Analysis of four row cylindrical roller bearing used in favor of the cause of the failure of malfunction

Imported bearing failure is often the cause of many factors, all the influence factors of design and manufacturing process will be associated with the failure of four row cylindrical roller bearings, analysis it is not easy to judge. In general, generally can be used from the two aspects of factors and internal factors considered and analyzed. Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. Installation conditions is to use one of the primary factor of factors, four row cylindrical roller bearings are often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state run and early failure. According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. In addition, analyze the grease and the surrounding medium, the atmosphere quality inspection is also very important. 1. Such as hear the noise from the imported parts, first of all, it is important to find the location of the noise occurs. There are many possible noise of moving parts, may also be some rotating parts and no contact with rotating parts. If confirmed is the noise in four row cylindrical roller bearings, may have been damaged, need to change. 2. Because before the similar working conditions, leading to the invalid on both sides so even a bad one, also recommends replacement in pairs. 3. Import is sensitive, under any circumstances need to use the right methods and with the right tools. In the process of storage and transportation and installation, bearing components cannot be damaged. Need a larger pressure, so I need a special tool. Be sure to refer to the instruction. 4. When installation should be clean and neat environment, tiny particles into will shorten the service life of four row cylindrical roller bearings. Replace when it is very important to maintain a clean environment. Not allowed to use hammer percussion, careful not to fall to the ground, Or similar misconduct) 。 Before installation should also check the status of the shaft and housing, even minor wear can also lead to cooperate with bad, causing damage. Imported bearing materials metallurgy quality was the main factor affecting the premature failure of the rolling bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in the bearing failure analysis share has declined obviously, but it is still four row cylindrical roller bearing failure of one of the main influence factors. Select material adequacy is still bearing failure analysis factors must be considered. The main task of the imported bearing failure analysis, it is based on a lot of background material, analyze data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, extension of four row cylindrical roller bearing, avoid premature failure of the bearing of the sudden.
