Abstract

The gear reducer has a wheel (1) fitted with a member of equally spaced grooves around the rim of the wheel. The grooves are separated from each other and cross the thickness of the wheel. The drive gear has a shaft perpendicular to the wheel spindle. The shaft carries a bush (2) fitted with a continuous helical groove. The ends of the groove are joined internally by a bore (6) guided across the wheel. The ends of the bush are closed by flanges (4) and the bush runs inside a casing (3). As the shaft rotates, the wheel is caused to rotate and the balls travel along the continuous groove.
