Abstract:
Axial piston machine, preferably of swash plate construction, having a revolving cylinder drum (3) arranged on a drive shaft (10) and working pistons (5) supported via slippers (6) on a swash plate (7), which may be adjustable in its tilt angle, in which machine the housing inner chamber (20 of the pump housing (1) filled with leakage operating medium is bounded by a roller bearing (11) by means of which the drive shaft (10) is mounted in the pump housing (1), whereby a shaft sealing arrangement (12) is arranged outside the roller bearing (11), and in which machine a device for conveying operating medium through the bearing gap of the roller bearing (11) is provided, characterized in that, there is provided before the bearing gap of the roller bearing (11), on the side towards the housing inner chamber (2), a conveyor plate (15) revolving with the drive shaft (10), which plate urges operating medium through the bearing gap into an annular space (17) between roller bearing (11) and shaft sealing arrangement (12) and in that the annular space (17) is connected with the housing inner chamber (2) through a discharge channel (18m 19), the roller bearing (11) has an inner bearing ring (22) which is axially fixed, at least on one side, to the drive shaft (10) by way of the conveyor plate (15) and a securing, means (21) engaging on the conveyor plate (15) on the side away from the roller bearing (11) whereby the conveyor plate (15), arranged between the inner bearing ring (22) and the securing means (21), serves as a compensating slate which can be adjusted in its axial dimension for compensation of the manufacturing tolerances which determine the axial seat of the inner bearing ring (22).
