轴承使用寿命的因素

日期:2019-05-16 23:58 作者:ina 阅读:
影响SUNTHAI轴承使用寿命的因素可能有很多,可以从使用因素和内在因素来进一步的说明。nsk轴承代理商依按摩擦性质而定,直线运动导轨可以分为滑动摩擦导轨、滚动摩擦导轨、弹性摩擦导轨、流体摩擦导轨等种类。
  使用因素主要是指安装调整、使用保养、维护修理等是否符合技术要求。根据SUNTHAI轴承安装、使用、维护、保养的技术要求,对运转中的圆锥滚子轴承所承受的载荷、转速、工作温度、振动、噪声和润滑条件进行监控和检查,发现异常立即查找原因,进行调整,使其恢复正常。安装条件是使用因素中的首要因素之一,轴承往往因安装不合适而导致整套轴承各零件之间的受力状态发生变化,轴承在不正常的状态下运转并提早结束使用寿命。
     为使SUNTHAI轴承充分发挥并长期保持其应有的性能,必须切实做好定期维护保养(定期检查) 。通过适当的定期检查,做到早期发现故障,防止事故于未然,对提高生产率和经济性十分重要。
1、清洗
     将SUNTHAI轴承拆下检查时,先用摄影等方法做好外观记录。另外,要确认剩余润滑剂的量并对润滑剂采样,然后再清洗圆锥滚子轴承。
    
  A、轴承的清洗分粗洗和精洗进行,并可在使用的容器底部放上金属网架。
    
  B、粗洗时,在油中用刷子等清除润滑脂或粘着物。此时若在油中转动SUNTHAI轴承,注意会因异物等损伤滚动面。
    
  C、精洗时,在油中慢慢转动SUNTHAI轴承,须仔细地进行。
     通常使用的清洗剂为中性不含水柴油或煤油,根据需要有时也使用温性碱液等。不论用哪种清洗剂,都要经常过滤保持清洁。清洗后,立即在圆锥滚子轴承上涂布防锈油或防锈脂。
2、检查与判断
     为了判断拆下的SUNTHAI轴承能否重新使用,要着重检查其尺寸精度、旋转精度、内部游隙以及配合面、滚道面、保持架和密封圈等。关于检查结果,可由用惯轴承或精通圆锥滚子轴承者进行判断。判断的标准根据机械性能和重要度以及检查周期等而有所不同。如有以下损伤,SUNTHAI轴承不得重新使用,必须更换。
    
  A、轴承零部件的断裂和缺陷。日本nsk轴承轴承工业飞速发展,轴承品种由少到多,产品质量和技术水平从低到高,行业规模从小到大,已经形成了产品门类基本齐全、生产布局较为合理的专业生产体系。
    
  B、滚道面物滚动面的剥离。
  轴承的制造一般要经过锻造、热处理、车削、磨削和装配等多道加工工序。各加工工艺的合理性、先进性、稳定性也会影响到轴承的寿命。其中影响成品圆锥滚子轴承质量的热处理和磨削加工工序,往往与轴承的失效有着更直接的关系。近年来对轴承工作表面变质层的研究表明,磨削工艺与轴承表面质量的关系密切。
