航空轴承7217-C217QT-AKZ-20失效分析报告

本报告对中国生产的型号为 7217-C217QT-AKZ-20 的 HRB 轴承进行失效分析。该轴承的背景资料暂缺，属于实验过程失效的陪衬轴承，轴承送检时已经卡死，钢球无法正常滚动。根据轴承型号，该轴承为角接触球轴承。查询国家标准《GB/T292-2007》，该轴承属于锁口外圈型角接触球轴承，特点是外圈两侧厚度不一致，内圈两侧厚度一致。轴承共有钢球 10 颗，保持架为对半结构，用铆钉连接

This report performs failure analysis on an HRB bearing with model number 7217-C217QT-AKZ-20 manufactured in China. Currently, no relevant background information is available for this bearing. It served as a control bearing and failed during the experiment. When submitted for inspection, the bearing was already seized, with its steel balls unable to roll normally. Based on its model number, this bearing is an angular contact ball bearing. According to the national standard GB/T 292-2007, this belongs to the locked outer ring type angular contact ball bearing, which features uneven thickness on both sides of the outer ring and uniform thickness on both sides of the inner ring. This bearing is equipped with 10 steel balls, and its cage has a split-half structure connected by rivets.
