Torque Blocker
Protects connected machinery against extreme torque overloads by disconnecting shafts — allowing machines to coast down independently.
Product Overview
The Torque Blocker is a coupling solution that protects connected machinery against extreme torque overloads by mechanically disconnecting the drive and driven shafts when a set torque threshold is exceeded. Once disconnected, both machines are free to coast down independently — providing a gentle, controlled post-event landing rather than a hard stop.
This approach protects both the drive machine (turbine or motor) and the driven machine (compressor or generator) from the damage that would result from a locked-rotor or extreme torque event. The Torque Blocker is designed to be reset and returned to service, minimizing downtime after a trip event.
