In order to give full play to ina bearings and maintain their due performance for a long time, regular maintenance (regular inspection) must be done
Through proper regular inspection, it is very important to find faults early and prevent accidents before they happen, so as to improve productivity and economy
Key factors affecting the service life of roller bearings for many rotating machinery products, their service life mostly depends on the service life of bearing components in key parts of the product
"Maintenance free" bearings are not one-way bearings that will never be damaged or fail, but that will not be damaged within a certain period of time
Here, the designers calculated the service life of the bearing ina
The service life of the bearing is greater than or equal to the overhaul cycle of the mechanical product, so that the bearing can be "maintenance free" and the used bearing can be replaced at the same time of the overhaul of the mechanical product without maintenance
1
When the ina bearing is removed for cleaning and inspection, the appearance record shall be made by photography and other methods first
In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing
a
The cleaning of bearings is divided into rough cleaning and fine cleaning, and a metal mesh frame can be placed at the bottom of the container used
b
During rough cleaning, remove grease or adhesion with a brush in oil
At this time, if the bearing is rotated in oil, be careful that the rolling surface will be damaged by foreign matters
c
During fine cleaning, rotate the bearing slowly in oil and carefully
The commonly used cleaning agent is neutral water-free diesel oil or kerosene, and warm lye is sometimes used as needed
No matter what kind of detergent you use, you should always filter it to keep it clean
After cleaning, coat the roller bearing with antirust oil or grease immediately
2
Inspection and judgment in order to judge whether the removed bearing can be reused, we should focus on the inspection of its dimensional accuracy, rotation accuracy, internal clearance, as well as the mating surface, raceway surface, cage and sealing ring
The inspection results can be judged by those who use inertia bearings or are proficient in bearings
The judgment standard varies according to the mechanical performance, importance and inspection cycle
