There is a substantial solution to the bearing "running circle" problem that plagues China's machinery industry. It is widely promoted in the jaw crusher of the sand and gravel aggregate industry.
The so-called "running ring" of the bearing is that the outer ring of the bearing and the bearing housing or the inner ring and the shaft have a relative movement. The planetary gear of the wind power transmission has a running ring, which will cause irreparable damage to the gearbox. At present, there is no mature technology that finds the bearing "running circle" fault in advance and solves it in time. Most of the bearing "running circle" faults are confirmed after the transmission is damaged.
This technology has been promoted in China Sand and Stone Association, and has been used for many years in many mines in Fujian, Guangdong, Guangxi, Guizhou, Sichuan, Jiangxi and other provinces. It has been well received by users and is the only one in China. Meet the products of the People's Republic of China machinery industry standard JB/T1388-2015.
Overcoming the dynamic bearing does not run outside (inner) ring is similar to the method of overcoming the bearing running outer ring of the wind turbine, and in contrast, the working environment of the moving bearing is more severe, and the bearing is subjected to a greater torsional force. Therefore, the technology It is more convenient and practical to overcome the bearing outer ring problem of the wind turbine.
