TVVS couplings from Voith Turbo-Perfectly smooth start-ups
Fluid couplings from voith turbo have proven themselves in millions of applications. They are operating reliably all over the world. Based on our comprehensive experience and close co-operation with our customers, the TVVS coupling was developed a genuine “ soft start” device, highly suitable for demanding drives in the material handling and processing industry
The Voith Turbo TVVS fluid coupling provides outstanding characteristics, such as excellent limitation of start-up torques, as well as automatic adaptation of the maximum transmittable torque to the prevailing load. For belt conveyors, the stresses on the belt are significantly reduced. Other benefits: higher service life of the system, as well as low maintenance costs and downtime.
The Advantages of TVVS soft-start couplings in belt conveyor drives :
- Load-free run-up of motor
- Smooth acceleration
- Alleviation of undesirable start-up conditions (such as lifting of belt, longitudinal vibrations, etc)
- Automatic adaptation of starting torque to prevailing load situation
- Limitation of starting torque
- Higher service life of belt and other conveyor drive components
- Utilization of economically priced, low-maintenance squirrel-cage asynchronous motors
- Load sharing and step starting for multimotor drive
Powerful components for demanding drives
Classic fields of application for the TVVS are the Drives of belt conveyors with higher capacities and lengths. During the startup process, the TVVS soft start coupling ensures optimum adaption of the introduced torque to the prevailing load condition. The unique control functions of the TVVS are automatic and require no external intervention of modification of the filling level of the coupling
