The application of the primary means that the device adjustment, application protection, protection and repair can meet the skill needs. The device condition is one of the primary elements in the application of the element; the imported bearing often attracts the force between the parts of the whole bearing due to the improper installation of the device. The situation changes; the bearing operates under abnormal conditions and fails prematurely. According to the skill requirements of the imported bearing device, operation, protection and protection; the load, the rotational speed, the operating temperature, the oscillation, the noise and the smoothness of the bearing in the operation Conditions are monitored and viewed; abnormalities are found immediately; the adjustments are made; the rehabilitation is normal. In addition, it is also important to analyze the quality of the smooth grease and the surrounding medium and atmosphere. How to judge the quality of the imported bearings? Please see the analysis of "How to judge the quality of imported bearings".
The connotation elements mainly refer to the three major factors of the quality of imported bearings, such as structural depiction, production process and data quality.
First of all; the structural description is reasonable and has advanced; it will have a long bearing life. The bearing is usually produced through multiple processing steps such as casting, heat treatment, turning, grinding and installation. The rationality of each processing technology. The advanced nature and stability will also affect the life of the bearing. The heat treatment and grinding process that affect the bearing quality of the product are often more directly related to the failure of the bearing. In these years, the research on the external deformation layer of the bearing operation indicates The grinding process is closely related to the quality of the bearing appearance.
The metallurgical quality of imported bearing data was once the primary factor affecting the early failure of rolling bearings. Following the advancement of metallurgical skills (such as vacuum degassing of bearing steel); the quality of the original data was improved. The original data quality factor accounted for in bearing failure analysis. The proportion has been significantly reduced; but it is still one of the primary factors affecting bearing failure. Whether the selection of materials is appropriate or not is still an essential element for bearing failure analysis.
The primary task of the analysis of the failure of imported bearings is based on a lot of set data, analysis data and failure modes; find out the primary factors that form the bearing failure; so as to propose an improvement method in an aligned manner; extend the service life of the bearing; Early failure of the hair.
