Abstract

The invention discloses a novel tilting pad radial gas bearing which comprises a bearing body, an elastic tilting surface supporting structure and a top foil, wherein the elastic tilting surface supporting structure consists of metal rubber blocks and an elastic foil and is arranged on the tilting surface of the bearing body; the top foil covers the metal rubber blocks and the elastic foil; the pad of the bearing body and a bearing housing are of an integral structure; the pad of the bearing body is connected with the bearing housing by virtue of a flexible beam; and grooves are formed in two ends of the pad. A wave-shaped bulge is formed on the elastic foil, and a rectangular strip-shaped foil is reserved in one end of the bulge; the elastic foil is arranged in the middle of the pad of the bearing body; one end of the reserved rectangular strip-shaped foil is fixed on the tilting surface, and the other end of the reserved rectangular strip-shaped foil is freely arranged; and the metal rubber blocks are arranged in the grooves in two ends of the pad. The tilting pad radial gas bearing provided by the invention has the characteristics of high bearing capacity, high rigidity, high damping property and high stability.

Description

technical field [0001] The invention relates to the technical field of air bearings, in particular to a novel tilting pad radial gas bearing. Background technique [0002] The one-piece tilting pad radial gas bearing is an adaptive semi-flexible support gas dynamic pressure bearing. The pad and the bearing sleeve in the bearing are integrated, and the pad and the bearing sleeve are connected through flexible beams. Compared with ordinary rotor bearings, it has a series of advantages such as oil-free lubrication, small friction loss, high speed, and can work in extreme temperature environments. Compared with traditional rigid gas bearings, its stability has been greatly improved. At the same time, compared with the traditional tilting pad gas bearing, its one-piece structure eliminates the wear of the pad and the fulcrum, eliminates the installation error of the pad, and simplifies the processing process of the bearing. The integrated tilting pad radial gas bearing has bro...
