THE UNIQUE CIRCULUTE TEETH REDUCER'S power train sets it apart from other speed reducers. The New Series of high efficiency, performance, and compactness have been accomplished.

Operating principles

Shimpo CORONET reducers are quite different from ordinary planetary gear systems.
･One tooth less than the number of internal pins, and inner epicyclic gear mechanism.
･"Circulute tooth profile and inner contact mechanism"

1. When the input shaft (motor shaft) makes one rotation, the eccentric roller bearings also rotate once in the same direction.
2. The Circulute wheel, which is assembled to the eccentric motion, with its Circulute teeth gearing consecutively on the internal pins.
3. As fig. D shows, when the eccentric roller bearing has completed one full rotation, that is to say when the Circulute wheel has completed one full revolution the Circulute tooth initially in mesh at some point will come to mesh as many teeth behind the initial point as there is difference between the number of Circulute teeth and internal pins. This means the Circulute wheel has rev
4. This rotational motion of the Circulute wheel about its own axis is transmitted to the output shaft through the carrier pins.
