Speed Reducer

A cone-in-cone concept is utilized for a speed reducer, in order to substantially reduce costs and the control of critical tolerances.

A motor drive shaft 1 is connected to an inner race 2. Ball bearings 4 are maintained between race 2 and stationary outer race 3 by a resilient bearing guide 5, connected to inner race 6 of the second stage of the speed reducer. Ball bearings 8 are maintained between race 6 and outer race 7 by a resilient bearing guide 9, which is connectable to an output shaft 10. With this arrangement, critical tolerances are controlled, when required, by translating shaft 1 in either the right or left direction, for increasing or decreasing the force applied to each of the elements making up the speed reducer. Therefore, critical tolerance adjustments are not required during manufacture, thus reducing costs.
