Hydraulic pump or motor with mounting configuration for increased torque

A hydraulic pump or motor with a mounting configuration for increased torque comprising:

• a shaft defining a longitudinal axis, a Y-axis extending upwardly and orthogonally from the longitudinal axis, and an X-axis extending orthogonally to the longitudinal axis, and the Y-axis;
• a housing defining a first longitudinal end, a second longitudinal end, and a cavity that extends from the first longitudinal end to the second longitudinal end;
• a plurality of mechanical components including one hydraulic interacting components that are disposed in the cavity;
• and
• a manifold cap attached to the second longitudinal end that defines an inlet and an outlet;
• wherein the shaft extends from the cavity past the first longitudinal end of the housing, and a mounting flange is disposed at the first longitudinal end of the housing, the mounting flange defining a pair of bolt receiving slots that are disposed along the X-axis on either side of the shaft, the pair of bolt receiving slots each define a radius center that are spaced away from each other a X dimension, and a Y-dimension that defines a width of the slot, and a ratio of the X-dimension to the Y-dimension ranges from 9.5 to 9.8.

A hydraulic fan pump assembly comprising:

• a shaft defining a longitudinal axis, a Y-axis extending upwardly and orthogonally from the longitudinal axis, and an X-axis extending orthogonally to the longitudinal axis, and the Y-axis;
• a housing defining a first longitudinal end, a second longitudinal end, and a cavity that extends from the first longitudinal end to the second longitudinal end;
• a plurality of mechanical components including at least one hydraulic driven component that are disposed in the cavity;
• and
• a manifold cap attached to the second longitudinal end that defines an inlet and an outlet;
• wherein the shaft extends from the cavity past the first longitudinal end of the housing, and a mounting flange is disposed at the first longitudinal end of the housing, the mounting flange defining a pair of bolt receiving slots that are disposed along the X-axis on either side of the shaft, the pair of bolt receiving slots each define a radius center that are spaced away from each other a X dimension, and a pilot projection that extends longitudinally away from the mounting flange, defining a pilot projection diameter, and a ratio of the X dimension to the pilot projection diameter ranges from 1.1 to 1.5.
