Method to avoid premature bearing use undeserved damage

General use of rolling bearing, smaller because of friction, less damage, so the service life of rolling bearing fatigue life can be achieved. But if in use process due to the accident, may also cause early damage, thus cannot be used. Generally not because of fatigue life of unusable due to we become early damage, or directly call using fault or accident. Usually develops in installation and use of rolling bearing, lubrication, and so on and so forth. The structure of the rolling bearing; Usually different parts structure is different, the processing technology is different, if used on different parts don't match rolling bearing, so sure it is easy to make the rolling bearing damage. Improving processing technology; Rolling bearing in the process of heat treatment process is best to use the lower quenching heating temperature, the appropriate to extend the time of heat preservation, such doing can improve the bearing alloy concentration, can enhance the impact toughness of bearing. Improved process monitoring method; To promote the quality improvement of machining. Such as improve circulation channel curvature position monitoring, to improve the overall performance after auto bearing assembly, improve rolling bearing working condition. Preventive measures 1, measure the body main bearing hole alignment and roundness, and measuring the crankshaft beat at the same time, by selecting the thickness of the bearing, lubrication gap evenly. Mix bearing shell scrape research method may be adopted. 2, improve the quality of bearing maintenance and assembly, strictly control the quality of connecting rod. All requirements of the new and old connecting rod measuring the parallelism and the degree of distortion, unqualified connecting rod assembly; ban Bearing the tile edging of the upper and lower two pieces of bearings shall be within the above 30 - bearing seat plane 50 mm, to ensure that the bearing is not loose; When assembling crankshaft prevent skewed and uneven bearing bolt torque in order to avoid bending deformation of the crankshaft. Environmental purification assembly site, make cylinder liner dust cover, to ensure the purity of the diesel engine assembly. 3, the reasonable selection and filling lubricating oil, and ensure clean.
