Abstract

A torque limiter comprises input and output shafts connected together by a clutch which disengages to prevent excessive torque from being applied to the output shaft and to allow the input shaft to rotate freely. As the clutch disengages, a brake is applied to the output shaft to prevent it from rotating. When the brake is applied, a latch holds the brake on. The clutch comprises balls which are held in clutch plate recesses to transmit torque but which ride out of the recesses and fall into pockets so that the clutch becomes permanently disengaged.
