Abstract:
A clutch mechanism for coupling and uncoupling an electric motor and leadscrew has dog-clutch gears that can be engaged by a linear actuator, bell crank, and linkage shaft. Uncoupling force due to narrowed dog teeth are resisted by the alignment of the linkage shaft with the central portion of the bell crank.
