Schrägwellen-Hydraulikmaschine mit veränderlicher Verdrängung.

摘要

A bent axis type variable displacement hydraulic machine employing hydrostatic radial bearings (20;31;47) for supporting hydraulic reaction forces exerted on the cylinder block 8. In a hydraulic machine (8) of this sort, the number of pistons which (10) are located in the high pressure are varies with the rotation of the cylinder block (8), and the resultant force of hydraulic reaction forces has an acting point at a position off the axis of the rotational shaft (5;45). Therefore, the hydrostatic radial bearings (20;31;47) are located in such positions as to balance the moment loads which occur about the rotational shaft (5;45) in relation with the acting point of the resultant force of radial hydraulic reaction forces on the drive disc (6;46) of the rotational shaft (5;45). As a result, it becomes possible to lead to suppression of oil leaks from the sliding surfaces (12) to a minimal rate and to prevent abnormal abrasive wear of each of the sliding surfaces (12).
