ABSTRACT:
An apparatus is responsive to a reaction force of intermeshing gear members that transmit force through an angle. The gear members include an elongated enveloped worm with a longitudinally extending axis of rotation and an output gear with an axis of rotation offset from and perpendicular to the longitudinally extending axis of the worm gear. The worm gear is movable axially in response to a predetermined reaction force or predetermined torque force. At least one biasing member is disposed adjacent one end of the worm gear, and preferably both ends of the worm gear, for centering the worm gear with respect to the output gear when subjected to a force below the predetermined reaction force or predetermined torque force.
