ABSTRACT:
The gear reduction system is of the differential type utilizing two ring gears with teeth on their inner circumference and first and second eccentric wheels having external teeth engaging the teeth on the ring gears as they roll about the inner circumference. The first and second wheels have their eccentricities mounted in an offset relationship so as to provide dynamic balancing during operation. By making the number of teeth on one of the eccentric wheels different from the number of teeth on the other, adding the second ring gear and providing appropriate pin carrier means coupled in a given arrangement, a very high gear reduction can be achieved in a single packaging. This gear reduction is equivalent to that heretofore only obtainable by ganging together separate reduction gear systems of this type.
