ABSTRACT:
The disclosure is directed primarily to pairs of unique nutating gears which are used for restraining the rotation of the wobbler portion of the split swash-plates of both variable- and fixed-displacement hydraulic machines in which the pistons reciprocate in fixed cylinders. Each pair consists of an internal gear fixed to the housing and an external gear fixed to the outer circumferential surface of the wobbler. Using any one of four different tooth designs, the gears simultaneously share two centers of meshing engagement when nutating, and they do not interfere with the complex lemniscate motion of the wobbler. This wobbler mounting arrangement results in significant size and weight reductions which are further enhanced by sliding shoe bearing assemblies that carry the axial loads developed by the machine's reciprocating pistons. The hydraulic machine is also provided with a modular design that makes it possible to make significant changes in displacement size with minimal changes in machine structure.
