Regular maintenance of spherical roller bearing (regular inspection) can make the roller spare parts fully play and maintain its proper performance for a long time.
1, spherical roller bearing inspection and judgment
In order to determine the bearing to remove the ability to use, to check on its size precision, accuracy of rotation, internal clearance and mating surfaces, raceway, cage and seal ring.
With regard to the inspection results, it can be judged by the use of inertial bearings or proficient bearings.
Judgment criteria vary according to mechanical performance, importance, and inspection cycle. If the damage is below, the bearing shall not be reused and must be replaced.
1) fracture and defect of bearing parts of roller parts.
2) stripping of rolling surface of raceway surface.
2, spherical roller bearing cleaning
When the bearing of bearing parts is removed, the appearance record should be done by photography and other methods. In addition, it is necessary to confirm the amount of residual lubricant and to sample the lubricant, and then to clean the bearings.
A, bearing cleaning, coarse washing and fine cleaning, and the use of the bottom of the container put metal mesh.
Remove grease or adhesive in oil with a brush, such as B and rough wash. At this point, if the rotation of bearings in the oil, attention will be due to foreign bodies and other damage rolling surface.
C, fine wash, slowly rotating bearings in the oil, must be carefully carried out.
Commonly used cleaning agent is neutral non water diesel or kerosene, according to the need, sometimes also use warm lye, etc.. No matter what kind of detergent you use, always filter and keep clean.
Immediately after cleaning, rust oil or antirust grease is coated on the bearing.
