采煤机行走轮轴承短时失效原因分析及改进措施
|
摘要
针对采煤机行走轮轴承短时失效的问题,通过理论计算和统计分析,找出了行走轮轴承使用寿命短的原因为润滑不足。针对行走轮轴承润滑不足的问题,提出了使用双侧带密封轴承的解决方案,经实践检验,该方案可将行走轮轴承使用寿命提高到300 d以上,且降低了劳动强度,提高了生产效率。
Aiming at the problem of short time failure of walking wheel bearing of shearer,through theoretical calculation and statistical analysis,the reason of short service life of walking wheel bearing is insufficient lubrication. Aiming at the problem of insufficient lubrication of walking wheel bearing,puts forward a solution of using double-side sealed bearing. Through practice,this solution can increase the service life of walking wheel bearing to more than 300 days,reduce labor intensity and improve production efficiency.
