Non-standard bearing damage causes and measures and fever several reasons

Non-standard bearing damage causes and measures and heat source of several reasons: bearing | last updated: - 2020 08 - 31 non-standard bearing damage causes and measures of non-standard bearing cannot be directly observed in the operation, but through the noise, vibration, temperature, lubricant, etc can be learned about bearing abnormal condition. The representative of the bearing damage cases; There are crack, crack defect part of the gap. The reasons are as follows: the impact of the host load is too large, spindle and bearing with large amount of interference; Also have larger stripping friction causes the crack; When installation precision is bad; Improper use, With copper hammer, card into the big foreign body) Friction and crack. Action: check the conditions of use, at the same time, set the appropriate interference and check material, improve the installation and use, check the lubricant to prevent friction crack. 2, the raceway surface of the metal strip surface stripping operation. After stripping is obviously concave and convex shape. Bearing roller and reasons both inner and outer ring raceway surface under periodic pulse load, resulting in a cycle change of contact stress. When stress cycle number reach the set value, the rolling element bearings, their work within or on the surface will produce fatigue peeling off. If the bearing load is too big, can make the fatigue. In addition, the bearing installation is not straight, shaft bending, also can produce the raceway stripping phenomenon. Non-standard bearing fever several reasons first, may be due to overload or overload, it is possible that a cooling fan problems now, such as there may be due to the heat generated by the mechanical friction, but the main problem is the bearing can be authentic, some users in order to lower prices and with low bearing, resulting in a bearing heating, hot, so that the present bearing burning phenomenon and so on. So, first of all, emphasize with authentic bearing. Second, second, to pay attention to adhere to the machinery lubrication, choose high quality high temperature lithium base grease, lithium base grease quality is also another major reason for bearing heating. In addition to your careful examination, assume is mechanical friction will be accompanied by noise, mechanical parts wear you said would be seen bearing loose, it should be bearing present problems, demand a change in the bearing. Advice with authentic bearing. Third, in the use of the bearing there are many unpredictable factors in the process of bearing caused by fever, should be early prevention, frequently change the fourth, non-standard bearing accomplished by testing the fever of bearing in many aspects.
