SKF轴承的探究损伤原因和处理方法

最近,许多用户提出问题,说SKF轴承损伤是怎样造成的。一般情况下,如果正确使用轴承,可以使用至达到疲劳寿命为止。但在平常操作过程中,也会有意外致使其过早的损伤,不能耐于使用的情况。这种早期损伤,与疲劳寿命相对,对被称为故障或事故的品质使用限度。多起因于安装、使用、润滑上的不注意,从外部侵入的异物,对于轴、外壳的热影响之研究不够充分等。关于轴承的损伤状态,比如:滚子轴承的套圈挡边的卡伤,作为原因可考虑,润滑剂不足、不适合、供排油构造的缺陷、异物侵入、轴承安装误差、轴的挠曲过大,也会有这些原因重合因此,仅调查SKF轴承损伤,很难得知损伤的真正原因??墒?,如果知道轴承的使用机械、使用条件、轴承周围的构造、了解事故发生前后的情况。
  为了使SKF轴承尽可能长时间地以良好状态维持轴承本来的性能,要对轴承经常保养、检修和异常之处的处理,确保运转的可靠性,提高生产性、经济性。保养最好相应机械运转条件的作业标准,定期进行。内容包括轴承,监视运转状态、轴承补充或更换润滑剂、定期拆卸的检查。
  首先,来看是怎样造成轴承烧伤呢?
  1、轴承的润滑不良,可能使用了不正规的润滑剂,润滑剂过多或过少都是不正确的;
  2、过大载荷(预压过大);
  3、运行转速过大;
  4、游隙过小;
  5、有水或其他的异物侵入,污染了轴承;
  6、轴、轴承箱的精度不良、轴的挠度大。
  那么当轴承出现烧伤时,又该如何处理呢?
  选用正确的SKF轴承润滑剂,使用量要适合,而且要纠正轴承的选择是否正确。其次研究其配合度、轴承间隙和预压,并且改善密封装置。最后检查轴和轴承箱的精度。要是有专家在旁边指导这是最好不过了,试着学其操作过程。
  SKF轴承的使用寿命与烧伤程度有着直接关系,在轴承日常运转中一定要注意,免得轴承出现问题
