Regular maintenance of SKF bearing stainless steel cleaning and inspection method of knowledge - bearing

Need to stress is that link stainless steel bearing lubrication and cleaning is very important. So when we raid was carried out on the bearing, the draw clean SKF bearing, and then remove the perimeter of the bearing parts. It is cowardly of oil seal parts, fruit and was raided and demolition demolition need cockiness special be careful, don't be too much work, so that form the damaged parts. Then carefully the raid of bearing oil seal and its surrounding parts, if not present adverse symptoms, be sure to switch off, bad seal will result in bearing damage, make the stainless steel bearing cloud differences and the formation of a equipment downtime. Diameter of axle and bearing shell direct contact to prevent adhesion formation and boundary lubrication performance. Factors influencing the friction pair friction compatibility of materials is: ( 1) As a deputy to the difficulty of the composition of alloy materials metallurgy. ( 2) Materials and affinity of lubricant. ( 3) Become vice material in the absence of the friction factor of lubrication condition. ( 4) The microstructure of materials. ( 5) Thermal conductivity of materials. ( 6) The size of the material surface energy and the characteristics of the oxide film. This part of the process is imported bearings of the main working procedure, the process of inspection is the main difference in locomotive repair industry manufacturing industry. Into the repairing stainless steel bearing can continue to use, how to satisfy the use requirement, will be central to this part of the process to solve the question. Before cleaning, first check the status of grease to keep basin and to identify and determine the effectiveness of the current refueling, fill oil system. For hair second oil state of physical and chemical examination, qian, harden, agglomerate, oil analysis, thinning, color and other degenerative conditions, to determine and judge the rationality of the aging oil change cycle, adjust the oil change period and fill oil system. SKF bearing cleaning degree is to restore a stainless steel bearings and bearing parts inspection measurement necessary link. To try to erase the old dirt grease before cleaning, be careful not to turn the bearing in the process of operation, to avoid collapse into impurities in the process of strain rolling working face; Move the bearing to should take put down gently, to prevent bruising. Cleaning work is often done in diesel oil pool, diesel heated to 80 - - - - - - - 90 t, the pump pressure, circulation bearing. Please wash the pool bottom should have a metal net, prevent SKF bearing from falling into the pool after. Pool of diesel filter regularly, add new oil, clean up the sunken temple, to maintain the purity of the diesel meet requirements in the process. Cleaning fluid with belt mixed corrosion medium is prohibited. Traditional flush or high temperature ( With a mixture of steam and water spray, slightly more than the oil temperature drop point) Cleaning process, as long as can satisfy the requirement of cleaning quality, new things, need not deliberately. Cleaning quality of imported bearings, is the clean degree scale yes stainless steel bearing. Railway vehicle department after repeated research, the real face, determine the technology standard of pile is SKF bearing in thousands clean gasoline, after cleaning with pool paper filtration, drying, weighing, its residual ash content is not more than 20 mg, in railroad engineering department to facilitate control.
