Worm gear |
摘要 |
A worm gear has a threaded spindle and a threaded nut, the thread on the spindle or the nut or on both having a profile such that the transition regions connecting the thread crown surface to the thread flanks are rounded, as is the crown surface itself. Further, the spindle thread and nut thread are intermeshed with axial and radial play such that radial forces exerted under torque loading are transmitted only by areas of the crown surface, which transmitted forces are supported by the respective areas of the opposing groove bottom. Smooth functioning is ensured even when the threaded spindle occupies a position of maximum inclination relative to the nut.
