Fluid coupling type T for ship drives

Fluid coupling type DTL

The Voith fluid coupling types T, TM1 and TL are constant-fill fluid couplings for ship propulsion systems. The coupling damps torsional vibrations, impacts and shocks that originate from the engine and propeller. The hydrodynamic principle permits a relieved startup of the engine. This increases the service life of all drive components.

The different types are suitable for the different requirements when integrating into the drive line, such as e.g., installed directly on the engine.

These fluid couplings are also available with two coaxially-arranged working circuits (Typ DT, DTM1 and DTL). The circuits acting in parallel increase the power transmission.

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.
