In order to judge whether the disassembled inlaid solid lubricated bearing can be used, it should be checked after the bearing is cleaned. Check the state of raceway surface, rolling surface and mating surface, the wear condition of persistence frame, the increase of INA Bearing Clearance and the damage of irrelevant dimensional accuracy drop, which are abnormal.
For non separable small ball bearings, use one hand to check the support of the inner ring and rotate the outer ring to confirm whether it is fluent.Specific judgment method for maintenance of ina inlaid solid lubricated bearing
Specific judgment method for maintenance of ina inlaid solid lubricated bearing
1) Using bearing working state monitoring instrument
It is a convenient and reliable method to judge the working state of INA Bearing and decide when the bearing should be repaired by using such instruments as Ferrograph or SPM or i-id-1 bearing working state monitoring instrument.Specific judgment method for maintenance of ina inlaid solid lubricated bearing
For example, when HD-1 instrument is used, when the pointer approaches the dangerous area from the warning area, and the pointer does not return after taking measures to improve lubrication, it can be determined that it is the problem of the embedded solid lubricated bearing itself.
At this time, the bearing can be reported for repair before entering the dangerous area. How far away from the dangerous area to start the repair can be adjusted by experience.Specific judgment method for maintenance of ina inlaid solid lubricated bearing
Using such an instrument, we can make full use of the working potential of the bearing, report the bearing for repair in time, and avoid faults. It is and economical.
2) Monitor with simple tools
In the absence of the above instruments, the operator can hold a round bar or wrench and other tools to collide with the machine shell close to the INA Bearing, put his ear on the tool and listen for the sound of the embedded solid lubrication shaft transmitted by the tool. Of course, it can also be modified with a medical stethoscope.Specific judgment method for maintenance of ina inlaid solid lubricated bearing
The normal sound of bearing operation should be uniform, stable and not harsh, while the abnormal sound of bearing operation has various intermittent, impact or harsh sounds. First, get used to the normal ina shaft rotation sound, and then you can grasp and judge the abnormal bearing operation sound.

Then, through the accumulation of practical experience, you can further analyze what kind of abnormal sound corresponds to what kind of bearing abnormal phenomenon. There are many kinds of abnormal sounds of inlaid solid lubricated bearings, which are difficult to speak and mainly rely on experience.Specific judgment method for maintenance of ina inlaid solid lubricated bearing
Bearing maintenance: bearing cleaning: when disassembling the lower bearing for maintenance, first record the appearance of the bearing, confirm the residual amount of smoothing agent, and wash the bearing after sampling the smoothing agent for inspection. Use gasoline and kerosene as cleaning agent.Specific judgment method for maintenance of ina inlaid solid lubricated bearing
The cleaning of the removed bearing is divided into coarse cleaning and fine cleaning. They are placed in the container respectively. First, put the metal mesh bottom so that the INA Bearing does not directly contact the dirt of the container.
During rough cleaning, if the bearing rotates with dirt, it will damage the rolling surface of the embedded solid lubrication bearing, which should be paid attention to. In the coarse cleaning oil, use the brush to remove the smooth grease and adhesion. After it is roughly clean, turn to fine cleaning.Specific judgment method for maintenance of ina inlaid solid lubricated bearing
