[Abstract]:As a new type of gear transmission, face gear transmission has the advantages of compact structure, high transmission ratio, high coincidence degree, simple installation and easy manufacture of small wheels. In order to improve the transmission performance and meshing quality of surface gear, a new method of grinding surface gear with small wheel double drum and curved cone grinding wheel is presented in this paper. 1. The arc trajectory and parabola trajectory are studied, and the two methods of tooth surface modification are established, and the equations of tooth surface and meshing are derived. The mismatch relationship between double drum modification of small wheel and original involute tooth surface is calculated and drawn by Matlab. 2. The gear tooth contact analysis model considering the installation error is established, and the meshing characteristic of the local conjugate face gear pair is studied. Through the computer meshing simulation, the unidirectional modification of the small wheel tooth is given. Contact path and transmission error of small wheel double drum modification; The influence of different modification parameters on meshing performance of gear pair with double drum modification surface is analyzed. 3. The method of grinding orthogonal face gear with small wheel double drum forming grinding and curved cone grinding wheel is put forward. The coordinate system of grinding wheel and wheel and surface gear grinding wheel and surface gear grinding wheel are established. The axial section profile and rotary surface equation of small wheel grinding wheel and large wheel grinding wheel are derived. The dressing principle of surface gear grinding combined grinding wheel is studied. The surface gear grinding model is established. 4. According to the existing 514 gear shaper, a gear shaper machining tool is designed. The surface gear shaper is finished, and the small wheel double drum grinding experiment is carried out. The rolling test and noise test are carried out on Y9550 bevel gear roller tester. The experimental results verify the feasibility and correctness of the theoretical method of small wheel double drum modification.
