ABSTRACT:
A reduction gear comprises a parallelepiped-shaped casing containing a double worm input shaft engaging with two pinions. The input shaft has its worm portions of equal pitch magnitude but of opposite hand and the engaging pinions are one on each side of the shaft. Alternative positions are provided for the two pinions to enable the direction of rotation of the output shaft to be reversed. Each pinion carries an integral spur gear engaging a common ring gear on which the output shaft is carried. There is a square cover to the casing of the reduction gear and this cover has three bosses for use in mounting the reduction gear on a support frame.
