STUDY REGARDING THE KINEMATIC AND FUNCTIONAL ASPECTS OF GLOBOIDAL WORM GEAR

Roland NINACS, A. Felicia CRISTEA, Simion HARAGÂŞ

Abstract


The unconventional worm gears are an alternative variant to conventional worm gears. Their main advantages are the high efficiency and the possibility of precise positioning (by canceling the axial clearence). Nonconventional worm gears with bearings have a shape and geometry similar to the globoidal worm gear. The kinematic analysis of the globoidal gear carried out in this paper will be used later for the kinematic analysis of the nonconventional worm gear with bearings.
