摘要
圆锥轴承滚子-滚道凸度设计包括轮廓设计和凸度量设计。在通用的对数凸型轮廓基础上,凸度量在滚子和滚道上的分配是一个有待研究的课题。通过计算特定工况下滚子-滚道的接触应力水平,来衡量设计的合理性。以NP569484-NP644537圆锥滚子轴承为例,用正交法分组,将取样轴承的内、外圈以及滚子的凸度分为若干匹配等级,并从中选取数种特征匹配;对各种匹配关系进行有限元分析,在保证有充分的接触长度的同时,接触应力应满足工程条件。
The crowning design of tapered roller bearing includes the profile design and the convex metric design. Based on the general logarithmically convex type, the distribution of convex metric on the roller-raceway is a subject to be studied in the future. Through the calculation of particular condition for the level of roller-raceway contact stress, the design rationality is evaluated. The tapered roller bearings NP569484-NP644537 as an example, using the orthogonal groups method, matching several level classification for the roller-raceway of sampling bearing to select feature matching, the finite element analysis is done for feature matching. The contact stress should meet the engineering conditions meanwhile ensure the sufficient contact length is ensured.
