Fluid coupling type TVS

The fluid coupling type TVS is equivalent to the fluid coupling type TV, enhanced with an annular chamber. This results in more operating media in the coupling. This gives the coupling a high thermal capacity and makes it suitable for higher starting frequencies and reversing operations. The coupling also protects the drive against overload and dampens torsional vibrations . This protects your system and increases its productivity.

The fluid coupling type TVS is used in drives for crushers.

We offer fluid couplings with water as the operating medium (type TWVS) especially for potentially explosive atmospheres or with outer casing made of spheroidal cast iron (type TUVS) for use in operations with relevant material requirements.

Temperature monitoring systems (MTS, BTS, BTM) increase the availability of the drive and boost the productivity of the system.

Technical information

Operating principle


         <br />
        Operating principle of the hydrodynamic power transmission
 
Operating principle of the hydrodynamic power transmission

Hydrodynamic couplings transmit mech­anical power from the motor to the driven machine via a flow of fluid. This occurs by means of two bladed wheels positioned face to face. The primary wheel (red) is connected with the motor and acts like a rotary pump, 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 couplings transfer the power wear-free and dampen the torsional vibration and torque shocks in the drive chain at the same time.

Constant-filled couplings

Constant-filled couplings are self-contained drive components. The different types of constant-filled couplings are mainly differentiated by the volumetric chambers , where their automatically controlled fill and emptying have a decisive influence upon start-up behavior. The demand of the drive application determines the coupling type and capacity. Constant-filled couplings are mainly used for soft start, torque limitation and dampening the torsional vibration behavior of the drive.

Engineering 

Voith doesn't just supply couplings, we are also your engineering partner for customer-specific drive solutions:

  • Designing of complete drives
  • Dimensioning the coupling for the optimal use of your system
  • Analysis and optimization of the operating state of drives in existing systems (retrofit)
  • We can advise you about the selection of optimal start-up technologies
  • Competence in systems for all mining equipment and the bulk material industry
