端面弧齿联轴节加工参数误差对齿面误差的影响

Influence of the Manufacturing Parameter Error on Tooth Surface Error of curvic coupling

为了研究机床加工参数调整误差对端面弧齿联轴节齿面几何精度的影响,推导了含多个加工参数调整误差的端面弧齿通用偏差齿面方程;结合齿面偏差(描述偏差理论齿面对标准齿面的偏离)、节距偏差两个误差指标,构建出轮齿齿面几何误差分析模型。并辅以实例分析轮齿磨削加工时各参数调整误差对其节距偏差及齿面偏差的影响,绘制了关系图定量描述其影响。

To investigate the influence of manufacturing parameter adjustment errors of machine tool on the tooth surface geometrical precision of curvic coupling,the general tooth surface deviation equation which contained multiple processing parameter adjustment errors is inferred,and combined with two error index of tooth surface deviation（describe the deviation of theoretical offset tooth surface from standard one） and pitch deviation,the error analysis model of tooth surface geometry is constructed. With an example,the influence of manufacturing parameter adjustment error on tooth surface deviation and pitch deviation is analyzed,and the relational graph to describe its influence is drawn up.
