Two-way damping hydraulic support type wind power gearbox installation device

Abstract

The invention discloses a bidirectional damping hydraulic support type wind power gear box mounting device with an aim to damp vibration of the wind power gear box within a low-frequency area and vibration in a medium- and high-frequency area and improve isolation effect. The bidirectional damping hydraulic support type wind power gear box mounting device comprises a bottom frame, a mounting frame and a top frame sequentially from bottom to top, the top frame comprises a first top plate and a second top plate, the first top plate and the second top plate are arranged on the two opposite sides of the mounting frame and connected with the bottom frame respectively via vertical connecting plates; a plurality of lower damping components are arranged between the bottom frame and the mounting frame, and a plurality of upper damping components are arranged between the first top plate and the second top plate as well as the mounting frame respectively.

Description

technical field [0001] The invention relates to a wind power gearbox vibration damping installation device, in particular to a two-way vibration damping hydraulic support type wind power gear box installation device. Background technique [0002] The wind power gearbox is an important mechanical component in the wind power generating set. Its main function is to transmit the power generated by the wind wheel under the action of the wind to the generator and make it obtain a corresponding speed. As a component that transmits power, the wind power gearbox bears both dynamic and static loads during operation, causing the wind power gearbox to generate complex vibration and noise, which will affect the service life and reliability of the entire wind turbine, so it is necessary to use A certain device controls the vibration and noise of the wind power gearbox within the specified range. [0003] The damping elements used to support wind power gearboxes in traditional technology ...

Problems solved by technology

The hydraulic mount produces a large energy loss along the way when the liquid flows between different chambers, so that the vibration energy can be dissipated as soon as possible to achieve the purpose of damping vibration; but the current structure of the hydraulic mount is not suitable for the low frequency region Vibration can effectively reduce vibration and shock isolation, but for the vibration in the medium and high frequency region, due to the large inertia of the liquid in the flow channel between the chambers, the liquid hardly has time to flow, and it cannot be effectively used by the liquid flow. Vibration energy consumption, so it is not good for vibration isolation in the middle and high frequency areas
