如何避免进口轴承使用不当过早损伤
发布日期：2024-02-07
一般使用进口轴承，由于摩擦较小，损伤较小，所以进口轴承的使用寿命均可以达到疲劳寿命。但是如果在使用过程中由于发生意外，也可能造成早期损伤，从而无法使用。一般不是因为疲劳寿命达到而造成无法使用的情况，我们成为早期损伤，或者直接叫使用故障或事故。一般多发生于进口轴承的安装、使用、润滑等情况上。
进口轴承的结构；一般情况下不同的机件结构不同，其加工工艺就不一样，如果在不同的机件上使用不匹配的进口轴承，那么肯定很容易使进口轴承受到损伤。
改善加工工艺； 进口轴承在加工的热处理环节上最好使用下限淬火加热温度，适当的延长保温时间，这样做可以提高轴承的合金浓度，可以增强轴承的冲击韧性。 改进加工监测手段； 促进加工质量的改进。如改进流通道曲率位置的监测，提高汽车轴承装配后的整体性能，改善进口轴承工作状况。
预防措施
1、测量机体主轴承孔同轴度及圆度，同时测量曲轴的跳动量，以此选配轴瓦的厚度，使润滑间隙均匀。也可采用刮研法配制轴瓦。
2、提高轴承的维修和装配质量，严格控制连杆质量。对新、旧连杆一律要求测量其平行度及扭曲度，不合格的连杆禁止装配；轴承座内的上下两片轴瓦的瓦口均应高出轴承座平面30-50mm，以保证轴承不致松动；装配曲轴时防止歪斜及轴承螺栓的扭矩不均以避免曲轴弯曲变形。净化组装现场环境，制作缸套防尘盖，确保柴油机组装的清洁度。 【中国轴承网】将为广大轴承行业者提供最全的轴承型号查询，最及时、前沿的轴承资讯。
