Abstract:
A hydraulic pump unit includes a cylindrical member that is fit into an outer circumference of the main shaft and a hydraulic pump body arranged on an outer circumferential side of the cylindrical member. The hydraulic pump body includes a ring cam mounted on the outer circumference of the cylindrical member, a pump bearing, a pump housing, a plurality of pistons housed in the pump housing and actuated by the ring cam, and a plurality of cylinders which guide the plurality of pistons in a radial direction and are arranged in a circumferential direction. The hydraulic pump unit is configured such that the pump unit is insertably fixed to the main shaft by the cylindrical member.
