Abstract
This invention is a bearing tube for a marine propeller shaft, and a method of making such a tube according to which polyacrylonitrile or other fibres (8) carrying a sticky resin (7) are wound onto a mandrel (5) and, at least at the bearing lining, wear resistant powder (6) or other compound is included with the fibres and resin to improve the properties of the bearing lining. Such a bearing tube including essentially a resin impregnated polyacrylonitrile fibres and the wear resistant compound can be easily machined to size without any health hazards, and can be lubricated by oil or water (even sea water) and is dimensionally stable.
Claims8
A method of forming a bearing tube from a plurality of polyacrylonitrile fibres, a sticky resin, and a wear resistant compound and using a forming mandrel, which comprises:
- treating said plurality of fibres with said sticky resin;
- winding said plurality of resin-treated fibres onto said mandrel so as to form an inner and an outer surface of said bearing tube;
- applying said wear resistant compound to said fibres immediately subsequent to said step of winding said fibres;
- and
- solidifying said sticky resin.
