最大偏移量（非工作）Li=1.5m。
2.1电机功率选择1）臂式斗轮堆取料机的回转阻力矩主要有摩擦阻力距T摩、坡道阻力矩T 坡、风阻力矩T风、启动惯性力矩T惯（带物料）或侧向切削力矩T切。
通常侧向切削力矩T切>启动惯性力矩T惯（带物料），所以计算电机功率时不考虑启动惯性力矩T惯。
