Fluid coupling type T

The fluid coupling type T is the basic version for constant filled coupling. Such couplings are used in drives for different applications, such as, e.g., cranes, bucket conveyors, pick-up and pos­itioning devices.

This coupling is particularly suitable if overload protection and vibration damping are required. They protect your drive equipment and increase the productivity of your system.

This fluid coupling is also available with two work circuits (type DT). The parallel acting circuits double the power transmission.

We offer fluid couplings with water as the operating medium (type TW) especially for potentially explosive atmospheres or with outer casing made of spheroidal cast iron (type TU) 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 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.

Cross-section, fluid coupling type T

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.
