Abstract
An axial piston machine of the inclined axis type is operable as a pump or motor has a drive shaft, a drive plate rotatable with the drive shaft, a machine housing, a drum having cylindrical bores inclined to the axis of rotation of the drive plate, pistons reciprocally mounted in the bores and connected to the drive plate, and an axial slide bearing and a radial slide bearing arranged in the housing to provide axial and radial support for the drive plate, in which an improved radial slide bearing comprises a circumferentially spaced arrangement of pressure chambers formed in the outer periphery of the drive plate each corresponding to a respective one of the cylindrical bores, the pressure chamber opening outwardly of the drive plate to form a hydrostatic and a hydrodynamic radial slide bearing with an adjacent internal bearing surface of the housing. Each pressure chamber communicates with a respective cylindrical bore and receives a supply of the operating medium of the machine, and is angularly displaced relative to the cylindrical bores so as to follow or precede the cylindrical bore with respect to the direction of rotation of the drive plate in pump operation or in motor ope…
