[0002] The wind turbine gearbox is an important mechanical component in a wind turbine generator set. Its main function is to transmit the power generated by the wind rotor under the action of wind to the generator and make it obtain the corresponding speed. Traditionally, the elastic support assembly of the wind turbine gearbox generally includes a U-shaped frame, an upper crossbeam installed on the U-shaped frame, a lower elastic member installed at the center of the U-shaped frame, and an upper elastic member installed at the center of the upper crossbeam. The U-shaped frame and the upper crossbeam are respectively provided with adjustment bolts capable of adjusting the upper and lower elastic members.

[0003] The patent document with announcement number CN205117624U discloses an elastic support assembly for a gearbox of a wind turbine generator set. It includes an upper seat and a bottom plate, and four columns with rectangular cross sections located at four corners of the upper seat and the bottom plate are connected between the upper seat and the bottom plate to form a frame structure. An upper elastic member is arranged at the bottom center of the upper seat, and a lower elastic member is arranged at the upper center of the bottom plate. An upper top block facing the upper elastic member is arranged above the upper seat, and a lower top block facing the lower elastic member is arranged below the bottom plate. After adopting the above structure, on the one hand, the structure of the column itself makes the weight very light, and the material waste is avoided during the processing, saving costs. On the other hand, the base and the column are arranged separately, which makes the installation easy and convenient while reducing the overall volume, further reducing the manufacturing cost. In addition, the limit block arranged on the upper part of the bottom plate makes the bottom plate very thin while ensuring the installation position, further reducing the overall weight.

[0004] The patent document with announcement number CN115807832A discloses an elastic support structure of a wind turbine generator set, which relates to the technical field of wind turbine generators. The structure comprises a wind turbine gearbox body, a vibration reduction base is attached to the lower end of the wind turbine gearbox body, a mounting seat is arranged on the surface of the vibration reduction base, a support assembly is arranged at the lower end of the vibration reduction base, the support assembly is symmetrically structured with a spring steel plate 1 as the center, the two ends of the support steel column are respectively fixedly connected to the vibration reduction base and the surface of the buffer block, a mounting hole is opened through the side wall of the mounting seat, the vibration absorber is fixedly installed inside the mounting hole and fixedly connected to the buffer block, the buffer spring is fixedly installed and arranged on the outside of the vibration absorber, the two buffer blocks are fixedly installed with a spring steel plate 1 and a spring steel plate 2, a T-shaped slot is recessed inside the mounting seat, the T-shaped block is slidably installed inside the T-shaped slot and fixedly installed at the lower end of the buffer block, which effectively improves the buffering effect of the device on the wind turbine gearbox body, thereby improving the service life and stability of the wind turbine generator set.
