The life of the bearing is closely related to manufacturing, assembly and use, and must be done well in every link. Only by paying attention to the above precautions when using non-standard bearings can the bearing be in the best operating state, thereby prolonging the use of the bearing life.
In order to ensure that the bearings are always running in good condition, regular maintenance and repairs are necessary, so as to prevent accidents before they happen, improve the production efficiency of the enterprise, and save costs. To engage in professional maintenance of bearings here, there must be a standard and systematic operation process, including a series of tests such as operating status, lubricant, regular disassembly, noise, temperature, etc.
After the bearing is pressed into the bearing, it should rotate flexibly without any sense of blockage. If there is obvious inflexibility in rotation, it indicates that the size of the shaft is too large and the tolerance should be lowered. If the bearing is pressed into the shaft and there is an obvious "sand" feeling when turning it by hand, it may be that the tolerance of the shaft is too large or the roundness of the shaft is not good. Therefore, when controlling the shaft and bearing tolerances, the roundness must also be controlled.
First, whether the bearing is installed correctly is directly related to the accuracy, life and performance of the bearing. Therefore, the installation and design department must fully study the installation of the bearing, analyze the structure of the bearing, etc. to ensure the normal operation of the bearing:
Clean the bearings and bearing-related parts; this is very important, be careful to clean them to prevent debris in them. Check the size and finishing of related parts; this requires some special tools to ensure the accuracy of bearing installation. Check after the bearing is installed; check whether the bearing is matched and whether there is any error. Supplying lubricant requires careful operation and is very important.
Second, the basic monitoring conditions of bearings:
Some professionals are needed, regular inspection of bearings, so that potential problems can be detected early, which will prevent unexpected machine stoppages, enable production to proceed safely, and increase factory productivity and efficiency. During the use of bearings, the basic external conditions of bearing operation should be monitored frequently, such as temperature, vibration and noise measurement, etc., so as to prevent problems before they happen.
Third, the alignment and alignment of the bearings:
These operations may accelerate fatigue and reduce the service life of bearings, and damage the service life of other machine parts. Furthermore, increased vibration and friction can greatly increase energy consumption and premature failure risk. However, after the bearing is installed, alignment can cause the bearing to be subjected to additional loads, friction and vibration if not carefully performed. As a result, the bearing will be damaged prematurely in advance, so it should be adjusted and straightened!
Fourth, relubrication of bearings:
If the bearing is considered lubricated, the lubricity of oil lubrication is dominant. But grease lubrication can simplify the features of the structure around the bearing. In the process of operation, the bearing requires correct relubrication. Lubrication can make the bearing run well. In order to make the bearing function well, first of all, it is necessary to choose a lubrication method suitable for the conditions of use and purpose of use, whether to use oil lubrication or grease Lubrication depends on the specific situation of the bearing!
Fifth, remove the bearing:
Use proper removal tools, which will help prevent damage to other machine components. Improper removal techniques may cause damage to the bearing. If the bearing reaches its end-of-life, it should be replaced. . Although the bearings can no longer be used, removing the original bearings correctly and replacing them with new ones in time can greatly promote the service life of the new bearings. Therefore, it is very important to replace the old and new ones. Professional personnel are required to carry out inspection operations
When the bearing is installed on the rotor for dynamic balancing, it is easy for iron filings generated during dynamic balancing to enter the interior of the non-standard bearing, so it is best to perform dynamic balancing before installing the bearing. For the convenience of assembly, some manufacturers apply some oil or grease in the bearing chamber to lubricate the bearing chamber during assembly, but it is often difficult for operators to control the amount well. Easy access to the interior of the bearing along the shaft. It is best not to apply oil or grease to the bearing. If it must be applied, it must be controlled so that there is no accumulation in the bearing chamber.
The bearings are used in accordance with the specifications and have been hit until the end of the bearing life. This kind of situation is relatively rare. Generally, SKF bearings are damaged due to various reasons during the operation and production process. In serious cases, the bearings are directly scrapped. These reasons are nothing more than three aspects: installation, use, and lubrication. , Commonly, it is caused by the jamming of the edge of the ring of the non-standard bearing. The main reason is insufficient lubrication or foreign matter. In response to these problems, we must first eliminate the cause of the accident, and use the environment, location, structure, etc. to investigate the reoccurrence of a similar accident and cause unnecessary trouble.
