ABSTRACT:
The pintle shaft of a radial piston hydraulic pump-motor is cantilevered from one end frame member by guideways which permit it to be moved laterally for adjustment of the speed, torque output and direction of rotation. A reaction assembly is journaled in a second frame member by means of the input-output shaft. The reaction assembly includes two reaction rings, one on either side of the cylinder block, which rotate on bearing blocks on the pintle shaft, the bearing blocks and shaft having interengaging parallel, flat slide surfaces which permit the shaft to be translated while still being in mutually supported and stabilized relation with the reaction rings. The side loads on the pintle shaft are counteracted by friction forces developed between the slide surfaces on the bearing blocks and pintle shaft so that the pintle shaft remains stable relative to the reaction assembly without direct mechanical support of its blind end against side loads.
