Abstract
A jam-tolerant rotary actuator 70 through the incorporation of shear lugs 84,92 formed on an inner input sun gear member 82 and on an inner movable output ring gear member 90 which correspond to recesses 88,96 formed in an outer input sun gear member 86 and in an outer movable output ring gear member 94, respectively, where, upon application of a maximum torque to either the inner input sun gear member 82 or the outer movable output ring gear member 94, the shear lugs 84,92 will shear thereby allowing the inner input sun gear member 82 to be movable independent of the outer input sun gear member 86 or the outer movable output ring gear member 94 to be movable independent of the inner movable output ring gear member 90, respectively.
