6. Operating Principles The reducer portion of the FINE CYCLO® is fundamentaly different in principle and mechanism from the involute gearing mechanism of competitive gearmotors. The unique speed reducer portion is an ingenious combination of the following two mechanisms: A combination of a planet gear and a fixed internal sun gear. In the FINE CYCLO®, the planet gear has cycloidal-shaped teeth and the sun gear has circular pin teeth. The number of teeth in the planet gear is one or two less than the sun gear. A constant speed internal gearing mechanism. Principle of internal Planetary...
