In order to make full use of the bearing and long-term maintenance of its proper function, it is necessary to do a good job of timing protection maintenance (regular view).
After proper timing, it is very important to improve the productivity and economy by finding faults early and avoiding accidents.
1, clean
When the bearings are removed, the sliding bearings are first recorded by shooting and so on. In addition, admit the amount of remaining lubricant and sample the lubricant before cleaning the bearings.
The cleaning of the A, the bearings, the coarse cleaning, the aluminum base, the steel ball retaining ring and the fine cleaning are carried out, and the metal grid can be placed at the bottom of the bronze sleeve used in the container.
B, rough when washing, eliminate grease or adhesions in oil with brush etc.. At this moment, if you roll the bearings in the oil, notice that the tumbling surface will be damaged by foreign objects.
C, when washing, slowly rolling in the oil, bearings must be carefully carried out.
General cleaning agent used for neutral aqueous diesel or kerosene, according to the demand of temperature and sometimes the use of lye etc.. No matter what kind of detergent you use, always filter and keep it clean.
Immediately after cleaning, apply antirust oil or antirust grease to the bearing.
2, view and discrimination
In order to judge whether the bearings can be removed from scratch, the accuracy of the scale, the rotation accuracy, the internal clearance, and the cooperation surfaces, raceway surfaces, cages and seals must be examined.
For inspection results, can be used by bearings or familiar bearing judge.
The criterion of discrimination varies according to mechanical function, principal degree, and viewing cycle. In case of the following damage, the bearing shall not be used from scratch, and it is necessary to replace it.
1) the cracking and defects of the bearing parts.
2) the stripping of the rolling surface of the raceway surface.
3, bearing defects identification methods
It is important to improve the productivity and economy of the bearings without identifying or guessing whether the bearings in the operation are defective or not.
The main methods of identification are as follows:
1) identified by sound
The demand for sound identification is extensive. It is necessary to train enough to recognize bearings, sounds, and non bearings. For this reason, we should try our best to do this task by hand. The sound of the bearing can be heard clearly on the shell by means of a listening device or a listening stick.
2) after operation temperature identification
The method is relatively recognizable and is limited to situations where the work condition is not changed. Therefore, it is necessary to record the temperature continuously. When things go wrong, not only does the temperature rise, it also changes irregularly.
3) identify by the condition of the lubricant
Bearings to lubricants sampling analysis, whether the degree of contamination, whether mixed foreign body or metal powder and so on. This method is particularly useful for bearings or large bearings that are not close to observation.
After proper timing, it is very important to improve the productivity and economy by finding faults early and avoiding accidents.
