DESIGN AND OPTIMAL MODELING OF UNCONVENTIONAL WORM GEAR WITH BEARINGS

Roland NINACS, Simion HARAGÂȘ

Abstract


The unconventional worm gear, with bearing teeth on worm wheel, is make possible to transform sliding friction to rolling friction. Study and design is important taking into account of the fact that the energy losses at classic worm gear is high. In this study is presented design of unconventional worm gear based on the studies carried out on it. Therefore, the major changes realized, comparing to globoidal worm gear, are: replacing the teeth on worm wheel with bearings, implicit helix of the worm is made in such a way to allow bearings rotation and movement along the helix. Thus by elimination of sliding friction force it change important parameters of transmission: lower working temperature, reduce the backslash, increased operating time.
