Abstract High loaded oscillating bearings are used on several industrial fields such as robotics, wind power, aeronautics and aerospace. These bearings are subjected to extremely high local contact pressures and relatively low oscillatory speed. In this work, endurance tests on commercial single row spherical roller bearings enable to propose a degradation scenario for the bearing lifecycle. Topographical analyses carried out at each phase of the bearing life allowed to understand the degradation evolution at the interface between the inner-ring raceway and rolling elements. The analysis of the experimental results, with the support of numerical stress analysis, led to the understanding of the involved accommodation mechanisms. Then, a comparison with the wear processes in deep-groove ball bearings is provided.

高载荷振荡下的滚子轴承：寿命演化和适应机制

摘要 高载荷摆动轴承广泛应用于机器人、风电、航空航天等多个工业领域。这些轴承承受极高的局部接触压力和相对较低的振荡速度。在这项工作中，商业单列调心滚子轴承的耐久性测试能够为轴承生命周期提出退化方案。在轴承寿命的每个阶段进行的地形分析允许了解内圈滚道和滚动元件之间界面处的退化演变。对实验结果的分析，在数值应力分析的支持下，导致对所涉及的调节机制的理解。然后，提供了与深沟球轴承磨损过程的比较。
