According to the transmission chain structure for the wind generating set and the wind driven generator, a main shaft and a gear box are connected through a coupler, on one hand, the coupler has the axial and radial compensation effect, and axial and radial deformation and manufacturing and assembling errors of a shaft system under the wind load condition can be absorbed; the influence of shafting deformation on gear box planetary stage and gear ring gear meshing is reduced, and the failure risk of the gear box is greatly reduced; and on the other hand, when part of components in the transmission chain structure are damaged and need to be maintained, the coupler and the related components can be detached for lower tower maintenance, overall detachment is not needed, the maintenance cost is saved, and the transportation and hoisting difficulty is lowered. In addition, the supporting ring is provided with the first open hole, so that an operator can conveniently assemble and disassemble all parts of the transmission chain structure and overhaul the coupler diaphragm through the first open hole, the structure is simple, and operation is convenient.
Description
technical field [0001] The invention relates to the technical field of wind power generators, in particular to a transmission chain structure and a wind power generator for a wind power generator. Background technique [0002] At present, there are mainly four types of drive chain structures commonly used in wind turbines: three-point support shafting, two-point support shafting, single-point support shafting, and direct drive drive chains. [0003] Among them, the transmission chain using high-speed gearbox + doubly-fed generator / squirrel cage generator / high-speed permanent magnet generator structure is also called high-speed gearbox transmission chain; the transmission chain using low-speed permanent magnet generator or low-speed electric excitation generator Also known as a direct drive transmission chain; a transmission chain with a medium-speed gearbox + medium-speed permanent magnet / double-fed generator structure is also called a semi-direct drive transmission chain. ...
