ABSTRACT:
An apparatus is provided for limiting the relative rotation between two drive members, including a differential having two input gears associated with the drive members, a carrier, and two coaxial differential gears carried by the carrier. One differential gear directly engages both input gears, while the other differential gear engages both input gears through idler gears. A threaded shaft is coaxially fixed to one of the differential gears and has a traveling nut thereon. A tubular shaft coaxially fixed to the other differential gear extends over the threaded shaft and has a spline connection with the traveling nut. Radially extending stops are provided on the threaded shaft and are adapted to engage axially extending tabs on the traveling nut when the drive members reach either selected limit of relative rotation.
