Abstract

The embodiment of the invention provides a wind generating set. The wind generating set comprises blades, a power generator and a cabin, wherein the root parts of the blades are connected with a connecting shaft; the connecting shaft is in rolling connection with the front end of the cabin through a rolling connecting device; the power generator is arranged in the cabin; and the connecting shaft drives the rotor of the power generator. The wind generating set provided by the embodiment of the invention can reduce design and manufacturing requirements, on a low-speed shaft, of the wind generating set (can cancel the low-speed shaft to adopt a direct-drive way to drive), and distributes load borne on the low-speed shaft onto the cabin through the blades, so that blade mechanisms of the windgenerating set are more reasonable, the transmission effect is more stable, and the service life of the wind generating set is prolonged.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generating set. Background technique [0002] A wind turbine usually consists of a nacelle, a tower, a yaw device, and an impeller. The impeller of a non-direct drive wind turbine is connected to the nacelle through a low-speed shaft in the center of the impeller, thereby driving the generator rotor in the nacelle to generate electricity. The low-speed shaft not only serves as the connecting part between the impeller and the nacelle (the gravity of the impeller is transmitted to the nacelle through the low-speed shaft), but also serves as the driving part of the generator rotor to generate electricity. During the operation of the wind turbine, the low-speed shaft not only bears the shaft It also bears the gravity load perpendicular to the axial direction of the low-speed shaft, and the load perpendicular to the axial direction of the low-speed shaft cau...
