Play and its performance to maintain long-term to make the bearing fully, must cogent do regular maintenance (check)
Through regular check for proper, do early detection of failure, to prevent accidents, is very important to improve the productivity and economy.
1, cleaning
Remove the bearings when the examination, using methods such as photographic appearance record. In addition, to confirm that the remaining amount of lubricant and lubricant sampling, and then cleaning bearings.
A bearing cleaning, rough cleaning and washing, and the metal frame at the bottom of the container placed on the use of.
B, rough when washing, use the brush in the removal of grease or oil adhesion. At this point if oil bearing, attention will be due to foreign bodies such as damage the rolling surface.
C, sperm washing, slowly rotating bearings in oil, be careful.
Cleaning agents are commonly used as neutral without water diesel or kerosene, sometimes using temperature as needed, such as lye. No matter what kind of cleaning agents, are often filtered clean.
After cleaning, immediately on the bearing coating antirust oil or antirust grease.
2, examination and judgment
In order to determine the bearing removed can re-use, to check on the accuracy of rotation accuracy, internal clearance, and the mating surfaces, raceway, cage and sealing ring.
About the examination results, can be judged by the bearing or bearing are used in.
Criteria based on the mechanical properties and the important degree and the inspection cycle and different. If the following injury, bearings shall not be re used, must be replaced.
1) bearing parts of the fault and defect.
2) the raceway surface rolling surface stripping.
Fault identification method, bearing 3
Not by removing the inspection, bearing can be identified or predicted operation without failure, is very important to improve the productivity and economy.
The following major identification method:
1) identified by voice
Recognition of the need to have rich experience through sound. Must be adequately trained to identify the bearing and non bearing sound sound. Therefore, should as far as possible by the person for the job. Listening stick attached to the shell bearing hear a listening device or.
2) identified by the working temperature
The method of comparison recognition method, used only in running condition, less change of situation. Therefore, the need for continuous recording of the temperature. When a fault occurs, not only temperature, irregular changes also occur.
3) through state recognition of lubricants
Analysis on lubricant sampling, judging by the pollution level is mixed with foreign body or metal powder etc.. The method cannot be close to the observed bearing or large bearings are particularly effective.
