Embodiment 1

[0016] Depend on figure 1 It can be seen that the present invention is a vibration-damping support for the gearbox of a wind power generating set. A floating support method is adopted to place the outstretched arm of the gearbox of a wind power generating set in a "back"-shaped frame-type vibration-damping support seat and fix it on the Between the upper and lower elastic bodies in the "back"-shaped frame-type vibration-damping support seat, the upper and lower arms of the gear box of the wind power generating set are in a floating elastic support state between the upper vibration-damping elastic body and the lower vibration-damping elastic body.

[0017] It can be seen from Fig. 2-3 that what the present invention proposes is a vibration-damping support device for a wind turbine gearbox. A vibration-damping support 1 is installed on both sides of the gearbox 2, and the vibration-damping support 1 passes through 8 double-headed The screw rod 14 is fixed on the main frame 3 , a...

Abstract

The invention relates to a wind power generator group gear box oscillation damping support method and an oscillation damping support device thereof. A floating support manner is used for putting the stretching arm of the wind power generator group gear box into a square hole-shaped frame typed oscillation damping support base, and the stretching arm is fixed between an upper elastic body and a lower elastic body of the frame typed oscillation damping support base, thus leading the stretching arm to be in floating and elastic support state between the two elastic bodies. And the oscillation damping support device comprises the oscillation damping support base and oscillation damping elastic bodies installed in the oscillation damping support base; the oscillation damping support base has the fame typed structure; the square hole-shaped frame is composed of a U-shaped frame and a beam; an upper oscillation damping elastic body and a lower oscillation damping elastic body are respectively arranged at the upper and the lower part inside the square hole-shaped frame. The stretching arm of the wind power generator group gear box is arranged between the upper oscillation damping elastic body and the lower oscillation damping elastic body, thus forming elastic floating support.

Description

technical field [0001] The present invention mainly relates to an installation method and device structure of components of a generator, in particular to a vibration-damping support method and device structure applied to a gearbox of a wind power generating set. The invention is mainly applied to the vibration-damping support of the gearbox of the wind power generating set, and can also be applied to the vibration-isolation system of locomotives, ships, engineering machinery and other equipment. Background technique [0002] The wind turbine system is mainly a 3-point support method. Due to the rotation and swing of the blades, the hub will transmit a large force to each transmission part of the wind turbine, which will inevitably cause vibration and noise of each component. Therefore, each The design of component damping and vibration reduction system is particularly important. In order to ensure the smooth operation of each component in the transmission system of the wind...
