Many reasons plastic bearing failure, all design and manufacturing process factors are associated with failure of Giantshk bearings, analysis is not easy to determine. In general, generally can be from two aspects of use and internal factors into consideration and analysis.
Using the factor mainly refers to the installation and adjustment, maintenance, maintenance repair and other compliance with technical requirements. Installation conditions is one of the leading factors in the use factor, Giantshk bearings are often caused by the installation of inappropriate stress state between the various parts of the complete bearing change, bearing an abnormal state operation and early failure. According to the requirements of the bearing installation, use, maintenance, maintenance technology, which acted on the bearing in operation of the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found abnormal immediately find reasons to adjust, restore normal. In addition, the grease quality and atmosphere surrounding media, analysis is also very important.
Internal factors mainly are the three major factors that structure design, manufacturing process and material quality decides the quality Giantshk bearing.
First of all, reasonable structure design of both advanced, there will be a longer bearing life. Manufacture of bearings are generally after forging, heat treatment, machining, grinding and assembling multi-channel processes. Rationality, advanced, stability of the machining process can also affect the service life of bearing. The effect of heat treatment and grinding process quality of Giantshk bearings, often has a more direct relationship with the bearing failure. Study on bearing surface modification layer of work in recent years, the relationship between grinding and surface quality of bearing close.
The metallurgical quality of plastic bearing material is the main factor affecting the early failure of rolling bearings once. With the metallurgical technology (such as vacuum degassing of steel bearing) progress, improved quality of raw materials. Raw materials quality factors of failure analysis of the proportion has decreased significantly in the Giantshk bearing, but it is still one of the main factors of bearing failure. Proper selection is still bearing failure analysis must be considered.
The main task of failure analysis of plastic bearing, is based on the analysis of data and failure forms of the large amount of background material, and identify the main factors causing bearing failure, so as to put forward the improvement measures, extending the service period of Giantshk bearings, avoid unexpected early bearing failure.
