Problems solved by technology

[0003] The elastic body in the rubber spring shock absorber of the prior art generally adopts a pure conical structure, and the angle formed by the conical elastic body and the longitudinal axis of the shock absorber is generally greater than 30°, but it is limited by the volume of the shock absorber , the deformation of the conical elastic body is not large, so the vibration damping effect is also more limited

Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] exist figure 1 A specific embodiment of the shock absorber for connecting the wind motor and the frame of the present invention is shown in . In this embodiment, the shock absorber mainly includes a base 1 connected to the frame, an upper damping elastic body 2 and a lower damping elastic body 4 arranged in the base 1, and an upper damping elastic body 2 acting on the The upper core 3 and the lower core 5 acting on the lower damping elastic body 4. The upper core 3 and the lower core 5 are connected via a connecting piece 6 . Moreover, both the upper core 3 and the lower core 5 have no axial movement relative to the connecting piece 6 .

[0022] In one embodiment, an upper accommodating chamber and a lower accommodating chamber are provided in the base 1 . The upper accommodating cavity and the lower accommodating cavity are both col...

Abstract

The invention discloses a shock absorber for connecting a wind motor with a frame. The shock absorber comprises a base, an upper core, a lower core, an upper shock absorption elastomer and a lower shock absorption elastomer, the base is connected with the frame, an upper containing cavity and a lower containing cavity are formed in the base, both the upper core and the lower core are of a structure formed by connecting a column with a cone, the upper core is connected with the lower core through a connector, and the upper shock absorption elastomer and the lower shock absorption elastomer are arranged in the base and matched with the upper core and the lower core respectively and generate elastic deformation perpendicular to the columns and the cones of the upper core and the lower core under the squeezing action of the upper core and the lower core. The shock absorber can achieve better shock absorption effects.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a shock absorber for connecting a wind power motor and a frame. Background technique [0002] With the rapid development of installed capacity of wind power all over the world and the maturity and continuous improvement of wind power generator technology, wind power has increasingly become one of the energy sources that countries in the world pay more attention to and focus on development. The use of wind power can provide people with clean energy, but the vibration and noise caused by the vibration of the generator set cannot be ignored. Noise is produced partly by mechanical movement and partly by aerodynamics. Among them, the mechanical noise is mainly generated by the rotating machinery (especially the gearbox and generator) in the engine room. In order to reduce the noise transmitted from the gearbox and the generator to the frame and tower when the wind turb...
