为了充分观察机器的定期检查和更换,并拆下轴承,检查滚道表面状况和是否没有损坏,是否可以重复使用,见第5项:进口轴承的检查.运行中的检查项目包括INA轴承的滚动声、振动、温度和润滑状况.具体如下:在运行中发现异常情况时.

In order to fully observe the regular inspection and replacement of the machine, and remove the bearings, check the raceway su-ce condition and whether there is no damage, whether it can be reused, see item 5: inspection of imported bearings. Inspection items in operation include rolling sound, vibration, temperature and lubrication of INA bearings. Specifically as follows: when abnormal conditions are found in operation.

通过麦克风检查轴承的滚动声音.即使进口轴承有轻微的剥落损伤,也会产生不正常、不规则的声音,可以用麦克风分辨.

Check the rolling sound of the bearing through the microphone. Even if the imported bearing has slight peeling damage, it will produce abnormal and irregular sound, which can be distinguished by microphone.

轴承振动对轴承的剥落、压痕、生锈、裂纹、磨损等损伤非常min感,在轴承振动测量中可以反映出来.因此,可以使用专用的轴承振动测量装置(频率分析仪等)来测量振动,不能从频率中推断出异常情况.根据INA轴承的工作情况或传感器的安装位置,测量值从今天到今天都有变化,因此在确定判断标准之前,有必要对每台机器的测量值进行分析比较.

Bearing vibration is very sensitive to the damage of bearing such as spalling, indentation, rust, crack and wear, which can be reflected in bearing vibration measurement. Therefore, the special bearing vibration measuring device (frequency analyzer, etc.) can be used to measure vibration, and the abnormal situation can not be inferred from the frequency. According to the working condition of INA bearings or the installation position of sensors, the measured values vary from today to today, so it is necessary to analyze and compare the measured values of each machine before determining the judgment criteria.

进口轴承的温度可以从轴承外部的温度获得.如果油孔能直接测量轴承外圈的温度,则更为合适.通常情况下,轴承的温度随着运行开始缓慢上升,1-2小时后达到稳定状态.轴承室温度随机化器的热容量、散热量、转速和负荷不同.如果润滑和安装部件合适,轴承温度将急剧上升,并出现异常高温.这时,我们须停止工作,采取必要的预防措施.根据大量试验数据,本表列出了各种INA轴承外圈的平均温度,供参考.

The temperature of the imported bearing can be obtained from the temperature outside the bearing. If the oil hole can directly measure the temperature of the bearing outer ring, it is more suitable. Usually, the temperature of the bearing rises slowly with the start of operation and reaches a stable state after 1-2 hours. The heat caPACity, heat dissipation, rotational speed and load of bearing chamber temperature randomizer are different. If the lubrication and installation parts are suitable, the bearing temperature will rise sharply and abnormal high temperature will occur. At this time, we must stop working and take necessary precautions. According to a large number of test data, the average temperature of various INA bearing outer rings is listed in this table for reference.

轴承润滑对滚动轴承的疲劳寿命、摩擦、磨损、温升和振动起着重要作用.没有正常润滑,轴承就不能工作.对轴承损坏原因的分析表明,约40个百分比的轴承损坏与润滑bu良有关.因此,良好的轴承润滑是降低轴承摩擦磨损的you效措施.此外,轴承的润滑还具有散热、防锈、密封和减震等功能.轴承的润滑可简单描述如下:

Bearing lubrication plays an important role in the fatigue life, friction, wear, temperature rise and vibration of rolling bearings. Bearings cannot work without normal lubrication. The analysis of the causes of bearing damage shows that about 40% of bearing damage is related to good lubrication bu. Therefore, good bearing lubrication is a youeffect measure to reduce bearing friction and wear. In addition, the lubrication of bearings also has the functions of heat dissipation, rust prevention, sealing and shock absorption. The lubrication of bearings can be simply described as follows:

a.在两个滚动或滑动表面之间形成油膜,分离两个表面,减少接触表面的摩擦和磨损.

A. Forming oil film between two rolling or sliding su-ces, separating the two su-ces, reducing friction and wear on the contact su-ce.

b.使用INA轴承油润滑时,特别是使用循环油润滑、油雾润滑和喷油润滑时,润滑油可以带走轴承的大部摩擦热,起到散热的作用.

B. When using INA bearing oil lubrication, especially when using circulating oil lubrication, oil mist lubrication and oil injection lubrication, the lubricant can take away most of the friction heat of the bearing and play the role of heat dissipation.

c.油脂润滑可防止灰尘等异物进入轴承,起到密封作用.

C. Grease lubrication can prevent foreign matter such as dust from entering the bearing and play a sealing role.
