Metallurgical quality of the bearing material used to be the main factors affecting premature failure of bearings. As metallurgy advances in technology, improvements in the quality of raw materials. Raw materials quality factors in the failure analysis of bearing the proportion has decreased significantly, but it still is one of the main factors affecting the bearing failure. Adequacy selection is still bearing failure analysis of factors must be taken into account.
Bearing maintenance includes: routine maintenance and lubrication of the bearings and fuel oil on a regular basis, preventive tests and periodic calibration of precision, bearing corrosion protection and level of maintenance.
Daily maintenance of bearings referred cases, refers to operatives bearing each day before use, used and during use must be carried out after work.
The daily maintenance of the bearing is to reduce wear, keep the bearings are in good technical condition of Foundation work. Daily maintenance maintenance of basic requirements is: operation who should strictly by practice for using bearing, often observation bearing running situation, and in class Qian, and class Hou fill in records; should maintained bearing full, annex neatly, security protection device complete, line, and pipeline full lossless; to often wipe bearing of all parts, maintained grease, and no leak oil, running flexible; should by normal running of needs, timely note oil, and for oil, and maintained oil smooth; often check security protection device is complete reliable, guarantee bearing security run.
Manufacture of bearings typically after forging, heat treatment, machining, grinding and assembling multiple processes. Rationality, advanced processing technology, will also affect the stability of the bearing life. Which affect the quality of products bearing heat treatment and grinding operations, often has a more direct relationship and bearing failure. In recent years on the Japan bearing working surface degenerating layer study showed that close to grinding and surface quality of bearing.
Cleaning: bearing both within and outside the clean, no dust, no black stain rust; the moving parts and no grease, without napping, bumps, scratches; each part does not leak, air leak, leak oil; chips. Lubrication: according to requirements of various parts of the bearing lubrication, fueling, changing the oil on time, oil conform to the rule, complete oil pot, guns, oil cups, clean linoleum, oil lines, oil attention getter, oil flow. Security: requirements strictly introduced will people, and will machine, and will post duties and shift system; operation workers should familiar bearing performance, and structure and principle, comply with practice for, correct, and reasonable to using, carefully to maintenance maintenance; various security protection device reliable, by pressure container by provides time for prevention sexual test, guarantee security, and reliable; control system work normal, grounded good, power conduction cable by provides time, and requirements into prevention sexual test, guarantee transmission security, and normal, no accident hidden.
Day-to-day maintenance, only the "severity" of the order, the correct, rational use, careful maintenance, careful management, and earnestly strengthen the inspection before and during use and after use, to eliminate hidden dangers, serious and of high quality in a timely manner, troubleshooting. To do a running record, guarantee the correctness and completeness of the original information, credentials. Require operators can focus on common faults of bearings, making recommendations for improvement, and, together with maintenance workers, take the appropriate measures, improved the technical condition of the bearing, reducing failure frequency and eliminate accidents, achieve the purpose of maintenance.
