Title
(EN) HYDRAULIC MACHINE COMPRISING AN IMPROVED BEARING
(FR) MACHINE HYDRAULIQUE COMPORTANT UN PALIER PERFECTIONNÉ
Abstract
(EN)
Disclosed is a hydraulic piston machine comprising a housing (100), a shaft (200) that is able to rotate relative to the housing (100), a cam (112) secured to one of the housing (100) or the shaft (200), a cylinder block (334) comprising pistons (336) that are able to move in the cylinder block (334) opposite the cam (112) in order to generate relative rotation between the cylinder block (334) and the cam (112), the cylinder block (334) being linked in rotation to the other of the shaft (200) or the housing (100), means (400) forming rotation guide bearings for guiding the rotation of the shaft (200) relative to the housing (100), in which means (400) forming rotation guide bearings comprise a tapered plain bushing (450) interposed between a housing element (116) and an element (334, 380) linked in rotation with the shaft (222) and in which the tapered plain bushing comprises a radial through-slit extending through the entire radial dimension of the bushing.
