SYSTEMS AND METHODS THAT USE HARMONIC DRIVES FOR CONVERTING RECIPROCATING AXIAL MOTION TO CONTINUOUS ROTARY MOTION, HELICAL DRIVES FOR CONVERTING RECIPROCATING ROTARY MOTION TO RECIPROCATING AXIAL MOTION AND COMBINATIONS THEREOF FOR CONVERTING RECIPROCATING ROTARY MOTION TO CONTINUOUS ROTARY MOTION

A harmonic drive assembly and fluid-powered linear motors with both axial pistons are rotary piston arrangements incorporating the harmonic drive assembly are disclosed. The motors may be used in downhole drilling applications, but the drive assembly and/or motors may be used in other applications....
