Standard Disc Spring Torque Limiters

During normal running, torque is continuously transmitted from the hub to the flange through balls or rollers held in indentations in matching halves of a carrier flange by disc springs. As the torque exceeds a pre-set limit, the balls or rollers are forced out of their indentations, allowing the flange sections to rotate separately. At this point, the torque being transmitted is negligible, and a limit switch is activated to signal an emergency stop of the motor. In Quick Guard, version re-engagement is automatic once the torque has fallen below the pre-set value. Synchronous versions also re-engage automatically after one full revolution has been completed. In the Continuous version, the rollers are prevented from fully disengaging, and a switch is activated to signal motor stop. The Free Running version also disengages the drive at a pre-set torque value but must be manually re-set to re-engage the drive.
