Drive Assembly for a Rotary Fluid Pressure Device

摘要

A rotary fluid pressure device includes a housing section defining an inlet port and a return port. A valving assembly is in fluid communication with the inlet port and the return port. A first fluid meter defines a plurality of volume chambers that are in fluid communication with the valving assembly. A second fluid meter defines a second plurality of volume chambers in selective fluid communication with the valving assembly. A drive assembly is engaged with the first fluid meter and the second fluid meter. The drive assembly has a drive shaft and a drive collar. The drive shaft has a first axial end portion engaged with the first fluid meter and an oppositely disposed second axial end portion, the drive collar is removably coupled to the second axial end portion of the drive shaft. The drive collar is engaged with the second fluid meter.

主权项

1. A rotary fluid pressure device comprising:
a housing section defining an inlet port and a return port; a valving assembly being in fluid communication with the inlet port and the return port; a first fluid meter having a ring and a star defining a plurality of expanding and contracting volume chambers, wherein the volume chambers are in fluid communication with the valving assembly; a second fluid meter having a ring and a star cooperatively defining a second plurality of expanding and contracting volume chambers, wherein the volume chambers are in selective fluid communication with the valving assembly; and a drive assembly engaged with the first fluid meter and the second fluid meter, the drive assembly having a drive shaft and a drive collar, the drive shaft having a first axial end portion engaged with the star of the first fluid meter and an oppositely disposed second axial end portion, the drive collar being removably coupled to the second axial end portion of the drive shaft, the drive collar engaged with the star of the second fluid meter.
