Angular contact ball bearing of regular inspection and maintenance
To make the angular contact ball bearings and keep its long-term performance into full play,
Preventive maintenance (, must earnestly
1, cleaning: angular contact ball bearing,
Remove the patrol, use methods such as photography first appearance record.
In addition, to confirm the rest of the lubrication (
Effect: can reduce or avoid friction and wear)
The quantity and the lubricant sampling, and then clean the angular contact ball bearings.
A, angular contact ball bearing,
Cleaning divided into rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame.
Bearing bearing lubrication method, divided into grease lubrication and oil lubrication.
In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method.
If only consider lubrication and oil lubrication.
However, grease lubrication can simplify the structure of bearing the surrounding of the special features, compare the pros and cons of grease lubrication and oil lubrication.
B, rough washing, oil using a brush to remove (
Grease or adhesive.
At this point if the rotation Angle contact ball bearing in the oil, pay attention to the rolling surface due to foreign bodies such as damage.
C, fine cleaning, in oil slowly rotating angular contact ball bearing,
Must be carefully.
Usually use (
The detergent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc.
No matter use which kinds of detergent, often should filter clean.
After cleaning, immediately on the angular contact ball bearing coating anticorrosive oil or antirust grease.
2, inspect and judging: in order to judge removed angular contact ball bearing,
Whether to use, to inspect its dimensional accuracy (emphatically
Precision and internal clearance and mating surface, raceway surface, cage and seal rings etc.
About the test results that can be used by angular contact ball bearing,
The judgement or master of angular contact ball bearings.
Judgment standard according to the mechanical properties and the importance and patrol cycle, etc.
Bearing the use of clean environment for bearing is very important.
Such as cross section thin-walled bearing ring rotation surface and rough surface precision of the rolling element is about 1/10 microns, this smooth surface of the ball if polluted, its influence is very serious.
If you have the following injury, angular contact ball bearings (
Shall not be used again,
That must be replaced.
Angular contact ball bearings (a.
Parts of fracture (
B raceway surface material on the surface of the rolling strip.
