Let's start with the oscillation of the imported bearings; the three aspects of tumbling and temperature; because the smooth effect of the bearing is relatively large; therefore, as a separate chapter, we will expand to clarify:
The first is to check the oscillation of the imported bearings in the work from the shedding, indentation, corrosion, cracks, wear, etc. will be reflected in the oscillation measurement of the imported bearings; the impact of the imported bearing oscillation on the bearing is very sensitive; The special imported bearing oscillating measuring device (frequency analyzer, etc.) can be used to measure the large oscillation. U De Shi Zhi è±¢ è±¢ 鲆 鲆 鲆 5 5 5 5 5 å’›è¿©æ¦ å’›è¿©æ¦ ç”±äºŽ 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于 由于The orientation is different; therefore, the demand is analyzed beforehand to determine the specification of each machine.
The second is to check the sound condition of the imported bearing when it rolls over. Because the imported bearing has slight damage such as peeling, it will announce abnormal sounds and irregular sounds; therefore, the sounder can be used for differentiation; the sounder is selected; The size and sound quality of the bearing tumbling sound to view; play early to avoid the effect.
In the end, it is necessary to check the temperature of the imported bearing. If the oil hole can directly measure the bearing outer ring temperature, it is more suitable. Under normal conditions; the temperature of the imported bearing; generally can be estimated according to the temperature of the outdoor bearing inlet. If it is smooth and the device is suitable, the bearing temperature will rise sharply; abnormal temperature will occur; it is necessary to stop the work; take necessary precautions. Generally; the temperature of the imported bearing gradually rises with the beginning of the work; after 1-2 hours Arriving at a stable condition. The normal temperature of the imported bearings is due to the heat capacity of the machine; the heat dissipation; the speed and load are different. If necessary, the operating temperature of the bearing can be monitored at any time by using a thermal sensor; and the alarm is activated when the temperature exceeds the specified value. Stop to avoid the burning of the Shaft incident.
About the temperature encountered in the operation of imported bearings; the sound and oscillation conditions are mentioned here first; expect to have a little help for friends.
