Fluid coupling TV..F

transmissionmotormachines

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 Benefits and uses Load-free motor run-up Smooth startup of the driven machine Drive overload protection Dampens torsional vibration in the drive The 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 Typical fields of use Armored-face conveyors Stage loader Crushers
