如何延长轴承的使用寿命

首先，润滑是关键。

First of all, the lubrication is the key.

选择合适的润滑系统和高质量的润滑剂。润滑油膜将因承载而彼此接触的油膜表面分离开来，并提供对腐蚀和磨损的必要防护，因此对所有旋转或往复运动零件，特别是轴承和齿轮而言，如需正常运转，润滑油膜不可或缺。

Choose the appropriate lubrication system and the high quality lubricant. Lubricating oil film will come into contact with each other by bearing oil film surface separation, and provides the necessary for corrosion and wear protection, so for all rotating or reciprocating motion parts, especially in terms of bearing and gear, for normal operation, lubricating oil film is indispensable.

如为飞溅式润滑或循环润滑系统，油膜还能传递热量。工厂经常因润滑不当而出现不必要的停机和设备状态恶化。供油不足会导致磨损增加和温度上升，造成过度磨损和/或轴承早期失效及损坏。润滑过度，尤其是高速运转的设备，将因油搅动而产生过多热量，使润滑油发生化学劣化，也会导致轴承损坏。

Such as splash lubrication or circulating lubrication system, oil film can heat transfer. Plants tend to occur due to improper lubrication unnecessary downtime and equipment condition deteriorated. Oil supply deficiency can lead to increased wear and temperature rise, caused by excessive wear and/or premature failure of the bearing and the damaged. Lubrication excessive, especially in high speed running equipment, because of excessive heat resulting from the oil stirring, chemical degradation in the lubricating oil, will result in bearing damage.

正确润滑，定期养护，可避免因润滑问题引起的轴承损坏。保证合理润滑应做到：遵循设备制造商为每台设备设定的使用指南;应注意何时轴承应加脂;注意设备噪音或异常振动;观察润滑油泄漏;监控设备设备的指示仪表，以便尽早发现问题的迹象，如温度波动和/或异常高温;定期对润滑油取样，并查看是否污染。

Correct lubrication, regular maintenance, and can avoid bearing damage caused by lubrication problem. Ensure reasonable lubrication should be: follow the equipment manufacturer for each device using guide; Should be paid attention to when the bearing should be fatliquoring; Pay attention to the equipment noise or abnormal vibration; Observation lubricating oil leakage; Monitoring equipment equipment indicating instrument, in order to detect signs of problems, such as the abnormal temperature fluctuations and/or high temperature; Sampling of lubricating oil regularly, and see whether pollution.

加润滑脂时，应将其充入轴承滚动部件及壳体(或护圈)之间，以保证足量润滑脂进入，关键滚道表面得到充分润滑;其次，如需提高轴承性能，合理调整非常重要。

Add grease, should be filling the rolling bearing components and shell (or retainer), in order to ensure sufficient grease into, the key of raceway surface get sufficient lubrication; Second, if you want to improve the bearing performance, reasonable adjustment is very important.

装配或安装时，如轴承内部间隙过大或过小，或在某些情况下，预加载荷过高，可能导致早期损坏和轴承寿命缩短。除造成停机及代价昂贵的维修外，轴承装配和安装不当还可能会有更多负面作用，如影响其它零件的运转，缩短其使用寿命等。

Assembly or installation, such as bearing internal clearance is too large or too small, or in some cases, the preloading load is too high, can cause early damage and shorten the life of the bearing. In addition to the cause and costly maintenance downtime, bearing assembly and improper installation may also have more negative effects, such as interfere with the operation of other parts, shorten its service life, etc.

根据设备制造商的使用手册，进行装配、安装和定期维护，是预防问题出现的最佳方式。如果时间很紧，可前推调整装置或去掉垫片，以校正过松的锥形滚动轴承组。另一方面，轴承调整过紧，可能导致过热损坏，不得不更换轴承。装配安装轴承的工序必须准确、可重复，且安装完成后可以验证。此外还必须考虑其它零件参数，以优化系统性能。此外，按照要求来使用设备。

According to equipment manufacturer's manual, assembly, installation and maintenance regularly, the best way is to prevent problems. If the time is very tight, can be pushed forward adjusting device or remove the gaskets, too loose to correction of tapered roller bearing group. Bearing adjustment, on the other hand, too close, can lead to overheating damage, had to replace the bearing. Assembly bearing process must be accurate and repeatable, and can be verified after the installation is complete. In addition must also consider other component parameters, in order to optimize system performance. In addition, according to the request to use the equipment.
