Background
The existing wind power coupler is used for connecting a gear box and a generator, not only plays a role of transmitting torque, but also can be disconnected when the torque reaches a certain numerical value, so that a wind turbine generator is protected. When the generator set is short-circuited or overloaded, the overload torque overcomes the friction force and automatically slips, so that the safety of the wind turbine generator set and the coupling is protected. When the overload condition disappears, the automatic connection can be realized, so that the unit can normally operate. The continuous and stable transmission of torque and motion between the two shafts is realized. The slip protection device and the main shaft of the coupler in the prior art are of an integrated structure, once the slip protection device and the main shaft of the coupler slip, spare parts are high in cost, and the workload of field replacement is large.
The connection of the gear box and the generator is realized by connecting a common wind power coupling at the high-speed shaft end of the existing wind turbine generator. Due to the fact that the wind turbine generator is poor in operating environment and complex in working conditions, the compensation capacity, the torsional strength, the dynamic balance performance, the stability and the like of the wind turbine coupler in all directions play an important role in the service life of the wind turbine generator. The diaphragm group of the existing wind power coupler has two structures, the first one is a grouped metal diaphragm structure, two groups of diaphragm structures are respectively adopted at two ends of a wind power coupler intermediate body, four groups are provided, and a plurality of metal diaphragms in each group are respectively installed with a glass fiber reinforced plastic intermediate pipe and a connecting disc into a whole through structures such as bolts, pin sleeves and the like, so that the grouped metal diaphragms can have the conditions of gaps, preload and the like caused by installation in the installation process, and are inconvenient to assemble and high in cost; the second is a head-to-tail connecting rod splicing structure: the structure is that a plurality of epoxy resin membrane groups are respectively arranged at two ends of the wind power coupler, and the rubber connecting rod type is adopted to realize the compensation function of the coupler in all directions through the rubber connecting rod designed by the module, but the high polymer epoxy resin has high cost, so that the manufacturing cost is very high.
