Rigorous protocols must be followed when mounting ball bearings to avoid structural damage and subsequent malfunctioning or unexpected failures. Unconventional mounting procedures may produce excessive contact pressures between the elements of the bearing, therefore the whole process must be well-understood and modelled to prevent unwanted effects. Specifically for angular ball bearings, fitting axial forces should always be applied over the raceway subjected to the shrink-fit to avoid contact forces arising on the ball. In the present study, such an axial force is applied unconventionally, such that the axial force is transferred to the shrink-fit raceway through the balls. In this scenario, the evaluation of the contact areas and the pressure distributions is accomplished by exploiting both analytical and FEM approaches, supported by bespoke experimental tests to determine the relevant frictional coefficients and mounting forces. The study demonstrated how analytical methods can successfully replace more demanding FEM-based tools for the evaluation of the bearing mounting force and contact pressure and extent. FEM modelling can, however, be more accurate when dealing with more generic boundary conditions and more intricate geometrical features involved.

安装滚珠轴承时必须遵循严格的协议，以避免结构损坏和随后的故障或意外故障。非常规的安装程序可能会在轴承元件之间产生过大的接触压力，因此必须充分理解整个过程并对其进行建模，以防止出现不必要的影响。特别是对于角接触球轴承，安装轴向力应始终施加在热压配合的滚道上，以避免球上产生接触力。在本研究中，非常规地施加这种轴向力，使得轴向力通过球传递到热压配合滚道。在这种情况下，接触面积和压力分布的评估是通过利用分析和有限元方法来完成的，由定制实验测试支持，以确定相关的摩擦系数和安装力。该研究展示了分析方法如何成功取代要求更高的基于有限元的工具来评估轴承安装力和接触压力及范围。然而，在处理更通用的边界条件和涉及的更复杂的几何特征时，FEM 建模可以更加准确。
