1. The small machine can be rotated by hand to confirm whether the rotation is smooth. The inspection items have poor operation due to foreign matter, scratches, and indentations. The installation is poor, the torque generated by the mounting is not stable, and the torque is too large due to too small clearance, installation error, and sealing friction. Wait. If there is no abnormality, the power running can be started. Large machinery cannot be rotated manually, so the power is cut off immediately after the start of the no-load, the machine is idling, and the presence or absence of vibration, noise, and contact of the rotating parts is checked. After confirming that there is no abnormality, the power is turned on. The power running starts from the no-load low speed and slowly increases to the rated operation of the specified conditions. The items to be checked during the test run are whether there is abnormal sound, KOYO bearing temperature change, lubricant leakage or discoloration, etc. If an abnormality is found, stop the operation immediately, check the machine, and remove the bearing check if necessary.
2. Bearing temperature can generally be estimated based on the external temperature of the bearing housing. However, it is more accurate to directly measure the temperature of the KOYO bearing outer ring by using the oil hole. The bearing temperature gradually rises from the start of the operation, and the temperature is usually stable after 1 to 2 hours. If the bearing is poorly installed, the temperature will rise sharply and an abnormally high temperature will occur. The reasons are such as excessive lubricant, too small bearing clearance, poor installation, excessive friction of the sealing device, and the like. In the case of high-speed rotation, the selection of the bearing structure and the lubrication method is also the cause. The rotation of the bearing is checked with a stethoscope, etc., and there are strong metal noise, abnormal sounds, irregular sounds, etc. to explain the abnormality. The reasons are poor lubrication, poor accuracy of the shaft or housing, bearing damage, and foreign matter intrusion.
3, from the reasons of use and internal factors to see the reasons for the effectiveness of the bearing, the use of factors mainly depends on whether our method of use is reasonable, the internal factors are actually the level of our choice when choosing KOYO bearings! !
The use factors mainly refer to whether the installation adjustment, use and maintenance, maintenance and repair, etc. meet the technical requirements. The installation condition is one of the primary factors in the use factor. The bearing is often changed due to improper installation, and the force state between the parts of the whole bearing changes, and the bearing runs in an abnormal state and fails early. According to the technical requirements of bearing installation, use, maintenance and maintenance, monitor and check the load, speed, working temperature, vibration, noise and lubrication conditions of the bearing in operation, find out the cause and immediately adjust the cause, make adjustment Back to normal. In addition, it is important to analyze the quality of the grease and the surrounding medium and atmosphere.
