The application of non-standard bearing common problems

Common problems of the application of non-standard bearing source: bearing | last updated: - 2020 11 - 02 non-standard bearing common problems of the application of non-standard bearing the application of common problems. 1, main shaft bearing oil and coarse fine filter should be replaced in all normal application a year later. All the normal use of the sewage treatment plant oil filling register must have three layers of silk cloth. 2, pulley, the sand wheel spindle bearing when handling must be carried out under the condition of the sewage treatment plant work. The main shaft bearing in the case of negative pressure oil float. That does not harm the spindle bearing and dynamic pressure bearing. 3, the sand wheel spindle bearing sewage treatment plant before work investigation work stress and grinding wheel have negative pressure within the standard scale. 4, machine equipment mainly; Must first to stop using grinding wheel motor; After waiting for sand round piece stopped; To close the sewage treatment plant; Simple or damage the grinding wheel. 5, all parts of replacement of sewage treatment plants; You must first remove the import hydraulic hose joint; After the replacement parts; Fuel pipe with circulatory system need 15 ∽ 20 minutes to hook into the tubing up to the grinding wheel; Thus ensure the oil into the grinding wheel spindle bearing is based on refined ultraclean spindle bearing oil, can broaden the power of spindle bearing service life.

The rust is caused by poor installation, initial damage, and exhaustion of the pollutants, serious rust bearing damage. 3, all kinds of cracks, such as crack raw material, forging cracks, heat treatment process such as cracking and cutting, the cracks in the bearing after operation in the whole process, will become a source of stress and rapid expansion, lead to split bearing, bearing life and work safety coefficient is dangerous. In fact, in view of the key main use of bearings, bearing factory has the parts for 100% magnetic or radiographic inspection. 4, peeling and scale, these two shortcomings of some fusion with the base metal material is not stable, and its surrounding is usually not the same level with carburizing or lived in poor condition, carbon raw material is very easy to fall, indented or friction coefficient, the service life of bearing and precision is very bad. 5, the ball bearing riveting or welding welding quality, the key to observe the bolt head is deviation, tilt, relaxation, lack of meat, or 'all cut double-fold eyelid, welding welding parts is appropriate, spot welding is too big or too small, with or without welding welding not firm or welding welding stuck over the swivel causes too much.
