Problems solved by technology

The adjustment amount of this adjustment method is very small, and it is difficult to compensate the deviation of the product installation height caused by the processing error of the frame and the performance fluctuation of the shock-absorbing support elastic body, which affects the reliability of the system. Due to the lack of adjustment mechanism, the product installation and It is inconvenient to disassemble
In addition, the rubber elastic body is exposed in the wind turbine nacelle, which is easily eroded by dust, sand and grease, etc., which has a great impact on the service life of the vibration damping support device, so it is necessary to further improve this

Abstract

The invention relates to a damping support device with a height adjusting function and a rubber elastomer protecting function for a wind generating unit gearbox. The damping support device comprises a mounting seat, a height adjusting device and an elastic support piece, wherein the mounting seat comprises a seat body and an abutting cover, the seat body is provided with an accommodating cavity, the abutting cover is arranged at the opening of the accommodating cavity, a rubber elastomer is arranged in the accommodating cavity, the height adjusting device is used for adjusting the height, the lower end of the height adjusting device is accommodated into the accommodating cavity of the mounting seat, the upper end of the height adjusting device penetrates through a center hole of the abutting cover and extends out of the accommodating cavity, the elastic support piece is provided with a rubber layer, and the elastic support piece is arranged between the bottom of the height adjusting device and the seat body of the mounting seat. The damping support device has the advantages that the mounting height of a supported object can be freely adjusted, and the erosion on the rubber elastomer by environments is reduced.

Description

technical field [0001] The invention mainly relates to a vibration-damping support device for a gearbox of a wind power generating set. The vibration damping support in the present invention is mainly used in the buffering and vibration damping of the gearbox of the doubly-fed wind power generating set, and has the functions of height adjustment and protection of the rubber elastic body, and can also be applied to equipment such as rolling stock, ships, and construction machinery. vibration isolation system. Background technique [0002] Due to the rotation and swing of the blades of the wind turbine system, the hub will transmit a large force to the transmission components of the wind turbine, which will inevitably cause vibration and noise of each component. Therefore, the design of the damping and vibration reduction system of each component appears to be particularly important. In order to ensure the smooth operation of each component in the transmission system of the ...
