机电设备维修是矿山生产的重要组成部分，特别是在机械设备的维修过程中，经常遇到江苏NSK轴承的维护和安装。轴承的维护将直接影响机械设备的运行周期，因此对轴承进行安装和检查是非常重要的。

Mechanical and electrical equipment maintenance is an important part of mine production, especially in the maintenance process of machinery and equipment, often encountered in Jiangsu NSK bearing maintenance and installation. The maintenance of bearings will directly affect the operation cycle of mechanical equipment, so it is very important to install and inspect bearings.

1。术前检查

1. Preoperative examination

小型机械可手动旋转以确认其是否平稳旋转。主要检查项目为：因***、瘢痕和压痕而***不成功。安装不当，安装基座加工不良，旋转力矩不均，间隙小，E、力矩过大。RROR

***all machinery can be manually rotated to confirm whether it is rotating ***oothly. The main examination items were: surgery was not successful because of foreign body, scar and indentation. Improper installation, poor processing of installation base, uneven rotation torque, ***all clearance, E and excessive torque. RROR

大型机械在江苏NSK轴承空载启动后可立即停止运行。它将进行惯性操作，检查是否有振动、声音、旋转部件等。

Large machinery can be stopped immediately after the NSK bearing of Jiangsu bearing is launched. It will carry out inertial operation to check whether there are vibration, sound, rotating parts, etc.

动态旋转从空载开始，江苏NSK轴承缓慢增加到额定操作。检查项目包括异常声音、轴承温度的温度变化、润滑油的泄漏和劣化。当操作异常时，应立即停止操作并在必要时进行检查。

Starting from no-load dynamic rotation, Jiangsu NSK bearings slowly increase to rated operation. The inspection items include abnormal sound, temperature change of bearing temperature, leakage and deterioration of lubricating oil. When the operation is abnormal, the operation should be stopped immediately and checked if necessary.

轴承温度一般是从壳体的外观知道的。江苏NSK轴承温度从操作开始逐渐升高，通常为1～2小时。如果轴承或安装不良，轴承温度将急剧上升，并且会出现异常温升。其原因是润滑油过多、轴承间隙过小、轴承滚珠磨损、安装不当等。在高速旋转条件下，轴承结构的选择不当和润滑方法也是其温升过高的原因之一。

Bearing temperature is generally known from the appearance of the shell. Jiangsu NSK bearing temperature gradually increased from operation, usually 1~2 hours. If the bearing or installation is bad, the bearing temperature will rise sharply, and there will be abnormal temperature rise. The reason is too much lubricating oil, too ***all bearing clearance, wear and tear of bearing ball, improper installation and so on. Under the condition of high-speed rotation, the improper selection of bearing structure and lubrication method are also one of the reas*** for its excessive temperature rise.

2。江苏NSK轴承操作中应注意的问题

2. Problems to be paid attention to in the operation of NSK bearing in Jiangsu

检查设备的运行状态并制定维修计划也是很重要的。状态监测是预防性维修的重要组成部分。江苏NSK轴承故障应定期检查，以避免经常检查轴承，特别是在不重要的设备或恶劣的环境。其中，“听”、“动”、“观察”是三个重要途径。

It is also important to check the operation status of the equipment and make the maintenance plan. Condition monitoring is an important part of preventive maintenance. Jiangsu NSK bearing fault should be checked regularly to ***oid frequent checking of bearings, especially in unimportant equipment or harsh environment. Among them, "listening", "moving" and "observing" are three important ways.

倾听

Listen for

这是为了确定轴承是否异常。如果江苏NSK轴承处于良好状态，它会发出低沉的哀鸣，并且轴承如果发出尖锐的嘶嘶声、吱吱声和其他不规则的声音，通常会指示一个坏的运行状态。

This is to determine whether the bearing is abnormal. If the Jiangsu NSK bearing is in good condition, it will make a deep whine, and the bearings usually indicate a bad running state if they make a sharp hiss, squeak and other irregular sound.

触摸

touch

也就是说，用手触摸装置的外壳，在正常情况下，允许一点温度，但温度太高，这表明轴承的运行状况是有问题的。

That is to say, with the hand touch the shell of the device, under normal circumstances, allow a little temperature, but the temperature is too high, which indicates that the running condition of the bearing is problematic.

观察

observation

检查轴承附近的油封，以免渗入高温或腐蚀性液体或气体沿轴。检查江苏NSK轴承自动润滑系统，确保油或油正确进入轴承，确保正确的充电量。同时检查润滑剂是否变色或发黑。在这种情况下，通常表明润滑剂变质或含有杂质，应立即更换。

Check the oil seal near the bearing to ***oid infiltration of high temperature or corrosive liquids or gases along the shaft. Check the Jiangsu NSK bearing automatic lubrication system to ensure that oil or oil enters the bearing correctly and ensure the correct charging amount. At the same time, check whether the lubricant is discoloring or blackening. In this case, it is usually indicated that lubricants deteriorate or contain impurities and should be replaced immediately.

如果上述三种方法异常，应根据不同情况注意设备检查。

If the above three methods are abnormal, attention should be paid to equipment inspection according to different situati***.
