Fluid coupling type TDM-SAE
The constant-filled fluid coupling type TDM-SAE is used in drives for diesel engines for mobile shredding machines. The coupling is suitable for accelerating moderate masses. Thanks to the hydrodynamic principle, the fluid coupling dampens torsional vibration and protects the drive components against overload. This increases the productivity of your system.

Typical fields of use
Dimensions in mm
The fluid coupling TDM-SAE is flanged directly to the motor.
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 are self-contained drive components. The different types of constant-filled couplings are mainly differentiated by the additional chambers , where their automatically controlled fill and emptying have a decisive influence upon start-up behavior. The demand of the drive technology determines the coupling type and capacity. Constant-filled couplings are mainly used for soft start , torque limitation control and influencing the torsional vibration behavior of the drive .
