针对螺旋锥齿轮齿形误差难以精确修正的问题,在国产3906型齿轮测量中心上,采用坐标测量法获得了螺旋锥齿轮的齿面形状;提出进行齿深控制的锥齿轮测量齿面切齿调整参数非线性最小二乘优化反调方法,并建立了反调优化的数学模型;采用该方法对磨齿后的某弧齿锥齿轮小轮进行反调计算,结果表明该方法能较为精确地获取锥齿轮副的切齿调整参数。
The profile error correction of spiral bevel gears is difficult.To solve this problem,the inspected method of spiral bevel gears tooth surface is studied in 3906 gear measuring center.The grids of tooth surface is measured by measurement software.Taking reference tooth surface as the goal,a method of machine setting reverse using approximation algorithms is proposed,and a mathematical model is build.At last,a reverse example based on grinded spiral gear is given.The result shows that the cutting machine setting of bevel gear tooth surface can be exactly calculated.
