Hydrodynamic couplings

Type T fluid coupling is the basic version of 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. This fluid coupling is also available with two work circuits (type DT). The parallel-acting circuits double the power transmission. Your drive equipment is then protected with the added benefit of increasing system productivity.

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

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 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.

When starting up, the working circuit has much less operating fluid. 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 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. Again, spheroidal cast iron outer casings (type TUVV) are available and meet relevant material requirements..

The type TVS fluid coupling is comparable to the fluid coupling type TV; however, enhanced with an annular chamber which results in more operating fluid in the coupling. A high thermal capacity facilitates higher starting frequencies and reversing operations, safeguarding the drive against overload and dampening its torsional vibrations, thus protecting your system and increasing 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. Furthermore, spheroidal cast iron outer casings (type TUVS) are available and meet the required material specifications.

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 exceptionally gently, and the torque increase depends upon the load. Protecting your system while increasing its productivity, the coupling also provides drive protection against overload and dampens torsional vibrations. 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. Furthermore, spheroidal cast iron outer casings (type TUVVS) are available and meet the required material specifications.

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 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 achieved. This permits overloaded-driven machines to be started up exceptionally gently, and the increase in torque depends on the load. The coupling also protects the drive against overload and dampens torsional vibration, protecting your system and increasing 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

The type TV..Y fluid coupling is a constant-filled coupling used in centrifugal load drives (e.g., fan and mill applications). Through dynamic re-filling, the operating fluid is guided from the working circuit into the delay chamber during startup, depending on the slippage, ensuring 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 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.

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

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 lengthy 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. For use in potentially explosive atmospheres, the BTS Ex is available.

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.

With double the power transmission capability within the same installation space, the Voith TurboBelt TPXL coupling family is specifically designed to meet the requirements of belt conveyor drives. The TurboBelt TPXL coupling provides smooth and wear-free power transmission thanks to the hydrodynamic principle. Its compact design facilitates ease of installation. Rugged, robust, and compact, the TurboBelt TPXL couplings are engineered to the highest standards for greater availability and reliable operation.

The type CPC fill-controlled fluid couplings are particularly suitable for heavy-duty underground mining use in armored face conveyors and have a power transmission range of up to 1,600 kW. Designed to start your armored face conveyor in a controlled manner, even under heavily loaded conditions, the coupling has a very high thermal capacity, that allows for multiple startups. The innovative XL wheel profile enables the coupling to transfer up to 60% more power in the same installation space, resulting in increased system availability with the highest system productivity.

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, which protects the chains and all components against damage. Furthermore, the availability of the armored face conveyor increases and the maintenance costs remain low.

The coupling operates 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.

The type TP fill-controlled fluid coupling is predominantly used in shredding machine drives. The filling level of the coupling can be controlled, allowing load-free motor run-up and controlling of the torque. Thanks to the hydrodynamic principle, the fluid coupling dampens torsional vibration and torque shocks, thus protecting the drive and increasing the productivity of your system. Due to the active cooling circuit, the TP fluid coupling has a high thermal capacity. This facilitates a smoother startup and acceleration of the driven machine over a longer period of time. Additionally, this fluid coupling is available with two axially arranged working circuits (type DTP); these parallel acting circuits double the power transmission.
 

For type TPW, the operating medium is water, which makes this coupling especially suitable for use in potentially explosive atmospheres.

The TD constant-fill fluid coupling is used in tractors to dampen drive chain torsional vibration and torque shocks, which increases the service life of all drive components. In the event of overload, the torque limiting properties of the coupling prevent the engine from stalling.

The type TDM-SAE constant-fill fluid coupling is used in diesel engine drives for mobile shredding machines. The coupling is suitable for accelerating moderate masses. Thanks to the hydrodynamic principle, the fluid coupling dampens torsional vibration and protects the drive components against overload, which increases the productivity of your system.

The types TPD-SAE and TPKD-SAE fill-controlled fluid couplings are suitable for accelerating hefty masses with high break-away torques, usually mobile shredding and crushing machines with integrated diesel engines. The filling level for these couplings is controllable, allowing load-free engine run-up and control of the torque.

 
Once emptied, the torque transmission of the fluid coupling from the engine to the driven machine is de-coupled (hydrodynamic clutching function). Furthermore, the hydrodynamic principle facilitates torsional vibration dampening that protects the drive chain against overload, increasing your equipment's productivity.
