Do you know what factors make the bearing temperature higher
In the course of use, many people will encounter the situation that the bearing temperature is too high, but there is no way to solve it. If there is no direction bearing temperature is too high, it will cause the bearing to be burned, and the machinery will also be affected. When we use imported bearings or domestic bearings, we must use them carefully, take good care of the bearings in the machine, and do not burn the bearings. Once we find that the temperature of the bearings is too high, we must take corresponding remedial measures. Today, I will explain the relevant content to you, I hope it will be helpful to you. First of all, the bearing temperature is too high, which is an important reason for bearing damage, so what are the main reasons for the high bearing temperature? 1. The quality of the lubricant is not good, and the amount used is insufficient, so that the message part is not directly contacted to produce friction, and the friction between the solid and the liquid is formed. If the quantity of lubricating oil is insufficient or the quality is poor, the message part will be directly rubbed and heated, or the heat cannot be taken away by the lubricating oil, which will increase the bearing temperature; 2. The quality of the rotating bearing assembly is poor, and the gap between the bearing rain jacket is too large or Too small; 3, the quality of the bearing is not good, the rotating bearing surface has cracks, chipping, peeling, etc., which will destroy the stability and uniformity of the oil film, and cause the bearing to heat up; 4, the sealing felt is too tight to cause heat; 5, the bearing Excessive vibration and too much pressure. Bearing noise: Rolling bearings are allowed to have a slight running noise during operation. If the noise is too loud or there is abnormal noise or impact, it indicates that the bearing is faulty. For rolling bearings, the cause of noise is more complicated. One is the wear of the mating surfaces of the inner and outer rings of the bearing. Due to this kind of wear, the matching relationship between the bearing and the housing and the bearing and the shaft is destroyed, causing the axis to deviate from the correct position, and abnormal noise occurs when the shaft is moving at high speed. When the bearing is fatigued, the metal on its surface will peel off, which will also increase the radial clearance of the bearing and produce abnormal noise. In addition, insufficient bearing lubrication, formation of dry friction, and bearing breakage will cause abnormal noise. After the bearing is worn loose, the cage is loose and damaged, and abnormal noise will also be produced.
