Abstract
Systems and methods are provided for a hydraulic axial piston assembly. The hydraulic axial piston assembly may include a distributor plate, a bearing element directly and orthogonally connected to a side of the distributor plate, and an adjustment screw orthogonally connected to the bearing element, where the adjustment screw is externally accessible and manually rotatable to adjust a timing angle of the distributor plate.
Claims19
A hydraulic axial piston assembly, comprising:
- a distributor plate;
- a bearing element directly and orthogonally connected to a side of the distributor plate;
- and
- an adjustment screw orthogonally connected to the bearing element, where the adjustment screw is externally accessible and manually rotatable to adjust a timing angle of the distributor plate, wherein the bearing element is configured to rotate around a first rotational axis and the adjustment screw is configured to rotate around a second rotational axis that is orthogonal to the first longitudinal axis.

A hydraulic axial piston assembly, comprising:
- a distributor plate configured to fluidly couple one or more cylinder bores of an axial piston system to a distributor body that includes a fluid inlet passage and a fluid outlet passage;
- and
- an eccentric bearing including a pin housed within a notch of the distributor plate and configured to rotate via rotation of an adjustment screw, wherein the eccentric bearing and adjustment screw are positioned in the distributor body and wherein the adjustment screw extends orthogonally to the eccentric bearing, wherein rotation of the adjustment screw drives rotation of the eccentric bearing around an axis of rotation orthogonal to an axis of rotation of the adjustment screw.
A hydraulic axial piston assembly, comprising:
- an axial piston system;
- a distributor body coupled to the axial piston system via a coupling surface, the distributor body including a fluid inlet passage and a fluid outlet passage, the distributor body further including a first bore extending from an external surface of the distributor body to a second bore extending to the coupling surface of the distributor body, the first bore extending along a first axis that is orthogonal to a second axis along which the second bore extends;
- and
- a distributor plate configured to fluidly couple one or more cylinder bores of the axial piston system to the fluid inlet passage and the fluid outlet passage of the distributor body, wherein the distributor plate is rotatable via an eccentric bearing including a pin housed within a notch of the distributor plate, the eccentric bearing configured to rotate via rotation of an adjustment screw, wherein the eccentric bearing is housed in the second bore and the adjustment screw is housed in the first bore.
