Core Tips: The operator and equipment maintenance engineer of the machine must maintain a high degree of bearing the fault signal of the bearing, such as the sound, temperature rise and vibration of the bearings. The operator and equipment maintenance engineer of the machine of the bearing of the middle bearing must maintain a highly vigilant "fault signal" of the bearing, such as the sound, temperature rise and vibration of the bearing. The method of detecting the middle bearing is: observation, listening, and touch.

Observation: The bearing box should be opened regularly to check the shaft to the oil seal with visual inspection, and check the condition of the oil seal near the bearing to ensure that they are sufficient to prevent the thermal liquid or corrosive liquid and the gas penetrate into the bearings along the axis heart.

Listening: It is a very common way to use listening to discern irregular operations. If the bearing is in a good operating condition, it will make a low voice. If a sharp hissing, squeak, and other irregular sounds make a bad operating condition in the bearing. The sharp squeaking sound may be caused by inappropriate lubrication; inappropriate bearing gaps can also cause metal sounds; the deresses on the bearing outer ring can cause vibration and cause smooth and crisp sound; if it is caused by installation, it is caused by installation. The knock scars will also produce noise, which will vary with the height of the bearing rotation; if there is intermittent noise, it means that the scroll part may be damaged; Bearing damage will produce irregular and huge sounds.

Touch: High temperature often indicates that the bearings are in abnormal work, and high temperatures are also harmful to the bearing lubricant. If the bearing is more than 120 ° C temperature, the long -term operation will greatly reduce the bearings life. The reasons for the increased temperature of the bearing are: insufficient lubrication or excessive lubrication, impurities in the lubricant, excessive load, bearing damage, insufficient gap, and high friction from oil sealing, and so on. Therefore, continuous monitoring bearing temperature is necessary.
