Problems solved by technology
In addition, the current wind turbines basically operate under the influence of the complex wind resource environment outside, and the load on the blades is very large under full power and extreme conditions, which causes the main shaft bearing to run for a long time under large radial force and axial force. Under the condition of high force, the friction heat of the spindle bearing will be large, and the temperature of the bearing will be high after a long time of operation.

The invention provides a bearing cooling system, a bearing cooling method and a wind generating set. The bearing cooling system comprises an outer ring cooling system and an inner ring cooling system, wherein the outer ring cooling system comprises a first heat dissipation assembly which is installed at the position corresponding to the outer side wall of a bearing outer ring; and the inner ring cooling system comprises a second heat dissipation assembly which is installed at the position corresponding to the inner side wall of the bearing inner ring. According to the bearing cooling system, a bearing of the wind generating set can be cooled, and the temperature of the bearing is reduced.
Description
technical field [0001] The present invention relates to the technical field of motor cooling, and more specifically, relates to a bearing cooling system for cooling a bearing of a wind power generating set, a bearing cooling method and a wind generating set. Background technique [0002] Wind energy is an open, safe, renewable and clean energy. At present, the utilization of wind energy has been paid more and more attention. A wind turbine is a power generation device that relies on capturing wind energy and converting kinetic energy into electrical energy. In modern large-scale wind turbines, as the power generated by a single machine increases, the torque of the wind turbine increases, and the load on the rotating parts also increases. For example, the work of the main bearing of the generator supporting the impeller The load increases. In addition, the current wind turbines basically operate under the influence of the complex wind resource environment outside, and the l...
