Fluid couplings

Fluid couplings

    Having a highly efficient and reliable drive system increases production and provides peace of mind. Whether you require fluid couplings or a customized drive package, Voith is your partner of choice. We assist you in gently accelerating your driven machine, owing to the hydrodynamic principle, thereby extending the life time of your system. At the same time, torque is limited, load sharing is facilitated and torsional vibrations are dampened. The coupling protects the drive system from damage even under extreme operating conditions, reducing downtime and ensuring a continuous production process.

    Furthermore, our drive solutions are reliable and specifically tailored to each drive system – from individual couplings to complete drive line solutions. The transmittable power ranges from 300 W up to 6 MW.

    Voith’s product portfolio includes constant-fill fluid couplings, fill-controlled fluid couplings, fluid couplings for diesel engines and customer-specific drive solutions.

    Constant-fill fluid couplings

      Constant-fill fluid couplings are self-contained drive components mainly used for soft start, torque limitation and dampening of torsional vibrations within the drive line. The different models vary in type and design of volumetric chambers, this determines the startup behavior.

      T – basic version

      The type T fluid coupling is the basic version of a constant-filled coupling. Such couplings are used in drives for different applications such as cranes, bucket conveyors, stackers and reclaimers. These couplings are particularly suitable if overload protection and vibration damping are required. Your drive equipment is then protected with the added benefit of increasing system productivity. This fluid coupling is also available with two work circuits (type DT). The parallel acting circuits double the power transmission.

       

      Additionally, Voith also offers fluid couplings with water as the operating medium (type TW). This is critical when operations are located in potentially explosive atmospheres. Furthermore, spheroidal cast iron outer casings (type TU) are available and meet the required material specifications.

      TV – with delay chamber

      The type TV fluid coupling is comparable to the type T fluid coupling, however enhanced with a delay chamber. When starting up, torque is reduced, enabling the driven machine to start gently. The coupling also protects the drive against overload and dampens torsional vibrations, thereby protecting your system and increasing productivity. The type TV fluid coupling is predominantly used in drive conveyors and in crushing and shredding machine applications. This fluid coupling is also available with two coaxially arranged work circuits (type DTV); the parallel acting circuits double the power transmission.

       

      Additionally, Voith offers fluid couplings with water as the operating medium (type TWV). This is critical when operations are located in potentially explosive atmospheres. Furthermore, spheroidal cast iron outer casings (type TUV) are available and meet the required material specifications.

      TVV – with enlarged delay chamber

      The type TVV fluid coupling is comparable to the type TV fluid coupling; however, it is enhanced with an enlarged delay chamber. When starting up, there is much less operating fluid in the working circuit. The driven machine starts up more gently, and the torque limitation behavior is significantly stronger during the startup. The coupling also protects the drive against overload and dampens torsional vibration, protecting your system and increasing productivity.


      The type TVV fluid coupling is predominantly used in conveyor drives (e.g., belt conveyors and plate conveyors) and in shredding machine applications. This fluid coupling is also available with two working circuits (type DTVV); the parallel acting circuits double the power transmission.

      Furthermore, Voith offers fluid couplings with water as the operating medium (type TWVV). This is critical when operations are located in potentially explosive atmospheres. Furthermore, spheroidal cast iron outer casings (type TUVV) are available and meet relevant material requirements.

      TVS – with delay chamber and annular chamber

      The type TVS fluid coupling is comparable to the fluid coupling type TV, however enhanced with an annular chamber. This results in more operating fluid in the coupling. A high thermal capacity facilitates higher starting frequencies and reversing operations in addition to protecting the drive against overload and dampening its torsional vibrations. This protects your system and increases its productivity. The type TVS fluid coupling is used primarily in crusher drives.

       

      Additionally, Voith offers fluid couplings with water as the operating medium (type TWVS). This is critical when operations are located in potentially explosive atmospheres.

      TVVS – with enlarged delay chamber and annular chamber

      The type TVVS fluid coupling is comparable to the type TVV fluid coupling, although enhanced with an annular chamber. When idling, the fluid levels in the delay chamber, working circuit and annular chamber are identical. The driven machine starts up extremely gently, and the increase in torque is dependent upon the load. The coupling also provides the drive protection against overload and dampens torsional vibrations. This protects your system and increases its productivity. The type TVVS fluid coupling is predominantly used in belt conveyor drives.

       

      Additionally, Voith offers fluid couplings with water as the operating medium (type TWVVS). This is critical when operations are located in potentially explosive atmospheres.

      TV..F – with centrifugal valves

      The type TV..F fluid coupling is a constant-filled coupling used in armored face conveyors, transfer conveyors and crusher drives. Centrifugal valves control the filling and draining of the working circuit of the coupling and thus the power transmission. The motor starts up almost load-free, even in the event of a voltage drop. The coupling torque is released shock-free and continuously, until the required breakaway torque of the system is built up. This permits overloaded driven machines to be started up. The driven machine starts extremely gently, and the increase in torque is dependent upon the load. The coupling also protects the drive against overload and dampens torsional vibration, protecting your system and increasing its productivity.


      Additionally, Voith offers fluid couplings with water as the operating medium (type TWV..F).This is critical when operations are located in potentially explosive atmospheres. Furthermore, spheroidal cast iron outer casings (type TUV..F) are available and meet the required material specifications.

      Benefits and uses

      • Load-free motor run-up
      • Smooth startup of driven machine
      • Drive overload protection
      • Dampens torsional vibration in the drive
      • Automatic reaction to voltage drops and motor protection
      • Protects system components, thereby increasing service life
      • Robust and unsusceptible to environmental influences
      • Wear-free power transmission; less maintenance and repair work
      • Automatic load sharing in multi-motor drives protects against motor overload
      • Sequential startup of the motors reduces the load on the supply circuit

      TV..Y – with refilling holes

      The type TV..Y fluid coupling is a constant-filled coupling that is used in centrifugal load drives (e.g., fan and mill applications). Thanks to the dynamic re-filling, the operating fluid is guided from the working circuit into the delay chamber during startup, depending on the slippage. This ensures an almost time-independent torque limitation and is thus suitable for longer startup times. The coupling also protects the drive against overload and dampens torsional vibrations, protecting your system and increasing its productivity. This fluid coupling is available with two coaxially arranged work circuits (type DTV..Y); these parallel circuits double the power transmission.

       

      Additionally, Voith offers fluid couplings with water as the operating medium (type TWV..Y). This is critical when operations are located in potentially explosive atmospheres. Furthermore, spheroidal cast iron outer casings (type TUV..Y) are available and meet the required material specifications.

      Benefits and uses

      • Load-free motor run-up
      • Soft startup with temporally extended torque limitation for longer start-up times
      • Drive overload protection
      • Dampens torsional vibration in the drive
      • Protects system components, thereby increasing service life
      • Robust and unsusceptible to environmental influences
      • Wear-free power transmission; less maintenance and repair work
      • Automatic load sharing in multi-motor drives protects motor against overload
      • Sequential startup of the motors reduces the load on the supply circuit

      Thermal monitoring and switching devices

      BTM (non-contact thermal monitoring device)

      The non-contact thermal monitoring device continuously determines the temperature of the operating medium in the fluid coupling and provides an active analog signal that can be continuously monitored for safety. It can also be used for process control. The BTM is typically used on belt conveyors with long and frequent startup procedures, as well as crusher and shredder applications.

      BTS (non-contact thermal switching device)

      The BTS monitors the coupling temperature contact-free. When reaching the activation temperature, the BTS switches the motor off or triggers an alarm signal. This system is particularly suitable for applications with long startup procedures or frequently occurring overloads. Typical fields of application for the BTS are, for example, medium and long belt conveyors, crushers, hammer mills and bucket wheel excavators. The BTS Ex is available for use in potentially explosive atmospheres.

      MTS (mechanical thermal switching device)

      The MTS monitors the temperature of the coupling. When reaching the activation temperature, it switches the motor off or triggers an alarm signal. The MTS is particularly suitable for applications where thermal overloading is not very common, e.g., where start-up procedures are short and occur infrequently. The MTS is predominantly used for mixers, short belt conveyors and bucket conveyors. It is also suitable for use in potentially explosive atmospheres.

      Fill-controlled fluid couplings

        Fill-controlled fluid couplings have an external fluid circuit that is also used for cooling. Additionally, they have a very high thermal capacity, allowing longer and more frequent high load start-up procedures.

        TPKL

        The type TPKL fill-controlled fluid coupling is especially suitable for belt conveyors in rugged and tough mining industry environments. Ideal for the respective load condition of the belt, the TPKL regulates acceleration extremely gently. This protects the belt, prevents downtime and increases the service life of the system. Even very difficult start-up procedures are possible at short sequential intervals, thanks to the stand-still re-cooling. These fluid couplings ensure active load sharing in multi-motor drives.

         

        The type DTPKL has two axially arranged working circuits that operate in parallel, enabling twice as much power transmission at the same overall height. The variant (D)TPKL-R has a flatter, although longer, tank for lower shaft center line heights. The most compact design is the (D)TPKL-E, which has no oil tank of its own. The tank is situated externally or, e.g., integrated into the swing frame.

        Benefits and uses

        • Load-free motor run-up
        • Smooth startup of the driven machine – up to several minutes
        • Shorter periodic distances for subsequent starts thanks to the stand-still re-cooling
        • Drive overload protection

The CPC series coupling is designed to start your armored face conveyor in a controlled manner, even under heavily loaded conditions. The coupling provides very high thermal capacity, which allows for multiple startups. The CPC coupling significantly increases system availability resulting in the highest productivity of your system.

         

        The hydrodynamic coupling circuit is specifically designed for your chain conveyor. The coupling limits the torque in the drive chain to a defined maximum value. This protects the chains and all components against damage. The availability of the armored face conveyor increases and the maintenance costs remain low.

        The coupling works with water as a non-combustible and environmentally friendly operating medium. Moreover, water is always available underground. No additional and cost-intensive explosion protection measures are necessary when installing this coupling.

        DTPKWL2

        The fill-controlled fluid coupling, type DTPKWL2, is especially suited for heavy-duty usage in armored face conveyors. In underground coal mines, this coupling provides an optimal startup as well as operational control of the armored face conveyor. Additionally, the high thermal capacity allows for multiple startups even when heavily laden.

         

        The coupling's hydrodynamic circuit is specially designed for chain conveyors, as it limits the torque in the drivetrain to a fixed value. This protects the chain and all the drive components from damage, thereby increasing the availability and productivity of the armored face conveyor while keeping maintenance costs low.

        Furthermore, the coupling operates with water. As a non-combustible and environmentally-friendly operating medium, the coupling requires no additional costly explosion protection measures. Moreover, water is also readily available underground.

          Operating principle

            The hydrodynamic principle

            Hydrodynamic couplings transmit mechanical power from the motor to the driven machine via a flow of fluid. This arises from two bladed wheels being positioned face to face. The primary wheel (red) is connected with the motor and acts like a rotary pump, while the secondary wheel (blue) is connected to the driven machine and acts like a turbine. Power transmission is proportional to the fill level in the working circuit. As a result of the mechanical separation of the drive and driven sides, the hydrodynamic coupling transfers the power wear-free and dampens the torsional vibration and torque shocks in the drive chain simultaneously.
