ABSTRACT:
An apparatus is provided for limiting the relative rotation between coaxial shafts, including a helical thread about one of the shafts, a nut having a follower received in the helical thread, a spline connection between the nut and other shaft, and means for limiting axial motion of the nut when the shafts are at a selected limit of relative rotation. The follower has a large finger supporting a small finger, and the one shaft has a middle section radially spaced farther from the other shaft than the end sections. The helical thread receives only the small finger along the shaft middle section, and receives the large finger in the shaft end sections when the shafts reach the selected limit of relative rotation. The helical thread about the shaft end sections has a larger lead angle than the thread about the middle section.
