METHOD OF PRODUCING MECHANISM FOR CONVERTING ROTATIONAL MOTION TO LINEAR MOTION AND JIG FOR EXECUTING THE METHOD

摘要

In a method of producing a mechanism for converting rotational motion into linear motion, a state in which a sun screw and planetary screws are meshed with each other with planetary shaft bodies equidistantly arranged around a sun shaft body is defined as a normally assembled state, and an assembly formed by a combination of the sun shaft body and planetary shaft bodies in the normally assembled state is defined as a first assembly. The first assembly is assembled together, with a relationship of the planetary shaft bodies relative to the sun shaft body matched with a relationship, in the normally assembled state, of the planetary shaft bodies relative to the sun shaft body.
