AXIAL-PISTON HYDRAULIC MACHINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: drive shaft flange is pivotally connected to pistons mounted in a cylinder block in a case on a bearing assembly which has two cone bearings. An additional support is made in the form of a cone bearing and is located on the side of the drive end of the shaft. An axial load distributing unit is made in the form of a bush with two shoulders one of which supports the outer race of the bearing in which a working cavity is formed and is filled with a hydroplastic and closed by concentric ring pistons. The pistons are mounted for engagement with the wide end of the cone bearing by the ends, the cone bearing is located in a cup on the side of the drive end of the shaft, and with the wide end of the outer race of the cone bearing on the side of the flange by the cup. The outer race of the cone bearing has a thrust shoulder to form between it and the bush shoulder a closed support filled with the hydroplastic and communicated with the working cavity of the distributing unit. EFFECT: improved structure. 2 dwg
