Abstract
A gear speed reducer having an input shaft formed with a worm which meshs with a worm gear mounted on an output shaft disposed a fixed distance from and at right angles with respect to the input shaft. The worm is provided with an involute thread that progressively becomes thinner from one end to the other end of the worm. An adjustable cartridge rotatably mounts one end of the shaft and the cartridge is adjustably mounted to permit axial adjustment of the shaft to bring a new section of the thread of the worm into engagement with the worm gear to eliminate backlash therebetween. The adjustment is quickly and easily performed without having to remove the reducer from service.
