Abstract
A support for the drive shaft of an axial-piston machine of inclined axis construction (pivoted or tilted drum) for pressurized fluids, consisting of at least one axially loadable bearing arranged at respectively, the piston side and at the drive side with stationary outer rings arranged in a bearing housing and a load-receiving direction located the same towards the piston side. At least the outer ring of one of the bearings is axially supported on the bearing housing and at least one of the inner rings of the bearing is supported on the drive shaft at the piston side shaft and whereby, for balancing the axial components of the piston forces effective between the bearings, there is provided at least one pressure cylinder unit with a balancing piston which is acted upon with pressurized fluid from the pressure side of the machine.
