Abstract
Axial retention of the drive shaft is provided in a fluid pressure device of the type including an internally-toothed member, an externally-toothed member disposed eccentrically therein for relative orbital and rotational movement, and a drive shaft extending into a central bore defined by the externally-toothed member. The drive shaft has male splines and the externally-toothed member has female splines in the central bore, engaging the male splines. The front face of the externally-toothed member has a recess including a stop surface generally perpendicular to the axis of the device and the drive shaft has a shoulder extending radially outward and engaging the stop surface to limit the axial movement of the drive shaft into the central bore. Wear is minimized because the mating stop surface and shoulder are rotating at the same speed and, preferably, the shoulder 'nutates' with respect to the stop surface.
