The main task of angular contact ball bearing failure analysis is to find out the main factors causing bearing failure based on a large number of background materials, analysis data and failure modes, so as to propose improvement measures in a targeted manner, extend the service life of bearings, and avoid TIMKEN bearings. A sudden early failure occurred.
First of all, the structural design is reasonable and advanced, so that there will be a long angular contact ball bearing life. Bearings are generally manufactured through multiple processes such as forging, heat treatment, turning, grinding and assembly. The rationality, advancement and stability of each processing technology will also affect the life of the bearing. The heat treatment and grinding processes that affect the quality of the finished TIMKEN bearing often have a more direct relationship with the failure of the bearing. In recent years, research on the metamorphic layer of bearing working surface shows that the grinding process is closely related to the bearing surface quality.
1, pay attention to the installation of the bearing
Whether the bearing is installed correctly affects accuracy, life and performance. Therefore, the design and assembly department should fully study the installation of bearing products. I hope to install according to the operating standards. The items of the job standard are usually as follows:
(1) cleaning the bearing and bearing related components;
(2) Check the size and finishing of the connected components;
(3) installation;
(4) Inspection after installing the bearing;
(5) Supply lubricant. Carefully do the five steps of bearing installation
2, alignment, straightening
After the TIMKEN bearing is installed, alignment may result in additional loads, friction and vibration of the bearing if not carefully aligned. These can accelerate fatigue and reduce the service life of bearing products and can damage the life of other machine parts. In addition, increased vibration and friction can greatly increase energy consumption and risk of premature failure.
3. Basic condition monitoring
During use, the basic external conditions of the bearing operation are often monitored, such as temperature, vibration and noise measurements. Bearing experts point out that these regular inspections will identify potential problems early and will prevent unexpected machine stops, enabling production plans, increased plant productivity and efficiency.
