Principle of Operation
Linear bearing is a linear motion system, used for linear stroke and cylindrical shaft. Because the bearing ball is in contact with the bearing jacket point, the steel ball rolls with the minimum friction resistance, so the linear bearing has small friction and is relatively stable. It does not change with the bearing speed, and can obtain the smooth linear motion with high sensitivity and high precision.
If the linear bearing meets the fault, how to solve it?
The fault phenomenon of linear bearings is generally manifested in two kinds, one is that the temperature of the bearing safety part is too high, the other is that there is noise in the bearing operation.
1. The bearing temperature is too high
When the mechanism is running, the installation part of the bearing is allowed to have a certain temperature. When you touch the shell of the mechanism with your hand, it should be normal to not feel hot, otherwise it indicates that the temperature of the bearing is too high. The reasons for the high temperature of the bearing are: the quality of the lubricating oil does not meet the requirements or deterioration, the viscosity of the lubricating oil is too high; The mechanism assembly is too tight (insufficient clearance); Bearing assembly is too tight; The bearing seat ring rotates on the shaft or in the shell; Excessive load; Bearing cage or linear body fracture, etc.
2. Bearing noise
The linear bearing is allowed to have a slight running sound in the work. If the sound is too large or there is abnormal noise or crash, it indicates that the bearing is faulty. The reasons for the noise of linear bearings are more complex. One is the wear of the inner and outer rings of bearings. Due to this wear, the fit relationship between bearings and housing, bearings and shaft is damaged, leading to the axis deviated from the correct position, and abnormal sound is generated when the shaft moves at high speed. When the bearing is tired, the surface metal spalling will also increase the radial clearance of the bearing and produce abnormal sound. In addition, insufficient bearing lubrication, the formation of dry friction, and bearing breakage will produce abnormal sound. After the bearing is worn loose, the cage is loose and damaged, and there will be abnormal sound.
