[0002] The wind turbine generator system needs the support mechanism to support the gear box when using, and the existing hydraulic gear box elastic support is combined with natural rubber and steel plate production, and the structure is more, the weight is bigger, the mould is more complex, and the installation is inconvenient, the transportation and maintenance are inconvenient, and the manpower and material resources are consumed, so the long processing use demand of people cannot be met.

[0003] In view of the above situation, it is necessary to improve the existing wind turbine generator support structure, so that it can adapt to the needs of wind turbine generator support use. UTILITY MODEL CONTENT

[0004] In order to solve the above technical problems, the utility model provides a new type hydraulic polyurethane elastic support for wind turbine generator system, which comprises a mounting plate, a rubber cavity arranged on the mounting plate, and a polyurethane elastomer arranged on the mounting plate and located outside the rubber cavity, the rubber cavity is installed on the mounting plate, and the polyurethane elastomer is clamped with the rubber cavity.

[0005] Further supplement to the technical scheme, the mounting plate is provided with a rubber cavity fixing plate above, the rubber cavity is fixedly installed on the rubber cavity fixing plate, and a plurality of mounting holes are arranged in the circumferential direction of the rubber cavity fixing plate for connecting and fixing the mounting plate with bolts.

[0006] Further supplement to the technical scheme, a plurality of protrusions are arranged in the circumferential direction of the rubber cavity, and a plurality of limiting grooves are arranged in the circumferential direction of the polyurethane elastomer, which are one-to-one corresponding with the protrusions.

[0007] Further supplement to the technical scheme, the protrusions are square, and the limiting grooves are matched with the protrusions to facilitate the installation of the protrusions in the limiting grooves.

[0008] Further supplement to the technical scheme, the polyurethane elastomer is further provided with a receiving groove below for receiving the rubber cavity fixing plate.

[0009] Further supplement to the technical scheme, the diameter of the receiving groove is greater than that of the rubber cavity fixing plate, so that the rubber cavity fixing plate can be accommodated in the polyurethane elastomer when covering.

[0010] The beneficial effects of the present application are that the polyurethane elastic support is integrally formed, the structure is simple, the weight is greatly reduced, and the whole is designed in a plurality of parts, the single piece weight is smaller, the product consistency is good, the transportation is convenient, the installation and disassembly are convenient, and the applicability is stronger.

[0015] In order to facilitate the person skilled in the art to the technical scheme of the present technology more clearly, the following will be combined with the attached Figure 1 -3 detailed description of the technical scheme of the utility model:

[0016] A new type of hydraulic polyurethane elastic support for wind turbine, including mounting plate 1, set up on mounting plate 1 rubber cavity 2, set up on mounting plate 1 and located rubber cavity 2 outside polyurethane elastomer 3, rubber cavity 2 is installed on mounting plate 1, polyurethane elastomer 3 and rubber cavity 2 are engaged;Polyurethane elastomer 3 is the elastic support core component, supports the gear box of wind turbine, shock absorption and noise reduction;Mounting plate 1: elastic support bottom plate, fixed rubber cavity 2, complete injection pressure maintaining work;Rubber cavity 2 injection, increase the rigidity of elastic support, meet the rigidity demand;Among them, polyurethane elastomer 3 is provided with mounting recess 9 for installing rubber cavity 2, and the outer surface of rubber cavity 2 is semispherical.

[0017] Among them, mounting plate 1 is provided with rubber cavity fixed plate 4, for fixing rubber cavity 2, limiting the radial movement of elastic support, wherein rubber cavity 2 is fixedly installed on rubber cavity fixed plate 4, and a plurality of mounting holes 5 are arranged in the circumferential direction of rubber cavity fixed plate 4 for connecting and fixing the mounting plate 1 by bolts.

[0018] Among them, rubber cavity 2 is provided with a plurality of protrusions 6 in the circumferential direction, and a plurality of limiting recesses 7 are arranged in the circumferential direction of polyurethane elastomer 3 and correspond to the protrusions 6;By the cooperation of the two, the radial movement of the elastic body is limited, and the product replacement is more convenient;Further, the protrusions 6 are square, and the limiting recesses 7 are matched with the protrusions 6 to facilitate the installation of the protrusions 6 in the limiting recesses 7;The radial movement of the elastic support can be well limited, the axial movement of the elastic support is limited by the outer frame 10, and the installation and operation requirements of the elastic support are met.

[0019] The polyurethane elastomer 3 is further provided with a receiving groove 8 below for receiving the rubber cavity 2 fixing plate.
