Bearing storage
Author:
The storage of bearings must first fully consider the size and weight of the stored bearings, and secondly, consider the necessary handling space and equipment to ensure that the bearings will not be collided during storage and retrieval. Do not place the bearing directly on the ground.
Therefore, it is necessary to configure a proper shelf, and the bottom of the shelf should be 30cm higher than the ground. In the general packaging state, it varies with the storage environment, and the anti-rust effect is 13 years. When storage is required for nearly 10 years under special circumstances, the storage method can be immersed in oil such as turbine oil (as bearing lubricant).
(1) Work to install bearings
There are many ways to install the bearing, and the same work is done after installation. After the bearing is installed, the outer ring must be obliquely coated with lubricant for the bearing.
A. Application of lubricant
1. In the case of grease lubrication, apply lubrication to cover all roller surfaces, and restore the position of the outer ring after application.
2. For oil lubrication, coat all roller surfaces with oil, and restore the position of the outer ring after coating.
B. After coating, cover with plastic film to prevent dust.
(2) Precautions for disassembling the bearing
The disassembly of the bearing is carried out during regular maintenance or when the bearing needs to be replaced due to abnormal operation. When the bearings need to be replaced frequently during regular maintenance, the cause of the abnormality should be understood when disassembling the bearing to prevent the abnormality from recurring. At least the following items should be retained.
1. Collect and retain used lubricant.
2. Keep damaged bearings.
3. Keep records of abnormal events during operation.
4. Keep a record of the bearing condition during abnormal operation.
