ABSTRACT:
A gearless speed reducer or increaser consists of an input shaft, an output shaft, and a motor connected to the input shaft. There is an external race connected to one of the shafts, and an internal race attached to the other shaft. Two ball bearings are disposed between the races. After the ball bearings have been inserted, the shafts are tilted relative to each other so that the balls become fixed in pockets created between the races and cannot slide within the races. Rotating one of the shafts thus rotates the other shaft, since the balls do not slip but only rotate between the races. The system acts as a speed reducer or increaser due to the different diameters of the inner and outer races. The system can be uncoupled by pivoting the shafts back into alignment so that the balls can slide freely within the races.
