Bearing repair and identification of defects

   In order to make the bearing full and long-term to maintain its proper function, it is necessary to do a good job of regular protection and maintenance (regular view).
After the appropriate time to view, so that early detection of problems, to avoid accidents in the future, the progress of productivity and economy is very important.
1, clean
The bearing removed to view, first with the shooting and other methods to do sliding bearing a good appearance records. In addition, to recognize the amount of lubricant remaining and sample the lubricant, and then clean the bearings.
A, the bearing cleaning is divided into rough washed aluminum-based steel ball retaining ring and fine washing, and in the use of the container bronze sets the bottom of the metal grid.
B, rough wash, in the oil with a brush, such as the eradication of grease or sticky material. At the moment if the oil rolling bearings, attention will be due to foreign objects such as tumbling surface damage.
C, fine washing, in the oil slowly rolling bearings, to be carefully carried out.
The general use of the detergent is neutral without water diesel or oil, according to the demand sometimes use the temperature of lye and so on. No matter what kind of cleaning agent, should always filter to keep clean.
After cleaning, immediately on the bearing coated with anti-rust oil or anti-rust grease.
2, view and identify
In order to determine whether the removed bearing can be used from scratch, it is necessary to focus on the scale accuracy, rotation accuracy, internal clearance and cooperation surface, raceway surface, cage and seal.
For the inspection results, can be used by bearings or know the bearing to determine.
The criteria for discrimination are different depending on the mechanical function and the main degree and the viewing period. If the following damage, the bearing shall not be used from scratch, it is necessary to replace.
1) bearing parts of the cracking and shortcomings.
2) Rolling surface of the rolling surface of the stripping.
   3, bearing the fault identification method
Without breaking the view, you can identify or guess the bearing in the operation is faulty, to improve productivity and economy is very important.
The main identification is as follows:
1) through the sound to identify
After the sound to identify the needs of a wealth of experience. It is necessary to go through plenty of training to reach the bearing sound and non-bearing sound. To this end, should be done by hand to carry out this operation. Use a listener or a listening stick on the case to clearly hear the sound of the bearing.
2) through the operating temperature to identify
This method is a relatively recognizable method, limited to the use of jobs in the situation is not changed. For this reason, it is necessary to carry out a series of temperature records. When there is a problem, not only the temperature increases, but also irregular changes.
3) Identified by the condition of the lubricant
       Bearing on the lubricant sampling analysis, after its degree of contamination is mixed with foreign matter or metal powder to determine. This method is particularly useful for bearings or large bearings that can not be accessed.
