Abstract
A shaft arrangement for an axial piston pump assembly to couple to a rotatable member such as a gear therewith. A shaft extends at least partially through a housing chamber of the pump about a longitudinal axis. Reciprocating pistons are disposed within the chamber radially about the shaft. A cam unit is fitted over the shaft and provides an angled camming surface to engage the pistons. Bearing assemblies are fitted over the cam unit. An adapter can be fitted over the proximal end of the cam unit. The adapter has a distal surface which may abut the bearing assembly and be axially spaced from the cam unit, and an outer radial surface to engage the rotatable member. A clamping device provides a desired clamp load path between the rotatable member, the adapter, the cam unit, the bearing assemblies and the shaft.
