When removing the bearing for inspection, first make a record of the appearance by means of photography and other methods. Also, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing.
Removal of the outer ring To remove the outer ring with interference fit, set several screws for the outer ring extrusion screw on the circumference of the outer casing in advance, and tighten the screw evenly while disassembling.
The purpose of lubricating rolling bearings is to reduce internal friction and wear of the bearing, prevent burning and sticking; prolong its service life; discharge friction heat and cooling, prevent bearing overheating, and prevent the aging of the lubricating oil; effect.
We all know that if the bearing temperature rises, it will cause bearing damage and affect the life of the bearing. How to deal with the rising bearing temperature, let the bearing sellers answer it. When the temperature of the bearing rises, it is necessary to check whether there is any abnormality in the swing of the lower bearing, whether it will make a harsh noise, and then check the lubricant to see if the lubricant has a strange smell. In the process of inspecting the bearings, we have to check them one by one from the aspects of rust and wear. Find out the cause of the bearing temperature rise through the bearing's operating frequency and other reasons. Test with modern tools to see if there is any abnormality in the structure of Zoucheng and the bearing. After we follow the above steps, we will understand why the temperature of the bearing rises.
Although the environment of large imported bearings is not good, some companies that are brand companies and companies that operate domestically imported bearings have increased rapidly in the previous year. It's much harder to build a brand today than it was a few years ago. Therefore, the imported bearing company still has to build its own brand: in terms of product development, it must be appropriate to spend today to make a difference, the difference must be "tall," and the difference must be the development idea of the big brand. Mass advertising in the media. This simple and rude method of brand building is now outdated. Imported bearing companies only need to have their own "fan group". They can be recognized by a segment of imported bearings. At the same time, there are some new additions that are worth encouraging imported bearing companies. For example, the whole house customization can see the rapid development of bearings. Under this spending trend, people's spending concepts have now changed, and individual needs are more and more focused. In recent years, many imported bearing companies have also begun to get involved in this one. The furniture made at the decoration site is not good in technology and not environmentally friendly. After the whole house is customized, there are good production equipment in the factory. The technology and environmental protection are also very good. The decoration site is only installed, which also reduces the time for consumers to decorate. . Of course, for imported bearing companies, when it comes to whole-house customization, it is necessary to deal with designers. The investment in factory production equipment must be more intelligent, and the customization requires precise data manipulation. In addition, under the new spending trend, import bearing companies must also continue to explore the form of sale. E-commerce is a big increase in the future. According to the forecast of China's E-commerce Research Center, in 2015, China ’s e-commerce planning for building materials products reached 205 billion, during which the online shopping plan increased by 249%, and the online shopping rate reached 17.5%. But now, China's imported bearing industry has not been able to qualify as an exceptionally successful company in terms of e-commerce. It lacks a leader, and e-commerce talents are relatively thin. Imported bearing companies need to be fully prepared to enter e-commerce.
Cleaning of non-standard bearings and inspection of non-standard bearings: Non-standard bearings are disassembled first, followed by complete visual inspection, cleaning, inspection and repair parts. 1. Before cleaning non-standard bearings, first check the oil quantity to identify and judge the effectiveness of the gas and oil system. Secondly check the physical and chemical status of the oil to see if the hair is dry, hard, caking, analysis, refinement, discoloration and other deterioration, determine and judge the rationality of the aging of the oil replacement cycle, adjust and change the oil change cycle and oil system . If necessary, test to find out oil, such as iron, copper, and dust pollution levels. 2. Bearing cleaning recovery Non-standard bearing cleaning Inspection and measurement of bearing components is very important. Before cleaning, try to wipe off the old dirty grease. Be careful not to put the non-standard bearings in operation, so as to avoid the foreign matter, the face of the non-standard bearings will crash during the driving process. Gently move to non-standard bearings to prevent injuries. 3. Non-standard bearing scrap records should have different meanings for statistical purposes. 4. Homework should be aluminum, non-standard bearings that are neither hurt nor as easy as rubber and difficult to pull, but also easy to keep clean. 5. The use of the cage's percussion method is cracked, as if judging the method, there is no crack in the porcelain bowl. 6. Zoning thickness is the basis of the waste cage and wear. 7. Cage outer circle and outer ring clearance of non-standard bearings are regarded as non-standard bearings. Speed must often be maintained in accordance with guidelines. 8. Defects are divided into three irregular levels so that proper repair measures can be taken to maintain them. Normal wear and tear, and judging errors refer to the same newline character. 9. Limitation of non-standard bearing defect fixation. 10. Defective non-standard bearings and oil lubrication, the assembly is directly related to quality. Assembly quality here includes traction gear that badly affects vibration, poor balance ability, assembly eccentric load, repair or variance of roller diameter of new non-standard bearing, grease, clean assembly quality is too poor, too poor, should be combined with symptoms, find and Eliminate faults and causes to ensure reliable non-standard bearings under normal operating conditions.
