Abstract
A reciprocating assembly for driving a working portion of a tool includes a body having a bore configured to contain a hydraulic fluid, and a piston received within the bore and configured to move within the bore in a reciprocating motion between an extended position and a retracted position. Displacement of the piston within the bore is configured to cause displacement of hydraulic fluid when hydraulic fluid is in the bore. An outer surface of the piston and/or an inner surface of the bore at least partially coated with a friction reducing material.

A reciprocating assembly for driving a working portion of a tool, the reciprocating assembly comprising:
- a body having a bore configured to contain a hydraulic fluid;
- and
- a piston received within the bore and configured to move within the bore in a reciprocating motion between an extended position and a retracted position, wherein displacement of the piston within the bore is configured to cause displacement of hydraulic fluid when hydraulic fluid is in the bore;
- wherein an outer surface of the piston and/or an inner surface of the bore at least partially coated with a friction reducing material.
A gear assembly for driving a working portion of a tool, the gear assembly comprising:
- a stationary ring gear;
- a central gear disposed within the inner diameter of the ring gear;
- at least one planet gear contacting both the ring gear and the central gear;
- and
- wherein at least one of the ring gear, the central gear, and the at least planet gear is at least partially coated with a friction reducing material.
A tool comprising:
- a gear assembly comprising an input gear and an output gear, wherein at least one of the input gear and the output gear are at least partially coated with a friction reducing material;
- a reciprocating assembly configured to be driven by the gear assembly, the reciprocating assembly comprising:
- a body having a bore configured to contain a hydraulic fluid;
- and
- a piston received within the bore and configured to move within the bore in a reciprocating motion between an extended position and a retracted position, wherein displacement of the piston within the bore is configured to cause displacement of hydraulic fluid when hydraulic fluid is in the bore;
- wherein an outer surface of the piston and/or an inner surface of the bore at least partially coated with a friction reducing material;
- and
- a working portion configured to be driven by the reciprocating assembly.
