Problems solved by technology

However, the inner cavity pressure of ordinary hydraulic supports cannot achieve the purpose of increasing the stiffness. Therefore, there is an urgent need for an elastic element that can not only achieve the maximum stiffness required during work, but also increase the stiffness adjustment range of the hydraulic support.

Embodiment Construction

[0024] The present invention is introduced below by accompanying drawing.

[0025] figure 1 The structure of a liquid composite spring 100 for a gearbox hydraulic support device according to the present invention is shown. Such as figure 1 As shown, the liquid composite spring 100 includes a compressible rubber body 111 having a cylindrical structure, and one end surface (eg, the lower end surface) of the rubber body 111 is provided with a cavity 113 , and the cavity 113 is filled with liquid.

[0026] Such as figure 1 As shown, a pressure elastic membrane 130 is provided in the liquid containing cavity 113 of the rubber body 111 . The outer shape of the pressure elastic film 130 is adapted to the structure of the cavity 113 , so that the outer surface of the pressure elastic film 130 is in close contact with the inner wall of the cavity 113 . A radially outwardly protruding lip portion 131 is provided at an end portion of the pressure elastic membrane 130 . The lip porti...

Abstract

The invention provides a liquid compound spring for a gearbox hydraulic supporting device. The liquid compound spring comprises a sealing valve base, a spring body arranged on the sealing valve base and a reinforcing part. A liquid containing cavity is defined by the spring body and the sealing valve base. A pressure elastic film is installed in the liquid containing cavity. The reinforcing part is arranged in the body part and configured to be a continuous metal framework.

Description

technical field [0001] The invention relates to the field of damping systems for gearboxes of wind power generating sets, in particular to a liquid composite spring used for a hydraulic support device of a gearbox. Background technique [0002] In recent years, people are actively developing clean energy, among which wind energy is a clean and sustainable new energy. With the continuous development of wind energy, wind power generation technology has developed rapidly. With the continuous development of megawatt wind turbines, the load on the wind turbines is getting bigger and bigger. Therefore, the shock absorption of the key components of the generator set is also particularly important. [0003] The support method of the wind power generating set in the prior art mainly adopts hydraulic support. The hydraulic support is mainly used for four-point support models, and is a new type of shock-absorbing support developed on the basis of traditional elastic supports. The s...
