Inspection And Judgment
In order to judge whether the removed bearing can be reused, it is important to check its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage and seal. Large bearings cannot be rotated by hand. Pay attention to the appearance of rolling elements, raceways, cages, and ribs. The higher the importance of bearings, the more careful inspection is required.
Causes of rolling bearing heating and its elimination.
Bearing accuracy is low: bearings with specified accuracy grades are selected.
The spindle is bent or the hole in the case is not the same: repair the spindle or the case.
Poor lubrication: Use the specified grade of lubricant and clean it properly.
Low assembly quality: improved assembly quality.
Bearing inner casing running ring: replace the bearing and related wear parts.
The axial force is too large: cleaning and adjusting the gap of the sealing ring is required to be between 0.2 and 0.3 mm, correcting the balance hole diameter of the impeller and verifying the static balance value.
Bearing damage: Replace the bearing.
