ABSTRACT:
A novel motor and method for converting rotary input motion to axial reciprocating motion of an output shaft in which input work and energy are transferred by creating unbalanced reaction forces with a motor driven unbalanced rotating mass as it acts on a pair of first pistons in direct communication with hydraulic fluid. The reaction forces created by the spinning unbalanced mass are converted to axial reciprocating motion by constraining the motion of the mass drive shaft, the supporting structure and the first pistons. A pair of second pistons, being integral with an output shaft, transfers oscillating pulses from the first pistons to a common output shaft where it can be applied to do work on an external system. Variation of motor speed provides a method of tuning the angular velocity of the unbalanced mass to match the system's nature frequency or multiples of that, thereby enhancing the system's vibration and constrained axial displacement, and resulting in enhanced input to the hydraulic first piston assemblies and output to the output shaft.
