Abstract
An hydraulic centrifugal piston motor having mulitple piston circumferentially disposed at right angle to shaft axis, having a rotational power moment that occurs twice each revolution for each cylinder. The power stroke for each cylinder would occur for a duration of 90 degrees twice during each 360 degree operating cycle. Hydraulic input is applied to opposing pairs of cylinders and overlap of successive power strokes provide rotational balance and cancels net reaction forces applied to the bearings. Another feature of the motor would be the particular design of the power transfer device. The thrust of the power transfer device is applied axially to the drive shaft providing a smooth transfer between the hydraulic input power and the mechanical output power.
Claims5
An hydraulic piston motor comprising:
- an annular cylinder block of rigidly fixed uniformity, having multiple cylinders secantly disposed on outer circumference of said cylinder block,
- means for valving hydraulic fluid into and exhausting from each individual cylinder,
- means for mounting the cylinder block to a drive shaft assembly,
- said drive shaft assembly comprising:
- a single shaft and a torque actuator assembly,
- said torque actuator assembly comprising:
- a round thrust pin with means for mounting truncated conically shaped bearing cups with needle bearings on each protruding end of said thrust pin,
- means for mounting the torque actuator assembly to the drive shaft assembly,
- means for mounting the drive shaft assembly to a housing structure,
- an annular piston rod support ring assembly comprising:
- a rod support ring of rigidly fixed uniformity, having multiple piston and rod assemblies interiorly mounted to said rod support ring, each said piston and rod assembly comprise a piston and a rod,
- means for mounting the piston and rod assemblies to the rod support ring,
- an annular thrust yoke assembly comprising:
- two similar halves, each having an arcuate mortise groove,
- means for mounting the rod support ring assembly and said thrust yoke assembly to a thrust yoke positioner assembly,
- means for mounting said thrust yoke positioner assembly to said housing structure,
- means for universal coupling and synchronizing the rotating assemblages to produce unidirectional torque axially to the output shaft.
