摘　　要：为研究最优的、低成本圆弧型的汽车圆锥滚子轴承的滚子母线修形方案,本文应用MASTA作为计算分析工具,计算出不同圆弧、不同圆弧-直线的母线修形方案下的轴承中各粒滚子的应力;并借助正交试验法找出纯圆弧修形方案和圆弧-直线修形方案中各个几何参数对于轴承滚子最大应力的影响机制;最后,根据正交试验的结果找出圆弧型滚子母线和圆弧-直线型滚子母线的最优几何参数组合。In order to study the optimal low-budgetarc generatrix of rollers of the tapered roller bearing in automobiles,the stress of each roller of different arc generatrix and arc-line generatrix schemes is calculated in this paper where MASTA is applied as an analysis tool.With the help of orthogonal design test,the paper reveals the relationship between the maximum stress of the bearing rollers and each geometric parameter in the pure arc generatrix schemes and the arc-line generatrix schemes.Finally,according to the results of the orthogonal design tests,the optimal arc generatrix and arc-line generatrix are found out.
