压榨机滚动轴承失效原因分析及其改进措施

以生产实践中所发生的压榨机锥孔球面滚子轴承损坏事故为例，通过对轴承疲劳寿命的验算，确定轴承损坏属正常原因，分析了腐蚀，轴向力过载，间隙过大，安装不正确等是轴承损坏的原因，提出了改进措施，延长了轴承的作用期限。

Analyse on the Damage of Mill Roller Bearing and Its Prevention

Taking the damage of mill spherical tapered bore roller bearing as apract ical example during production. by checking the bearing's fat igue life, we conf irmthat the damage of bearing is an abnormal cause; and by analysing, we get that the mainreasons of bearing damage are erosion, overload of axial thrust, over clearance andfaulty mounting, Some methods to prevent the bearing damage and prolong the bearing'slif e are proposed,
