Research of Externally Pressurized Porous Thrust Gas-Bearing : With Flat and Solid Ring Surface

Abstract

The authors analyzed an externally pressurized porous thrust gas-bearing in the previous paper. In such type of bearings, their characteristics are much affected by the roughness of porous surface of bearings. In this paper, to avoid such effect and to improve the bearing performance, the authors investigated the porous thrust gas-bearing with flat and solid ring surface, so-called 'flange', around the porous part. They applied the previous theory to this case and obtained the theoretical pressure distribution and load capacity. The experimental results coincided well with the theoretical ones qualitatively and fairly well quantitatively.
