Abstract:
A torque limiter with a rotatable housing having a series of dowels arranged annularly about an interior surface thereof and a sleeve having a pair of arms with a roller at the tip of each arm. The rollers are mounted to engage pairs of adjacent dowels selectively for transmitting torque from the housing to the sleeve. A lock-out mechanism disengages the rollers and dowels when a preset torque limit setting is exceeded by torsional resistance of the sleeve relative to the housing.
