PROBLEM TO BE SOLVED: To develop a gear requiring no back lash, and a gear drive compressor. SOLUTION: In this gear drive compressor, a significant number of male teeth (projections) are parabolically arranged on a driven side cylinder outer face sliding an outer face of a stationary cylindrical compression cylinder, and rotary-engaged with cut-type female teeth on the outer periphery of a drive side gear plate, so as to transmit a drive force. In response to transmission of the drive force, the driven side cylinder performs regression motion. A rotary disc is installed at an inner central portion of the regression motion cylinder. There is provided with a mechanism for converting a regression movement into a reciprocating piston movement in combination of a rotation-free rotary disc, a presser ring, a square piston, and a square bearing, to be used as a drive source of a compressor, a pump, and the like. Development of a gear requiring no backlash can obtain an inexpensive gear with little noise and vibration, and with simplified manufacture and reduced price. COPYRIGHT: (C)2005,JPO&NCIPI
