摘　　要：为了避免调心滚子轴承的边缘应力集中,降低轴承内部最大应力,根据滚动轴承设计理论和接触力学理论,应用有限元方法对某掘进机主轴轴承系统中的调心滚子轴承的密合度进行优化,详细分析多个不同密合度方案在实际工况载荷作用下的应力分布,通过对比确定了调心滚子轴承的最佳密合度,为该型号掘进机主轴轴承系统的设计与制造提供参考。In order to avoid the stress concentration on the edge of self-aligning roller bearing and reduce the maximum stress inside the bearing,according to the rolling bearing design theory and contact mechanics theory,the osculation of the self-aligning roller bearing in the spindle bearing system of a TBM is optimized by using the finite element method,the stress distribution of several different tightness plans under the actual working conditions and loads is analyzed in detail,and through comparison,the optimal osculation of self-aligning roller bearing is determined,which provides a reference for the design and manufacture of the spindle bearing system of this type of TBM.
