Geometric Evolution of High Ratio Hypoid Gear
Journal Title: 河南科技大学学报（自然科学版） - Year 2017, Vol 38, Issue 3
Abstract
A kind of high ratio hypoid( HRH) gear with arc equal-height was proposed. The evolution of pitch cone of HRH gear and the evolutionary course of arc equal-height gear teeth in the direction of tooth height and tooth thickness were discussed. The evolutionary course of geometric characteristic of HRH gear and its key factors were analyzed. The optimization method for the design of pitch cone of equal-height HRH gear was presented. The tooth surface equation of conjugated pinion was derived from the tooth surface geometric and meshes equation of big gear. The coordinates of discrete points on tooth surface were achieved according to these equations. The three dimensional solid models and simulation of the gear teeth were performed and compared with the machined solid gears. The results prove that the proposed arc equal-height HRH gear is feasible both in theory and practice.
