ABSTRACT:
A bent-axis hydraulic apparatus having a case in which a rotatable cylinder block is positioned and which is associated with a rotatable shaft at a drive angle therebetween. A split angle spline drive interconnects the cylinder block of the hydraulic axial piston unit with a rotatable shaft for transmission of torque therebetween without any side loading on the pistons of the axial piston unit. The split angle spline drive has two series of external teeth associated one with the cylinder block and the other with the rotatable shaft which individually mesh at two locations opposite the axis of rotation thereof with two spaced-apart sets of internal teeth on a ring gear that is rotatably-mounted in fixed location within the case of the hydraulic apparatus. The tooth mesh center lines are equally spaced from the pivot point for the cylinder block and the rotatable shaft to achieve synchronization.
