Abstract
A gas bearing is formed of a bearing member of sintered material. Sintered grains of a layer forming a desired bearing surface are deformed into the shape of a honeycomb in non-cutting fashion and are subsequently finely worked in cutting fashion, so that super-fine pores formed at corners of the honeycomb arise and which form nozzles.
Claims14
A gas bearing, comprising:
- a bearing member having surface layers, bearing member and surface layers are built-up from sintered grains, at least one of said surface layers forming a bearig surface of said gas bearing;
- and
- the sintered grains of said at least one surface layer being shaped as honeycombs such that adjacent grains in the surface layer having greater contact with each other and that super-fine pores are provided a corners of the honeycombs.
A method for manufacturing a gas bearing having a bearing member of sintered grains so as to form at least one bearing surface on said bearing member having superfine pores, comprising the steps of:
- surface layers of said bearing member from sintered grains;
- and
- shaping the grains of at least one of said surface layers forming a bearing surface as honeycombs such that adjacent grains in the surface layer have greater contact with each other and that super-fine pores are provided at corners of the honeycombs.
A method of constructing a gas bearing of sintered grains and wherein a bearing surface is provided with pores therein, comprising steps of:
- providing a plurality of surface layers of sintered grains;
- and
- at least one surface layer the surface of which is to become a bearing surface being plastically deformed by rolling the sintered grains of the surface layer such that the adjacent grains become in greater intimate contact with one another, and wherein pores between the grains become smaller so as to form honeycombs with super-fine pores at corners of the honeycombs between adjacent grains.
