Refrigeration compressed bearing is broken? What kind of can also repair? What are the necessary have to throw?

How to distinguish the bearing can use again and demand a change in the bearing defect discrimination bearing can use again, according to the damage degree of bearing, mechanical properties, importance, and operating conditions, check the relevant factors such as cycle to resolution. But check if found any of the following defects, the bearing can't continue to apply, demand a change in the new bearing. A, inner ring and outer ring, rolling body, insist on shelf in the wild have crack or gap. B, ring, rolling body of arbitrary has a fracture. C, rolling surface, guard, has obvious scratches on rolling element. D, or rivets loose obviously. Stick to wear is obvious. E, raceway surface, rust or scar on rolling element. F, raceway surface and rolling body has serious indentation or bruised. G, inner ring diameter or outer diameter surface has obvious creep. H, and obvious discoloration due to overheating. I, of smooth grease sealed bearing seal ring or dust cover seriously damaged. Bearing comprehensive repair? Bearing comprehensive repair including attack damage of bearing after cleaning, collapse, inspection, roller grinding or changing the inside and outside the circle, the new rolling system build/original grinding roller, rolling restructuring in, assembling, clearance adjustment and inspection packing and so on comprehensive strict repair process, to ensure that the repaired bearing can reach new bearing performance request. What kind of bearing can repair? Main needle bearing comprehensive repair of the large size of rolling bearings (high relative new capital Such as transmission bearings, work roll bearings, bearing roller bearing and roller mill bearings, etc. ) 。 Of course, small aperture bearing is also able to repair. Repair technical difficulties if say bearing repair what exists in the technical difficulty. Basically able to think, just is rolling bearing is to be able to repair. Need to repair the bearing device size we don't do change, because if change its size, the bearing cannot be normal device. However, due to repair required some machining disposal, bearing on the internal dimension will have change, we can through other method, the grinding amount of compensation. After repair of bearing can really be good as new? However, after the repair of bearing can really good, such as the new? Baosteel staff introduced, we have a belongs to own a detection method. After repair of the bearing and the new bearing by detection, makes no difference. Now, many industries in bearing repair has become an international enterprise, Including steel, metallurgy, energy, paper making, cement, airlines and car racing, and many other industries) The important measures to reduce capital, and the bearing repair for their decreased consumer devices operating capital, frugal consumption equipment bearing purchasing cost can reach 20% 90%. Provoked bearing damage reason all damage of the bearing is not able to repair, but bearing in thinking about every damage repair or change before the new bearing, necessary for evaluation of its level of damage reason and stop to prevent or reduce the damage once again. Provoked the cause of bearing damage a lot, such as improper installation, filth from invading as well or water intrusion is a common reason for many early bearing damage. Here are some common damage reason analysis of large size bearing and the corresponding can extend bearing life preventive measures. 1 improper operation device, improper operation or remove may have provoked frame deformation or defect prevention measures: use appropriate operation, installation and removal tools. 2 smooth plentiful smooth not energetic or inappropriate can cause components abrasion or serious bearing deformation preventive measures: improve the smooth system, timing supplement or a change in smooth agent properly. 3 touch water can cause bearing components rust and corrosion pitting and rust. After corrosion damage of bearing can cause peeling precautions at work: regular inspection seal, ensure good sealing effect, correct storage of bearings. 4 current bearing rotates the electricity can cause to present a groove or notch. Bearing static, electrical grounding improper operation will incur slight burn prevention measures: outside of bearing parts before welding through proper grounding connection to reduce or prevent electric current through a bearing. 5 outside material wear particle pollution and debris intrusion can cause the bearing face precautions: wear, abrasion and sag from invading particles and debris, smooth change agent, check the sealing system. 6 eccentric can cause geometric eccentricity, inclination, or excessive load stress concentration or appearance scaling prevention measures: accurate machining housings and over the shoulder.
