Abstract
The utility model discloses a shock absorption device of a wind generator, which is arranged between a generator and a frame and comprises a damping disc, a plurality of upper rubber parts, a plurality of lower rubber parts, rigging screws and nuts. The middle part of the damping disc is upwards connected with a generator assembly. The rim of the damping disc is provided with the plurality of assembly holes. Each upper rubber part is provided with a nested hole. Each lower rubber part is provided with a gasket portion, a nested portion and one assembly hole which penetrate through the gasket portion and the nested portion. The gasket portions are arranged between the damping disc and a connecting cover of the frame. The nested portions penetrate through the assembly holes and are inserted into the nested holes of the upper rubber parts. The upper rubber parts, the damping disc and the lower rubber parts are tightly fixed on the connecting cover of the frame through the rigging screws and the nuts. The upper rubber parts and the lower rubber parts are correspondingly arranged at the upper side of the damping disc and the lower side of the damping disc. The shock absorption disc of the wind generator can effectively buffer the mechanical shock between the generator and the frame, reduces mechanism damage to the wind generator, and lowers the noise simultaneously.
Description
Technical field
The utility model belongs to technical field of wind power generation, is specifically related to the damping device of wind-driven generator.
Background technique
The gas springing that produces between blade of wind-driven generator and the pylon is moving to be that wind-driven generator is intrinsic, can't eliminate theoretically.This transfer of vibration all is very harmful to housing construction, blade and inner body, must try every possible means to absorb or reduce this natural vibration, could effectively improve the working life and the Safety performance of unit.
Summary of the invention
The utility model purpose provides a kind of wind-driven generator damping device, can reduce mechanical shock, makes wind-driven generator reduce noise as far as possible and prolongs generator working life.
Above-mentioned purpose is achieved through the following technical solutions: a kind of wind-driven generator damping device is connected between generator and the pylon; It is characterized in that, comprising: damping disc, its middle part upwards connects generator assembly, and some pilot holes are offered at the edge; Some rubber parts of going up, rubber parts has nested hole on each; Some rubber parts down, rubber parts has gasket part, nesting part and runs through nesting part and the pilot hole of gasket part under each, and pad site is between damping disc and pylon connecting cover, and nesting part passes in the nested hole of rubber parts in pilot hole, the embedding; Rigging screw and nut will be gone up rubber parts, damping disc, descend rubber parts to be fixed tightly on the pylon connecting cover, and corresponding upper and lower rubber parts is positioned at damping disc both sides up and down.
Above-mentioned wind-driven generator damping device also comprises the vibration damper cover, is located at the periphery of the assembly of rubber parts, damping disc, following rubber parts, pylon connecting cover, rigging screw and nut formation.Described vibration damper cover is three lobe composite structures, and each lobe is fixedlyed connected with the damping disc lateral margin by screw.
The end face of described rigging screw cap and the end face of nut all are provided with pad.
The utility model by be provided with in decompression dish both sides correspondence some on rubber parts and following rubber parts, and make that rubber parts is fitted to each other up and down, effectively the mechanical shock between buffer dynamo and pylon reduces wind-driven generator is produced mechanical deterioration, reduces noise simultaneously.The vibration damper cover that is provided with can play protection dampening assembly and effect attractive in appearance, and can further reduce noise.
