The MS synchronous coupling from RENK-MAAG GmbH provides a form-fit connection – similar to a flexible coupling – between synchronously-rotating system parts and automatically separates at non-synchronous speeds. The coupling is wear-free due to the hydrodynamic lubrication of all components. The synchronizing mechanism is also relieved by the helical design of the load toothing. The coupling functions like a flexible coupling and can compensate for large axial displacements, radial misalignments, or angular errors.

As soon as the input speed falls lower than the output speed, for example when shutting down a combined power plant, the coupling is automatically separated without wear due to the helical toothing – and all at an extremely low vibration level.

When disengaged, the MS clutch generates negligible drag torques and can ensure the safe separation of the system due to additionally integrated components. This makes it possible to carry out maintenance tasks in switched off areas of the system and thereby keep production downtimes at a low level.
