Description

Technical Field

[0001] The utility model relates to the technical field of couplings, in particular to a structure of a wind power coupling. Background Technique

[0002] A wind power coupling is an important device used in a wind turbine generator and a fan drive system. It is also a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms to rotate together and transmit motion and torque. The coupling in a wind turbine unit is used to connect the generator of the wind power generation equipment and the high-speed shaft of the gearbox, and can transmit a large torque with high stability.

[0003] At present, when the coupling is installed between the generator and the rotating shaft, the length of the coupling often does not match. The tiny structural gap will also cause the coupling to deform during operation. Usually, gaskets are added between the connecting shaft and the coupling. However, the inventor found that the current coupling is of an integral design and cannot adjust the installation gap, which is inconvenient to use. Therefore, we propose a structure of a wind power coupling. Content of the Utility Model
