Voith Fluid Couplings for Diesel and Gas Engine Drives - Voith Turbo

Type TDVFM-SAE
Voith fluid couplings type TDVFM-SAE are based on type TDM-SAE.
Owing to an additional delay chamber and centrifugal valves, they
are well suited for accelerating heavy masses with high break-away
torques.

Input speed [rpm]
At the engine side, a wear­free steel diaphragm
transmits torque from the diesel
engine to the fluid coupling. At the output
side, a v­belt pulley, a cardan shaft or a
flexible connecting coupling can be added.
