摘要

摘要: 针对内斜齿轮数控成形磨削中较难解决的磨削干涉问题,研究了内斜齿轮成形磨削的砂轮修形方法.在建立内斜齿轮成形磨削数学模型的基础上,用截圆法得到磨削内斜齿轮时砂轮与齿槽接触点所满足的条件方程组,通过牛顿迭代法解此方程组求出砂轮廓形.用数值法模拟出所求砂轮的实际磨削齿形并与理论渐开线齿形作比较,以检验磨削是否干涉及砂轮半径和安装角的选取是否正确.基于 Visual C++ 6.0 编制内斜齿轮砂轮修形及误差分析软件,通过仿真正确选择砂轮安装角、砂轮半径,并输出数控砂轮修整程序.最后通过磨削和检测实例,验证了理论的正确性和软件的可行性.

Abstract: In view of grinding interference produced in the process of inner helical gear form grinding,the grinding wheel dressing method for the inner helical gear form grinding was studied.On the basis of establishing the mathematical model of inner helical gear form grinding,the conditional equations sets conforming to the contact points between grinding wheel and tooth space were obtained by means of circle cutting,and then the wheel profile was found through solving the equations by using Newton iteration.The practical profile of wheel simulated by numerical method was compared with the theoretical involute tooth to inspect whether the gear grinding causes interference,and whether the radius of grinding wheel and its installation angle are correct.Wheel dressing and simulating analysis software was prepared based on Visual C++ 6.0 ,which can be used to select the grinding wheel radius and installation angle,and output the computer numerical control (CNC) program for dressing form grinding wheel.The practical inner helical gear grinding test and inspection results show that the dressing method is correct and the dressing software is feasible.
