已运行一段时间的进口轴承可用于通过三条直线检测轴承质量。
The imported bearings that have been running for a period of time can be used to detect the bearing mass through three straight lines.
（1）试验方法。滚动轴承用肉眼检查。内滚道和外滚道不应有剥落痕迹和大磨损，并有圆形槽；所有滚动台不应有斑点、裂纹和剥落场景；维护框架不应松懈，不损坏，不磨损，滚动体之间的间隙为A。太大了。
(1) test method. The rolling bearings are checked by the naked eye. The inner raceway and the outer raceway should not have flaking marks and large wear, and have circular grooves; all the rolling tables should not have spots, cracks and flaking scenes; the maintenance frame should not be lax, not damaged, not worn, and the clearance between the rolling bodies is A. It's too big。
（2）手的感觉。普通轴承与滚动元件的内外环之间的间隙为0.005～0.010毫米。对于一个阶段使用的滚动轴承，如果内圈用手指捏住，就不应该有明显的噪声。
(2) the feeling of the hand. The gap between the inner ring and the outer ring of the common bearing and the rolling element is 0.005 to 0.010 millimeters. For rolling bearings used in one stage, if the inner ring is pinched with fingers, there should be no obvious noise.
（3）旋转法。一只手握住轴承的内座圈，另一只手转动外座圈。轴承应该是灵巧的，不应该感觉到径向摆动。
(3) the rotation method. One hand holds the inner race of the bearing and the other hand turns the outer race. Bearings should be dexterous and should not feel radial swings.
在试验中，应结合上述3种经验，准确判断滚动轴承的操作技巧。对于圆锥滚子轴承，还应检查滚动元件是否位于外环两端。如果它向前移动，它不应该超过1.5毫米。
In the test, the above 3 experiences should be combined to accurately judge the operation skills of rolling bearings. For tapered roller bearings, check whether the rolling elements are located at both ends of the outer ring. If it moves forward, it should not exceed 1.5 millimeters.
江苏INA轴承噪声不规则、不规则。我们需要不同的措施来避免损坏轴承。
Jiangsu INA bearing noise is irregular and irregular. We need different measures to avoid damaging the bearings.
江苏INA轴承的常规噪声主要由三个原因引起：表面变形和滚道表面剥落或异物引起滚动表面产生压痕、锈蚀或疤痕。
The conventional noise of Jiangsu INA bearings is mainly caused by three reasons: surface deformation and raceway surface exfoliation or foreign objects cause indentation, rust or scars on the rolling surface.
如果江苏INA轴承表面变形和滚道表面剥落，应更换江苏INA轴承。
If Jiangsu INA bearing surface deformation and raceway surface spalling, Jiangsu INA bearing should be replaced.
如果异物产生滚动表面上的压痕、锈蚀或疤痕，则可以清洗部件，改进密封装置，使用清洁润滑剂，如果不再使用，轴承将被更换。
If the foreign body produces the indentation, rust or scar on the rolling surface, the parts can be cleaned, the sealing device is improved, the clean lubricant is used, and the bearings will be replaced if they are no longer used.
江苏INA轴承的不规则噪声
Irregular noise of INA bearing in Jiangsu
江苏INA轴承发出的不规则噪声有两个原因：江苏INA轴承有外来杂质侵入，江苏INA轴承间隙过大。
There are two reasons for irregular noise emitted by INA bearings in Jiangsu: the INA bearing of Jiangsu has foreign invasion, and Jiangsu INA bearing clearance is too large.
江苏INA轴承在侵入异物时会产生不规则的噪声，因此轴承和轴承部件应进行清洗。
Jiangsu INA bearing will produce irregular noise when it invades foreign objects, so bearing and bearing parts should be cleaned.
江苏INA轴承过大的间隙也会引起不规则的噪声。有必要研究匹配和轴承间隙来改变预紧力。
The excessive clearance of INA bearings in Jiangsu can also cause irregular noise. It is necessary to study matching and bearing clearance to change the preload.
