Abstract

The invention relates to the field of wind power generation devices, in particular to a magnetic coupling bearing system of a wind driven generator. The magnetic coupling bearing system comprises a shell, a rotating shaft system and outer magnetic rings. The shell is of a two-segment type, and is provided with a shell rotating shaft passing hole, a shell lubricating hole, shell outer magnetic ring installation holes and shell bearing cover flanges and used for installing a rotating shaft system and playing a role in support and transmission. The outer magnetic rings are installed between the two segments of the shell. The rotating shaft system is installed on the shell and provided with a rotating shaft, bearings, bearing covers and inner magnetic rings. After installation, the bearings are located at the two ends of the shell, and the inner magnetic rings are located on the middle portion of the rotating shaft, correspond to the outer magnetic rings and have the same magnetism. The outer magnetic rings wrap the peripheries of the inner magnetic rings. When the rotating shaft system rotates, because of the repulsive magnetic force effect of the inner magnetic rings and the outer magnetic rings, the bearings of the rotating shaft system can bear small force, a transmission system is protected, the breakdown rate of the wind driven generator is decreased, and economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of wind power generating equipment, in particular to a magnetic coupling bearing system of a wind power generator. Background technique [0002] According to the current research on fault diagnosis of wind power generators, it is found that bearings in wind power generators have a high failure rate. Since the wind turbine is powered by wind energy, it will cause pulsating impact when the wind turbine is running, so that the bearing system will be affected by the pulsating load, which is easy to damage the bearing. When the bearing is damaged, the maintenance cost is very high, which will cause a large economic loss. Therefore, it is of great significance to improve the structure of the bearing system and reduce the failure rate of wind turbines to improve the economic benefits of wind turbines. [0003] The existing wind turbine bearing systems all adopt traditional bearing structures, and general bearings...
