| 摘 要： | 针对轴承在压装过程中压装力计算问题，运用有限元软件分析了不同过盈量、不同轴承和壳体间摩擦因数对压
装力的影响；分析了当轴承、壳体间存在装配偏差以及壳体存在形状误差时对压装力的影响。研究表明，随着过盈量的
增大时，压装力也将增大；摩擦因数对压装力影响比较大，并且呈现较好的线性关系；当轴承存在位姿偏差或壳体孔倾斜
时，压装力都将增大；当轴承外圈存在鼓形、锥形、倒锥形误差时，压装力将增大，当存在凹形形状误差时，压装力将减小。

| Abstract: | Regarding to the problem of press-fit forces calculation in the bearing press-fit process, finite element software
was applied to analyze the influence of different interference. different coefficients of friction between bearing and
housing on the press-fit force. The influence of assembly deviation between bearing and housing, and shape deviation of
housing on the press-fit force was also analyzed. The study shows that when the interference increases. the press-fit force
will increase; the coefficient of friction has great influence on press-fit force and presents a good linear relationship;
when assembly deviation exits, the press-fit force will increase; when shape deviation of drum.cone and inverted-cone
exits on the bearing outer ring, the press-fit force will increase. However. when shape deviation of concave exits. the
press-fit force will decrease. |
