Problems solved by technology

However, no matter whether a single top foil corresponds to multiple bottom foils or multiple top foils correspond to multiple bottom foils, the improvement of the technical solution will bring about a further increase in the complexity of the bearing structure, and the top foil and the bottom foil need to be handled separately during engineering implementation. The final fixed installation to the surface of the bearing seat greatly increases the complexity of the process and the difficulty of assembly, which limits its large-scale application in the civil field

Abstract

The invention relates to a cantilever structure elastic foil dynamic pressure air floatation thrust bearing comprising a thrust bearing seat and a plurality of cantilever structure elastic foils installed on the thrust bearing seat. Each cantilever structure elastic foil comprises a top foil part, a bending part and a bottom foil part which are connected in sequence, and each bottom foil part is provided with a plurality of elastic units with the same height. The plurality of cantilever structure elastic foils are sequentially connected end to end, and the top foil part of each previous cantilever structure elastic foil is lapped on the elastic units of the bottom foil part of the corresponding next adjacent cantilever structure elastic foil. The air floatation thrust bearing comprises an elastic supporting unit in a bump foil bearing, has the advantages of a simple structure of a cantilever bearing, can adapt to different loads and use environments, and can meet the use requirements of high operation stability and large-scale engineering application.

Description

technical field [0001] The invention relates to the technical field of foil dynamic pressure gas bearings, in particular to an elastic foil dynamic pressure air bearing with a cantilever structure. Background technique [0002] The dynamic pressure air bearing uses the dynamic pressure effect of the gas working fluid between the friction surfaces of the bearing to lubricate and cool, and is divided into rigid surface bearings and flexible surface bearings. Compared with the rigid surface dynamic pressure gas bearing with herringbone groove or spiral groove surface, it cannot be adjusted adaptively after its nominal clearance is determined, while the biggest feature of the foil dynamic pressure gas bearing is its flexibility, which can ensure the bearing surface and support structure Deformation occurs under the effect of gas dynamic pressure, which causes changes in the gas film gap. The change of the air film gap will in turn affect the pressure distribution of the bearing...
