Automatic railway coupling 422 TVVS

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. Benefits and uses Load-free motor run-up Gentle startup of the belt conveyor – up to 45s 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 against motor overload Sequential startup of the motors reduces the load on the supply circuit Automatic adjustment to the load condition of the belt through extended torque build-up
