航空轴承失效模式研究报告

轴承是广泛应用于制造业重要的机械零部件，是配套的精密基础件，同时也是最易损坏的元件之一。机械的许多故障都与轴承有关，轴承工作性能的好坏直接影响到与之相关联的轴以及安装在轴上的齿轮乃至整台机器设备的性能。轴承的损伤和失效通常使机械设备的生产能力降低，产品质量下降，甚至造成人身和设备事故。本文通过相关资料查阅结合失效航空轴承样品的失效分析工作，对航空主轴轴承的失效模式进行整理，明确了接触疲劳、塑性变形、异常磨损等几种常见的航空轴承失效模式的主要失效特征和判断依据，为今后的航空轴承制造工艺及性能优化提供帮助。

Bearings are critical mechanical components widely utilized in the manufacturing industry, acting as precision supporting basic parts and ranking among the most easily damaged elements. A large number of mechanical failures are linked to bearings, and the operational performance of bearings directly influences the performance of the associated shafts, gears installed on these shafts, and even the entire mechanical equipment. Damage and failure of bearings typically reduce the production capacity of mechanical equipment, degrade product quality, and may even lead to personal injuries and equipment accidents. This paper organizes the failure modes of aerospace spindle bearings through literature review combined with failure analysis of failed aerospace bearing samples, clarifies the main failure characteristics and judgment criteria for several common failure modes of aerospace bearings including contact fatigue, plastic deformation and abnormal wear, and provides guidance for the subsequent optimization of aerospace bearing manufacturing processes and their performance.
