Abstract

Abstract: The space surface of high reduction hypoid gear (HRH) is complex, so it is difficult to control the meshing quality of the hypoid gear by conventional machining calculation method. The coordinate system of space gear meshing transmission is established, and the general form of space meshing equation is given. The surface equation of trimming cutter head is deduced, and the tooth profile modification method of cutter head is put forward, which solves the problem of tooth surface curvature correction of HRH gear. Based on the principle of close surface, the simulation model of HRH gear machining parameters calculation and meshing was established by integrating the production surface, small wheel surface and ease-off difference surface. The geometric parameter control method of ease off difference surface and the process of HRH gear machining calculation and meshing simulation calculation are given, and the differential structure of tooth surface and meshing quality are controlled. The meshing quality of the tooth surface is tested by the contact spot and dynamic performance test. It solves the difficult problem of complex HRH tooth surface differential structure correction and meshing quality control.

Key words: bevel gear, surface synthesis, meshing equation, ease-off
