Non-standard bearing steel smelting surface decarburization layer requirements and processing method of internal failure

Non-standard bearing steel smelting surface decarburized layer requirements and internal failure treatment method source: bearing | last updated: - 2020 09 - 18 of non-standard bearing steel smelting surface decarburization layer requirements in non-standard bearing material standard of the decarburization layer of the steel surface has strict rules, if the surface decarburization layer beyond the prescribed scope of the standard, and before the heat treatment process, and there is no clear away all the, is in the process of heat treatment quenching is prone to quenching crack, cause scrap parts. Other requirements in non-standard bearing steel material standard of non-standard bearing steel smelting method, hardness, fracture, oxygen content and annealing residual elements, spark test, delivery status, identity, and so on have strict requirements. Non-standard bearing inner failure treatment 1, non-standard bearing damage. Check ball of ball bearing or bearing bush of ball bearing is damaged. If there is any damage should be repaired or replaced. 2, lubricating oil with impurity, too dirty, oil ring stuck or brand is wrong. Should check the reason stuck in oil, repair, when oil viscosity is too large, should change the lubricating oil. 3, non-standard bearing indoor short of oil. Should add grease with two-thirds of the oil level of oil chamber or add lubricant to the standard line. 4, non-standard bearing grease in the jam is too much, the eccentric bearing lubricating oil temperature too low or too high. Should remove excessive grease in the rolling bearing, or the oil indoor full of grease to 2/3. 5, bearing and shaft, bearing and end cover with too loose or too tight, too tight will make the whole deformation eccentric bearing, too loose prone to 'run'. Bearings and shaft too loose when the journal can be coated metallic paint, the tight to processing; Bearing a loose end cover set close together with end cover, the tight to processing. 6, two of the motor end cover or didn't assembled bearing cover, it is usually not parallel, overall eccentric bearing is not in the correct position. The two end cover or stop bearing cover mouth flat, tighten the bolt. 7, belt too tight, too loose or bad coupling assembly. Adjust the belt elasticity; JiaoZheng coupling. 8 and maintenance in the wrong bearing type. To replace the right type of bearing as soon as possible.
