Many determinants of EDA bearing service life span, but generally can be divided into two types, one is the internal factor (factor of bearing), another is bearing the external.
The main roller bearings inside factors including structural design, manufacturing process and material quality such as the three major factors.
EDA bearings manufacturing generally after forging, heat treatment, machining, grinding and assembling multi-channel processes. However, rationality, advanced processing technology, the stability will also affect the service life of bearing. The quality of the finished product bearing heat treatment and machining processes 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.
Metallurgical quality of EDA bearing material was the main factors affecting the early failure of rolling bearings. With the metallurgical technology (such as vacuum degassing of steel bearing) progress, improved quality of raw materials. Raw materials quality factors has been a marked decline in the proportion of failure analysis of spherical roller bearing, but it is still one of the main factors of bearing failure. Proper selection is still bearing failure analysis must be considered.
The use of EDA bearing mainly refers to the installation and adjustment, maintenance, maintenance repair and other compliance with technical requirements. According to the requirement of bearing installation, use, maintenance, maintenance technology, which acted on the bearing in operation, speed, load, temperature, vibration, noise and lubrication condition monitoring and inspection, found abnormal immediately find reasons, adjustment, restore normal. Installation conditions is one of the leading factors in the use factor, spherical roller 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 ending life of internal factors are mainly three factors refer to structural design, manufacturing process and material quality determine the bearing the quality of the.
Metallurgical quality of EDA bearing materials are the main factors influencing 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 has been a marked decline in the proportion of bearing failure analysis, 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 EDA bearing service life, is based on the analysis of data and failure forms of the large amount of background material,, identify the main factors causing bearing failure, so as to put forward the improvement measures, to extend the service period of spherical roller bearings, avoid bearing early failure of sudden onset.
