Abstract

The authors had analyzed the externally pressurized porous thrust gas-bearing in the preveous paper(2). 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 'frange', around the porous part. They applied the preveous theory to this case and obtained the theoretical pressure distribution and load capacity. The experimental results coincided well with theoretical one qualitatively and fairly well quantitatively.
