如何延长轴承寿命(中文2700字,英文1500字)
摘要:自然界苛刻的工作条件会导致轴承的失效,但是如果遵循一些简单的规则,轴承正常运转的机会是能够被提高的。在轴承的使用过程当中,过分的忽视会导致轴承的过热现象,也可能使轴承不能够再被使用,甚至完全的破坏。但是一个被损坏的轴承,会留下它为什么被损坏的线索。通过一些细致的侦察工作,我们可以采取行动来避免轴承的再次失效。
关键词:轴承 失效 寿命
导致轴承失效的原因很多,但常见的是不正确的使用、污染、润滑剂使用不当、装卸或搬运时的损伤及安装误差等。诊断失效的原因并不困难,因为根据轴承上留下的痕迹可以确定轴承失效的原因。
然而,当事后的调查分析提供出宝贵的信息时,最好首先通过正确地选定轴承来完全避免失效的发生。为了做到这一点,再考察一下制造厂商的尺寸定位指南和所选轴承的使用特点是非常重要的。

EXTENDING BEARING LIFE
Abstract:Nature works hard to destroy bearings, but their chances of survival can be improved by following a few simple guidelines. Extreme neglect in a bearing leads to overheating and possibly seizure or, at worst, an explosion. But even a failed bearing leaves clues as to what went wrong. After a little detective work, action can be taken to avoid a repeat performance.
Keywords: bearings  failures  life
Bearings fail for a number of reasons,but the most common are misapplication,contamination,improper lubricant,shipping or handling damage,and misalignment. The problem is often not difficult to diagnose because a failed bearing usually leaves telltale signs about what went wrong.
However,while a postmortem yields good information,it is better to avoid the process altogether by specifying the bearing correctly in The first place.To do this,it is useful to review the manufacturers sizing guidelines and operating characteristics for the selected bearing.
Equally critical is a study of requirements for noise, torque, and runout, as well as possible exposure to contaminants, hostile liquids, and temperature extremes. This can provide further clues as to whether a bearing is right for a job.
