福伊特VOITH液力耦合器英文手册
Voith TurboCouplingswith constantfilling12As an expert in difficult applications in pow er transmission Voith continues to meet the increasing requirements through innovative product design and performance.Constant-fill Voith Turbo Couplings are used w ith electric motors in a wide range of applications, especially w hen highest pow ers, economy and reliability are required.The Voith Turbo Coupling with its in-herent hydrodynamic advantages has proven itself in millions of applications worldwide:I smooth acceleration of the largest massesI suitable for economically priced squirrel cage motorsI load free start-up and run-up of motorI no motor modification requiredI torque control during start-upI effective shock-absorptionI overload protection for motor and machineI load compensation for multi-motor drives.3cal contact between power-transmit-ting parts.The coupling contains a constant q uantity of operating fluid, usually mineral oil.The torq ue transmitted by the drive motor is converted into kinetic energy of the operating fluid in the pump wheel to which the motor is connect-ed. In the turbine wheel, this kinetic energy is converted back into me-chanical energy. When it comes to the function of the coupling, three modes are to be noted:Föttingers concept –Design and functionStartingThe pump-wheel acceler-ates the operating fluid as revolutions in the drive-motor increase, so that a circular flow of fluid is created in the working chamber. The entire blad-ed surface of the turbine wheel is impacted and thus set in motion through kinetic energy. The torque development during the starting procedure is indi-cated by the characteristic curve of the coupling.StationaryAll operating fluid in the coupling is staticOperation at Normal RatingOwing to the minimal dif-ference in speed between the pump and turbine wheel, a constant flow is achieved in the coupling.Only the demand torque from the machine is trans-mitted.Through skillful coordina-tion of compensating chambers, such as the delay chamber and the an-nular chamber shell, the starting performance of the Turbo Coupling can be reg-ulated (see characteristic curves on page 4).A suitable coupling for any drive Essential performance factors for a Arraycoupling are the power and speed ofthe drive motor.Having established the nominalpower and speed required, the dia-gram on the right enables determina-tion of the appropriate size of thecoupling.Different conditions require differentstarting procedures (characteristiccurve) for the coupling. Important cri-teria in this respect are the mass mo-ment of inertia, torque limitation andfrequency of start-ups.In the table below different types ofcouplings and their starting conditionscan be compared.Typ TTyp TVTyp TVVTyp TVVS45Turbo Coupling Type T is the basic version of c onstant-fill c ouplings,onsisting of pump wheel, turbine wheel and outer shell.A further range has been c reated by the addition of other parts to this basic type.The turbo c oupling is normallymounted on the mac hine shaft orgearbox shaft to be driven (outer wheel drive). In order to c ompensate for any slight installation inaccuracies,a flexible connecting coupling is usedto join c oupling and input shaft. Op-tional designs are available for mountarrangements whic h are radially re-moveable without disturbing motor and reducer alignment.Installation of this type of coupling is re ommended when vibration and overload protec tion are required for motor and machine; they may also be used for simpler transmission systems in the lower performanc e range.The basic type –Turbo Coupling ”Type T”Applications–Bucket-wheel equipment –Excavators–Mixing, kneading and stirring machines6This version features a ”delay-fill chamb er“ which is flange-connected to the outer wheel of the coupling (Type TV). At stand-still, a proportion of the working fluid lies in this cham-b er, thus reducing the volume in the working chamb er. Hence on motor start-up, a reduced coupling torque is transmitted, simultaneously providing an unloaded motor start. After the motor has run up, the working fluid flows from the delay-fill chamber into the working chamber which smoothly accelerates the driven machine up to its operating speed.Furthermore, if the application so demands, the delay-fill chamb er can b e further enlarged (Type TVV), thus enhancing its effects and further re-ducing the coupling torque on motor start, as well as resulting in even longer and smoother start up of the driven machine.In certain cases, the function of the delay chamb er can b e additionally improved through centrifugally con-trolled valves (Type TVF) or through hydrodynamic refill (Type TVY).Smoother start up –Turbo Coupling ”Type TV” and ”TVV”Applications:– Belt conveyors – Chain conveyors– Centrifuges, decanters – Tube Mills– High-inertia machinesA further Voith development is the an-nular-chamber shell additional to theenlarged delay chamber (Type TVVS).The additional chamber in thecoupling shell enables f urther reduc-tion of the starting torque. During theinitial rotations of the start-up proce-dure, centrifugalforces cause theouter chamber of the coupling to becompletely f illed with operating f luidfrom the bladed area.In comparison with couplings withoutannular chamber, filling of the bladedarea of a TVVS Coupling is consider-ably reduced, which, in turn, reducesthe torque transmitted during motorrun-up.The increase in torque then f ollowsthrough gradual emptying of the fluidfrom the delay chamber into the blad-ed area.The starting procedure can be adapt-ed to the requirements of the applica-tion by adjustable nozzle screws.This new concept f or couplings wasdesigned especially for conveyor beltdrives. Through the gradual build upof torque an automatic adaptation tobelt load conditions is achieved.The innovative one –Turbo Coupling ”Type TVVS”Application– Belt conveyors8The ”v“-be lt, timing be lt, or flat be lt pulley which is flanged to the bearing cover allows various transmission ra-tios to be accommodated. If required,the pulley may be easily exchanged.TRI and TVRI type Turbo Couplings are normally installe d on the motor shaft in an ove rhung position. The belt force is supported by a bearing in the be aring cove r on the coupling hub.TRI type Turbo Couplings can be in-stalled both as starting aid and over-load protection. Type TVRI with addi-tional de lay chambe r is re comme nd-ed if a particularly smooth start-up is required.For pulley drives –Turbo Coupling ”Type TRI/TVRI”Applications– Centrifuges and decanters – Fans – Mixers – Crushers9MTS mechanical thermal switches As protection against overheating, fu-sible plugs are standard.In order to avoid los s of operating fluid through thermal overload, a me-chanical thermal switch – MTS – can be added.On achieving the res pons e tempera-ture, the element activate a pin which then operates a switch.Depending on the type of circuit, the signal can be used either as an alarm or to switch off the motor.The circuit element has to be re-placed after activation.Monitoring devices and accessoriesBTS – Non-contact thermal switch Monitoring of coupling temperatures take splace without any contact.After activation of the s witch, no re-placement of the element is required.It is ready for us e as s oon as the coupling has cooled down.The s ignal can be us ed either as an alarm or to switch off the motor.In s ome cas es BTS can be us ed as speed monitor.Fitting and dismantling tool Required for profes s ional, s afe fitting and dismantling.As well as the mechanical fitting and dismantling tool, a hydraulic pressure device is available.Sight glassBy fitting a sight glass, the fluid level in the coupling can be easily checkedwithout opening the coupling.10In order to prov ide solutions for an ev er greater v ariety of applications,our engineers and technicians hav e dev eloped additional types of con-stant-fill couplings.Turbo Coupling with solid shaft and primary coupling flangeThe coupling is fitted rigid to the motor shaft ov er a primary coupling flange. The weight of the coupling is thus carried by the motor shaft and the load on the drive shaft is relieved.An elastic connecting coupling is re-quired between the solid shaft on the output side and the driven shaft.By using a specially designed flexible connecting coupling it is possible to fit or dismantle the coupling radially without moving motor or gears.For special applications –Additional typesTurbo Coupling with brake flange For use with a breaking system, the turbo coupling can be equipped with an additional brake flange to which a brake-drum or brake-disc is fitted.Turbo Coupling with twin circuit “Type DT”This coupling has two co-axial work circuits operating in parallel.By means of a double circuit the out-put of the same size coupling is effec-tively doubled.The properties, s uch as s tarting and overload protection are comparable with thos e of bas ic Type T without delay chamber.For available sizes of Turbo Coupling Type DT see performance characteri-stic diagram on page 4.Pulley-type couplingwithout bearing cover Type TRIThis type is ideally suited for particu-larly small belt discs.The pulley with integral bearing isflanged directly to the coupling shell.Subs equent replacement of the beltdisc would be costly.Turbo Coupling with overhungpulley installation – Type TRIn this simplified version of the pulleycoupling, the pulley is fitted to thecoupling shell in an overhung fashion.Turbo Coupling TR is an economicals olution for applications in the lowerpower range.11G R O U P O F C O M PA N I E SC r 128 eVoith Turbo GmbH & Co.

液力偶合器使用与维护手册
液力偶合器使用与维护手册一、液力偶合器的作用1、具有减缓冲击和隔离扭振的性能;可以使电机起动有一个延迟时间,缓慢加速,减少骤然起动而引起的零件间的相互冲击。
2、具有使电机轻载起动性能:由于偶合器的泵轮力矩与其转速的平方成正比,故当起动瞬间泵轮因转速低而力矩甚微,电机近似于带泵轮空载起动,所以起动时间短,起动电流小,起动平稳,尤其适合起动大惯量沉重负载。
3、具有过载保护性能:由于偶合器无机械直接连接,当外负荷超过一定限度后,泵轮力矩便不再上升,此时电机照常转动,输出减速直至停止,从电源吸取的功率转化为热能使偶合器升温,直至易熔塞喷液,从而输入与输出被切断,保护了电机,工作机不受损坏,从而降低了机器故障率,维护费用和停工时间,延长了电机荷工作机使用寿命。
4、具有节电的性能:由于偶合器有效地解决了电机起动和“大马拉小车”的现象,与刚性传动相比至少可降低一个电机机座号,加上可以降低起动电流和持续时间,降低对电网的冲击节能率达10—20%,尤其在起动大惯量沉重负载时更为显著。
限矩型液力偶合器的特点:除轴承和油封外,无任何机械磨檫,使用寿命长,故障率低,不需特殊维护保养。
二、调速型液力偶合器使用与维护1、启动前检查(1)检查油标确认油位是否合适;(2)检查偶合器、冷却器管路是否连接正确;(3)检查各仪表电气线路是否连接正确;(4)检查联轴节及防护罩是否安装正确;(5)检查偶合器油箱油量是否合适,当油温低于5℃时,应用电加热器将工作油加热;(6)检查偶合器导管是否调整至低转速装置。
2、运行(1)偶合器配有电动执行器,通过手动。
手操电动或自动控制电动执行器,来调节导管的位置,改变偶合器腔内的充液度,从而改变偶合器的输出转速与输出扭矩。
(2)偶合器的导管全插入(0%位)转速低,导管全拔出(100%位),转速高(可达额定转速与额定功率)。
导管开度从0%位向100%位置调整时,速度不宜过快,通常在25秒以内。
(3)偶合器调速范围,随工作机不同而不同。

电机产生的力矩加速了主动轮(泵轮)中的工作油,加速了的流体冲入从动轮(油涡轮),由于流体只能依靠压降在主从轮间的流通,这要求从动轮的转速低于主动轮的转速,这样在功率传输的过程中必须有一个转速的滑差。
选择合适的液力偶合器尺寸以满足满负荷功率传输时滑差较小。
输出的转速可以通过在主从动轮之间的油室油量来调节,这需要相应的改变勺管的位置,它决定了油室的充油量。
传动过程中滑差引起的功率损耗会使工作油温升高,通过冷油器使其温度降低。
2.油回路工作油和润滑油使用的是同一种油。
提供工作油循环和润滑油循环的齿轮泵由偶合器的输入轴驱动。
启停、故障的情况下由辅助油泵提供润滑。
2.1工作油回路工作油循环由一个闭式回路和一个叠加在它上面的开式回路构成,因此充油过程可以是变化的。
齿轮泵通过一个压力整定阀(24)进入工作油回路来对液力偶合器注油。
通过一个可调的节流口供给偶合器的工作油通过勺管调节油量。
在动态压力的作用下工作油通过分配室,工作油冷油器,可调节流口回到偶合器。
齿轮泵提供的多余油量通过另一个压力释放阀(31)回到油箱。
工作油和润滑油的压力通过两个压力释放阀设定。
当闭式油循环中断同时液力偶合器的油上升到180℃,易熔塞熔掉,被易熔塞堵住的孔开始放去偶合器的油。
如果易熔塞的熔掉是由于短暂的热力过载(例如冷油器故障或偶合器过负荷),偶合器控制方式只有轻微的改变。
但是,油箱油温上升、电机启动时间过长、接近最大输出功率对偶合器控制方式的改变是很明显的。
2.2润滑油回路齿轮泵将油箱中油加压后经过逆止阀、润滑油冷油器和可切换的双滤油器送到各个轴承、压力开关和传动齿轮。
