Abstract
An axial piston pump provided with a pump shaft, a pump cylinder, pistons and a swashplate is stored in the inside of first and second case halves and connected to a valve plate by bolts. A tensile force is made to act on the bolts by transmitting a hydraulic pressure reaction received by the cylinder to the second case half through the valve plate and by transmitting a hydraulic pressure reaction received by the pistons to the first case half through the pump swashplate 32. The tensile force is canceled by generating a thrust force in the pump shaft 10 by meshing a helical gear 50 provided on the pump shaft 10 with a helical gear 49 supported on the valve plate 27, and transmitting this thrust force from the ball bearing 46 to the first case half 42. Thus, it is possible to reduce a tensile force which acts on the casing of an axial piston machine.
