A New Type of Surface Bearing Type Gearbox Shock Absorber

Abstract

The invention proposes a novel surface bearing type gearbox shock absorber, which is a semi-circular tile type structure, and is sequentially composed of an outer clapboard, an outer rubber layer, a middle clapboard, an inner rubber layer and an inner clapboard from the outside to the inside; The length of the connection between the outer rubber layer and the outer partition is less than the length of the connection between the outer rubber layer and the middle partition, and the length of the inner rubber layer and the middle partition is shorter than the length of the inner rubber layer and the inner partition. The length of the board connection, the length of the rubber layer and the adjacent two layers of the separator have a length difference, and the outer length of each rubber layer is smaller than the inner length; the length of the rubber layer and the adjacent two layers of separators are connected. The difference gradually decreases along the arc from the middle area to the 45° area and then to the areas on both sides; the centers of the outer baffle, the middle baffle and the inner baffle are on a line, but not at a point, with an eccentric amount . The novel surface bearing type gearbox shock absorber of the invention is mainly applied to the buffering and vibration reduction of the double-fed wind power generator, and can obviously prolong the service life of the shock absorber.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a novel surface bearing type gearbox shock absorber. Background technique [0002] Wind energy is a clean and sustainable energy. Compared with traditional energy, wind power does not depend on external energy; wind power has gradually become an important part of many countries' sustainable development strategies and is developing rapidly. With the development trend of large-scale and offshore wind power market in the international market, megawatt-level high-power wind turbines will become the mainstream. Most fans are doubly-fed and semi-direct-drive units, and stability is very important during operation. [0003] With the continuous improvement of the supporting infrastructure of low wind speed wind farms, the application of low wind speed large blade wind turbines has developed rapidly. Major domestic manufacturers of complete machines have launched their own new m...
