ABSTRACT:
A worm reduction gear has a casing formed by a pair of tubes oriented at right angles between another and respectively receiving a wormwheel shaft and a wormshaft. In the tube receiving the wormwheel shaft, the wormwheel is flanked by a pair of bearings held by respective bushings prevented from axial displacement by C-clips received in respective grooves adjacent the respective end of that tube. The worm on the wormshaft meshing with the wormwheel is also supported by bearings in the respective tube and at one end of one tube, at least, and preferably an end of the tube receiving the wormwheel, a flange is formed.
