【 Experience sharing. Common 2020 - analysis of the causes of the damage mode and bearing 06 - 30 ( Henan runhua general equipment co. , LTD. ) Abstract: the mechanical operation of the bearing is commonly used to support parts, important parts is commonly used in mechanical equipment, its main function is to support the mechanical rotator, bear radial load, to make the bearings and keep its long-term performance into full play, must earnestly to do regular maintenance ( Regular inspection) 。 Through proper periodic inspection, do early detection of fault, prevent accident arrangement is very important to increase productivity and efficiency. This article is a common way of bearing damage and the reason is analyzed. Key words: bearing; Damage; To prevent a, improper installation, Accounts for about 16%) 01 installation when use brute force, directly with a hammer percussion bearing to bearing damage; Is the main cause of deformation. 02 installation does not reach the designated position, install a deviation or failure to the bearing, bearing clearance is too small. Inside and outside the circle is not in the same center of rotation, resulting in different heart. Suggestion: select the appropriate or professional bearing installation tools, installed with a special instrument to detect. Second, the poor lubrication ( Accounts for about 50%) According to the survey, poor lubrication is one of the leading causes of premature failure of the bearing. Main reasons including: failure to refill lubricant or lubricating oil; Lubricant or lubricating oil filling in place; Lubricant or improper lubricant selection; Lubrication method is not correct, and so on. Suggestion: to select the correct lubricant or lubricating oil, use the correct lubrication filling way. Third, pollution, Accounts for about 14%) Pollution can also cause premature bearing damage, pollution is refers to the dust, metal scraps into the bearing inside. 01 early to open the bearing packing before use, cause pollution; 02 when installation work environment is not clean, cause pollution. 03 bearing working environment is not clean, working medium pollution; Suggestion: before use it is best not to unpack the bearing; Keep the installation environment clean, when installation to use the bearing in cleaning; Enhance the bearing sealing device. Four, fatigue, Accounts for about 34%) Fatigue damage is a common way of damaged bearing. Common fatigue failure reasons might be: bearing long-term overload operation; Not timely maintenance; Improper maintenance; Equipment aging, etc. Suggestion: select the appropriate bearing type, timely replacement of bearing fatigue on a regular basis. The above is the most common kinds of cause the cause of early damage of the bearing; Cause the cause of early damage of the bearing is various, the above is a main consideration reason, sometimes may be integrated. If bearing selection, right installation properly in place, and choose the right lubricant lubrication way, the bearing can be normal work time very often. So the bearing early damage, may be caused by a variety of comprehensive factors. When bearing appear problem, we should be in accordance with this article damage possibility to screening, thus to solve it. Don't always investigate check suppliers all responsibility. （ Source: in machinery)
