Stop check of rolling Angle contact ball bearing

Regular inspection of angular contact ball bearings ( 轴承) Seal is kept angular contact ball bearing in the best condition is very important work, 工作) 。 The most advantageous inspection time is arranged in regular outage inspection period. The importance of angular contact ball bearing: clean angular contact ball bearing and lubrication ( lubrication) It is important to clean. Bearing bearing lubrication method, divided into grease lubrication and oil lubrication. In order to make the bearing function well, first of all, to choose suitable for conditions of use, the purpose of lubrication method. If only consider lubrication and oil lubrication. However, grease lubrication can simplify the structure of bearing the surrounding of the special features, compare the pros and cons of grease lubrication and oil lubrication. Thin wall bearings manufacturer of angular contact ball bearings can match the optimal number of balls and the contact Angle of 30 °. They support radial load is higher than contact bearing deep groove ball bearings or four o 'clock, and can support comes from the same direction of axial load. In view of the special demand, need before check the cleaning machine ( machine) Surface, and then remove the angular contact ball bearings ( 轴承) The perimeter of the parts. Oil seal is very fragile parts, so need to carefully remove, not excessive force, and then carefully check oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace the bad oil seal will cause the damage of the angular contact ball bearing and lead to equipment ( shèbèi) Downtime. Check the lubrication ( lubrication) Agent of lubricant on friction between two fingers, if there is pollution, 污染) The thing, can feel out, or in the back with a thin layer of lubricant & have spent Then light to check. Replace the lubricant oil lubrication ( lubrication) Angular contact ball bearings in diarrhea after used engine oil, possible, impregnated with fresh oil and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, then spilled oil in addition to these, the oil before use it's best to filter it. Grease lubrication of angular contact ball bearings in replacing grease should be avoided with cotton material come into contact with any part of the angular contact ball bearing, because these residues fiber may ( 也许) Wedged in between the scroll and damage, especially the application of the small angular contact ball bearing is more need to pay attention to this problem. Covering exposed angular contact ball bearing, 轴承) Patrol angular contact ball bearing, don't let angular contact ball bearings are exposed to pollution, 污染) Content or moisture environment ( 环境) 。 If the job is interrupted, should with oil or similar materials cover paper plastic film machine. If without disassembly and may perform inspections under the situation of cleaning without masking of angular contact ball bearing, to coating with brush with oil ( 石油) Solvent ( whitespirit) Cleaning and dry with a lint-free cloth or with compressed air to blow dry, Note that ( 注意) Don't let the starting rotation angular contact ball bearing components ( 旋转) ） 。 With a little mirror, and the probe used in the similar to the dentist to check for angular contact ball bearing of the orbit plane, retainer and beads. If the angular contact ball bearings are not damaged, should be provided according to the original machine lubrication ( lubrication) Shows the advice of execution lubrication. Do not wash encrypted block or dust angular contact ball bearing; 'only to wipe ( 净化) 'its external surface. Provide precision leadscrew angular contact bearings, the previous: sliding bearing performance of the main causes of vibration next article: rolling bearing used on matters needing attention
