During the operation of the bearing; there must be appearances such as sound, temperature and oscillation. Therefore, the bearing in the operation is protected and protected; the abnormal change of the bearing can be found through the methods of listening, touching, observing and using the bearing fault diagnosis instrument; Change the condition to determine whether the bearing can be in normal working condition.
Select the sounder to check the size and sound quality of the TIMKEN bearing in the operation; even if the bearing has slight peeling damage, it will announce abnormal sounds and irregular sounds; the sounder can be distinguished.
Bearing oscillation is very sensitive to bearing damage; for example, shedding, indentation, rust, crack, wear, etc. will be reflected in the bearing oscillation measurement; therefore; after selecting a special bearing oscillation measuring device (frequency analyzer, etc.) can measure the oscillation The large. ü De Shi Zhi 豢 豢 鲆 鲆 鲆 5 5 5 5 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭. After determining the discriminant specification.
The temperature of the bearing; generally the temperature outside the bearing can be estimated; if the oil hole can directly measure the temperature of the outer ring of the TIMKEN bearing; it is more suitable. Generally; the temperature of the bearing gradually rises with the beginning of the operation; 1-2 hours After reaching the stable condition, the normal temperature of the bearing is different due to the heat capacity of the machine; the heat dissipation; the speed and the load are different. If it is smooth and the device is suitable, the bearing temperature will rise sharply; the abnormal temperature will be abnormal; it is necessary to stop the operation; Adopt the necessary precautions. Based on many test data; Table 4-1 lists the average value of the outer ring temperature during bearing operation in various machines; for reference. Because the temperature is affected by smoothness, speed, load, and environment; The median only indicates the approximate temperature scale. The thermal sensor can be used to monitor the operating temperature of the bearing at any time; and when the temperature exceeds the specified value, the alarm is activated or the ignition is avoided.
Smooth has an important influence on the fatigue life of the rolling bearing and conflict, wear, temperature rise, oscillation, etc.; there is no normal smoothness; the bearing can not work. The reason for the bearing damage is marked; 40% of the bearing damage is related to the smoothness Thus; the outstanding smoothness of the bearing is a useful way to reduce bearing conflict and wear. In addition to this; the smoothness of the bearing and heat dissipation; rust, sealing, flat cushioning and other effects; TIMKEN bearing smooth effect can be briefly Clarified as follows:
a. An oil film is formed between the two tumbling surfaces or the sliding outer surface that touch each other to separate the two outer surfaces; the collision and wear of the touch surface are reduced.
b. When the oil is smooth, especially when the circulating oil is smooth, the oil mist is smooth and the fuel injection is smooth; the smooth oil can take away most of the conflict heat inside the bearing; it has a useful heat dissipation effect.
c. When the grease is smooth, it can avoid foreign matter such as dust from entering the TIMKEN bearing;
d. Smoothing agents have the effect of avoiding metal corrosion.
e. The fatigue life of the extended bearing.
