TOOTHED GEARING WITH PROFILE-MODIFIED HEADS OF TEETH

摘要

A toothed gearing comprises pinion and wheel with involute straight teeth placed on those, these are in engagement one with another. Teeth of the pinion and the wheel are arranged as profile-modified, due to that at sections of heads of teeth of pinion and wheel that are at distance from the tops of the teeth h≤ 0.5m involute curves of side profiles of the teeth are changed to straight lines arranged with respect to tangent lines that go through points of transition of involute curves to those straight lines at angle α&phis; = 0.25°...2.5°, where m – module of engagement.
