Title (EN) BEARINGS
(FR) PALIERS
Abstract:
(EN) 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 comprising 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.
(FR) Tube formant palier pour arbre d"helice de bateau et sa methode de fabrication selon laquelle des fibres de polyacrylonitrile ou d"autres fibres (8) impregnees d"une resine adhesive (7) sont enroulees autour d"un mandrin (5) et, au moins au niveau de la garniture, une poudre resistante a l"usure (6) ou un autre compose est ajoutee aux fibres et a la resine pour ameliorer les proprietes de la garniture du palier. Un tel tube formant palier comprend essentiellement des fibres de polyacrylo-nitrile impregnees de resine et le compose resistant a l"usure peut etre facilement usine aux cotes voulues sans risque pour la sante peut etre lubrifie a l"huile ou a l"eau (meme a l"eau de mer) et pre une excellente stabilite dimensionnelle.
