摘要
以N1015型圆柱滚子轴承为研究对象,采用ANSYS探讨凸度偏移对滚子与滚道之间接触应力的影响问题,以合理确定对数母线滚子的凸度偏移量。研究结果表明:在给定的载荷下,凸度偏移量应控制在合适的范围内,否则,滚子与滚道之间的接触应力明显增大,而且接触应力分布会呈现出复杂的非对称性与非均匀性。
Taking a cylindrical roller bearing N1015 as a research object,the contact stress between the roller and the raceway was studied by means of ANSYS in order to determine reasonably the convexity excursion of the logarithmic curve generatrix.The results show that under the given load the convexity excursion should be controlled in an appropriate range.Otherwise,the contact stresses between the roller and the raceway increase observably and the distribution of the contact stresses presents a complex asymmetry and nonuniformity.
