In order to give full play to the bearing and long maintained its proper performance, you must do a good job of regular maintenance (periodic inspection).
By appropriate periodic inspection, so that early detection of failure to prevent accidents in the first place, to improve the productivity and economic importance.
1, cleaning
Remove the bearing inspection, photography and other methods to do first with the appearance of records. In addition, to confirm the remaining amount of lubricant and lubricant samples, and then cleaning bearings.
a, bearing cleaning of rough wash and sperm washing and can be placed in the bottom of the container used metal grid.
b, coarse wash, brush, etc. used in the oil or grease removal adhesive material. At this point if rotating bearings in oil, attention and other damage due to foreign objects rolling surface.
c, sperm washing, in the oil slowly rotating bearings should be carried out carefully.
Commonly used cleaning agents for the neutral water diesel or kerosene, is sometimes necessary to use warm lye. Regardless of what kind of cleaning agent filter should always be kept clean.
Cleaned immediately after anti-rust coating on the bearing grease oil or rust.
2, check with the judge
In order to determine whether the re-use of the removed bearing should focus on checking the accuracy of its size, rotation accuracy, internal clearance and with the surface, raceway, cage and ring.
On the inspection results, may be used to bearing or bearings were judged proficient.
Determine the mechanical properties and the criteria according to the degree of importance and checking cycles vary. If the following injury, the bearings must not be reused and must be replaced.
1) bearing parts breakage and defects.
2) rolling surface raceway material peeling.
3, the bearing fault identification method
Not by removing checks to identify or predict the bearing in operation without failure, to improve productivity and economy are very important.
The main identification methods are as follows:
1) identified by voice
Identify needs through sound experience. Must be adequately trained to recognize bearing achieve sound and non-bearing sound. To do this, you should try to carry out this work by hand. A listening or listening rods attached to the housing can clearly hear the sound of the bearing.
2) identification of the operating temperature
This method is relatively identification method is limited to use in the operation state is not changing situations. Therefore, the temperature must be continuously recorded. Fails, only the temperature rises, there will be irregular changes.
3) to identify the state of the lubricant
The lubricant sampling and analysis, through its pollution level is mixed with foreign matter or metal powders to judge. This method does not close observation of the bearing or large bearings are particularly effective.
