The failure of YRT rotary table bearings is often caused by many factors. All influencing factors in the design and manufacturing process may cause the failure of the bearing, so it is not easy to judge. In general, it can be considered and analyzed from two aspects: use factors and internal factors.
The use factor mainly refers to whether the installation adjustment, use, and maintenance, maintenance, etc. meet the technical requirements. The installation condition is one of the first factors in the use factor. The bearing often changes in the stress state between the parts of the complete set of bearings due to improper installation. , To make the bearing run in an abnormal state and fail early. According to the technical requirements of bearing installation, use, maintenance, and maintenance, the load, speed, working temperature, vibration, noise, and lubrication conditions of the YRT turntable bearing in operation Carry out monitoring and inspection, find the cause of the abnormality immediately, investigate and restore it to normal. In addition, it is also important to analyze and inspect the quality of the grease, the surrounding medium, and the atmosphere.
The structure should be advanced while the design is reasonable in order to achieve a longer bearing life. The manufacture of bearings generally involves multiple processing procedures such as forging, turning, heat treatment, grinding, and assembly. The rationality, advancement, and stability of each processing technology will also affect the life of the bearing. Among them, the heat treatment and grinding processes that affect the quality of the finished bearing are often more directly related to the failure of the bearing. In recent years, the research on the deteriorating layer of the bearing working surface shows that the optimization of the grinding process is closely related to the improvement of the surface quality of the YRT rotary table bearing.
The smelting quality of bearing materials used to be the main factor affecting the early failure of bearings. With the advancement of metallurgical technology, the quality of raw materials has been improved. The proportion of raw material quality factors in bearing failure analysis has decreased significantly, but it is still the main cause of bearing failure. One of the influencing factors. The proper selection of materials is still an important factor that must be considered in bearing failure analysis.
