Abstract

715,462. Toothed gearing. NIEMANN, G. May 15, 1951 [Feb. 13, 1950]. No. 3626/50. Class 80 (1) A worm wheel 1 is a cylindrical spur wheel having straight or helical teeth and the worm 2 is of globoidal form. The worm or its teeth flanks are of a softer material than the wheel teeth flanks, e.g. bronze and hardened steel, and the roots of the worm teeth are preferably thicker than those of the wheel teeth. The teeth of the wheel may be of involute or straightsided taper profile.
