摘　　要：首先给出4种不同的圆柱滚子修形母线数学方程。在此基础上,以有限元方法通过对比同一型号圆柱滚子轴承在相同的载荷条件下,4种不同修形母线的滚子对应的压应力沿滚子母线方向的分布,分析了滚子各种修形母线的优劣,为选择滚子修形母线提供依据。First,four different mathematical equation of cylindrical roller correction generatrix was given. On this basis, using ifnite element method, by comparing the press stress distribution along correction genetatrix of the four roller with different correction generatrix for the same cylindrical roller bearing under the same loading condition, the advantages and disadvantages of different correction generatrix for the rollers are analyzed, so as to provide basis for the selection of roller correction generatrix.
