摘要 为开展弧齿锥齿轮齿面接触分析,需确定一个初始点作为接触迹线、传动误差等参数的计算起始点。通过建立轮齿展成坐标系及齿面方程,对大小齿轮齿面作离散化处理,基于齿面两点间距离最小原则,针对含安装误差的弧齿锥齿轮初始点确定的问题,提出一种新的计算接触分析初始点的方法。研究结果表明,对于不同的安装误差,该方法均能快速确定初始点的位置,并得到相应的接触迹线及传动误差曲线。 To carry out the tooth contact analysis(TCA)of spiral bevel gears,it is necessary to determine an initial point as the starting point for calculating contact path and transmission error.Based on minimum distance principle between two chosen points on tooth surfaces,an approach to determination of the initial point for TCA of spiral bevel gears with installation errors is proposed,and the coordinate system and tooth surface equation are established for discretizing the tooth surface of both gears.The results show that for different installation errors,the position of the initial point could all be determined,and the corresponding contact path and transmission error curve could be obtained.
