| 摘 要： | 为了提高滚子轴承的工作寿命和承载能力，普遍采用滚子修形。本文研究了直线滚子、全凸滚子、凸弧－直线滚子和对数滚子的母线方程及修形参数，在相同的工况条件下，分析计算了这四种滚子的接触应力沿接触线的变化情况，得出了对数滚子具有最佳受载状态的结论。并以提高轴承工作寿命为目标，建立了确定最佳修形量的数学模型，分析了修形量对轴承受载特性的影响，得出了滚子合理修形可以显著改善高速滚子轴承受载状态的结论

| Abstract: | In order to raise the load carring capacity and working life of roller bearings,different roller profiles are commonly used.In this paper, the four types of roller profiles and their profile modification parameters are studied .Through comparing the contact stresses in the rollers with different modified profiles,the obtained conclusion says that the logarithmic roller profile is the best one with the smallest stress concentration.The mathematical model for optimum profile parameters has been set up to maximize the working life of roller bearing. |
