摘　　要：根据微分几何和啮合原理,建立了渐开螺旋面、啮合线及啮合界限线方程,利用MATLAB绘出啮合线和啮合界限线。结果表明,在工件齿轮参数给定的情况下,交错角和中心距影响啮合线和啮合界限线的分布,工作半角影响实际啮合线;满足强度要求的前提下,给定中心距即采用变位啮合传动,合理选择交错角和工作半角,可以实现全齿珩削且啮合线分布均匀无交叉现象。解决了工件螺旋角较小时,必须轴向进给;螺旋角较大时,需采用较大的中心距,才可实现全齿珩削的问题。According to the theories of differential geometry and gear meshing,the basic equations for involute helicoids,meshinglines and meshing boundary lines are deduced.Then using MATLAB program,the contact lines and meshing boundary are drawn.The results show that,under the condition of given the parameters of gear workpiece,the distribution of contact lines and meshing boundary lines are influenced by stagger angle and center distance,the actual contact lines are influenced by work half-angle.On the premise of meeting the strength requirements,giving the center distance called modified gear drive and choosing the reasonable stagger angle and half-angle,the honing full gear without axial feed and the well-distributed and uncrossed contact lines can be realized.The problem is solved that in order to realize full gear honing,the axial feed must be adopted with small helical angle and larger center distance must be adopted with large helical angle.
