淮安INA轴承在使用过程中具有很强的规律*和重复*。普通优制轴承在使用初期振动、噪声小，但频谱分散，振幅小，可能是由于制造过程中的表面粗糙度等缺馅造成的。
Huaian INA bearings h**e strong regularity and repeatability in use. The vibration and noise of ordinary high-quality bearings are small in the initial stage of use, but the frequency spectrum is dispersed and the amplitude is small, which may be due to the lack of filling such as surface roughness in the manufacturing process.
经过一段时间的轴承运动，振动和噪声都保持在一定的水平，频谱很单一，只有频率的一到两倍。频率超过三个频率的情况很少发生。轴承状况非常稳定，进入稳定工作期。
After a period of bearing movement, vibration and noise are kept at a certain level, the spectrum is very single, only one or two times the frequency. Frequencies **ceeding three frequencies rarely occur. Bearing condition is very stable, entering a stable working period.
连续运行后，轴承的振动和噪声开始增大，有时会出现异常噪声，但振动的增大变化缓慢。此时，淮安INA轴承的峰值开始突然达到一定值。我们认为，此时轴承具有初始失效的特点。
After continuous operation, the vibration and noise of bearings begin to increase, sometimes abnormal noise will appear, but the increase of vibration changes slowly. At this time, the peak value of Huaian INA bearing begins to suddenly reach a certain value. We believe that the bearing has the characteristics of initial failure at this time.
此时，bi须密切监测高温轴承。此后，轴承的峰值开始迅速下降，接近正常值，振动和噪声开始显著增加，并开始加速增加。当振动超过振动标准时，轴承的峰值开始迅速增大。当振动标准和峰度值超过正常值（可用峰度的相对标准）时，我们认为轴承已进入故障生产的后期。设备应及时修理，轴承应更换。
At this time, Bi must closely monitor high temperature bearings. Thereafter, the peak value of the bearing began to decrease rapidly, approaching the normal value, vibration and noise began to increase significantly, and began to accelerate the increase. When the vibration **ceeds the vibration standard, the peak value of the bearing begins to increase rapidly. When the vibration standard and kurtosis value **ceed the normal value (the relative standard of **ailable kurtosis), we think that the bearing has entered the later stage of failure production. Equipment should be repaired in time and bearings should be replaced.
轴承具有后期失效的特点。严重故障（通常是轴承损坏，如轴支架、sao伤、砂支架剥落、滚道、球磨损等）需要不到一周的时间。设备容量越大，速度越快，间隔时间越短。因此，在实际淮安INA轴承故障诊断中，一旦发现晚期故障特征，应果断判断轴承故障，并尽快安排维修。
Bearing has the characteristics of late failure. Serious faults (usually bearing damage, such as axle bracket, Sao damage, sand bracket peeling, raceway, ball wear, etc.) take less than a week. The larger the capacity of the equipment, the faster the speed and the shorter the interval time. Therefore, in the actual Huaian INA bearing fault diagnosis, once the late fault characteristics are found, bearing fault should be judged decisively, and maintenance should be arranged as soon as possible.
轴承使用的主要因素是安装调整、运行维护是否符合技术要求。根据轴承安装、使用和维护的技术要求，对运行中轴承的负荷、转速、工作温度、振动、噪声和润滑情况进行监测和检查。立即发现异常原因，调整后恢复正常操作。
The main factors of bearing usage are installation adjustment, operation and maintenance whether it meets the technical requirements. According to the technical requirements of bearing installation, use and maintenance, the load, speed, working temperature, vibration, noise and lubrication of bearings in operation are monitored and inspected. The abnormal cause was found immediately and normal operation was resumed after adjustment.
由于轴承磨削工艺的改进，采用机床或定程磨削方法对两个套圈的滚道尺寸进行了广泛的测量，使其匹配尺寸控制在规定的工艺尺寸偏差范围内，外圈可与内环和外环组合使用。特尔环电话铃响了。辊套。别无选择。如果工艺的到保证，一般不需要在装配过程中对套管侧的尺寸进行分类，重新测试淮安INA轴承装配的高T值。
Because of the improvement of bearing grinding technology, the raceway dimensions of two rings are measured **tensively by machine tool or fixed-range grinding method, so that the matching dimensions are controlled within the prescribed deviation range of technological dimensions, and the outer rings can be combined with the inner rings and the outer rings. The Tel Ring telephone rang. Roller sleeve. There is no alternative. If the process is guaranteed, it is generally not necessary to classify the dimensions of casing side in the assembly process and re-test the high T value of Huaian INA bearing assembly.
如果在装配过程中滚子与内滚道之间的尺寸偏差分散，则可以对内滚道的尺寸偏差进行分组，以提高匹配率。内滚道A的负偏差和正偏差可以匹配，滚子的正偏差和负偏差可以匹配，使内构件的装配满足技术要求。
If the dimension deviation between the roller and the inner raceway is dispersed in the assembly process, the dimension deviation of the inner raceway can be grouped to improve the matching rate. The negative deviation and positive deviation of inner raceway A can be matched, and the positive deviation and negative deviation of roller can be matched, so that the assembly of inner components can meet the technical requirements.
