    摘要: A bearing retainer (1) having a body (1a) formed of steel has a nitride layer (N) on the body surface. The average particle diameter of a nitride contained in the nitride layer (N) is not more than 1 µm. The surface of the retainer (1) is subjected to fluoriding treatment, and is then subjected to nitriding treatment. The above-mentioned oxide is removed by replacing an oxide on the surface of the retainer (1) with a metal fluoride film by the fluoriding treatment. In the nitriding treatment, a gaseous mixture of gas for nitriding, for example, ammonia gas and hydrogen gas for removing the metal fluoride film is brought into contact with the surface of the retainer (1). A precise and uniform nitride layer (N) is obtained in a state where the oxide is reliably removed from the surface of the retainer (1).

    摘要: The present invention relates to a cage for a greased rolling element bearing, characterized in that the cage is coated with a solid lubricant containing coating for lowering the running temperature of the cage and/or the bearing.
    The solid lubricant coating preferably contains a disulphide or diselenide of a group V or VI transition metal, more preferably MoS₂ and/or WS₂. The solid lubricant can be present in combination with an organic resin, such as PTFE.
    The invention further relates to a method for lowering the running temperature of cages of rolling element bearings, improving the life of the grease present in said bearing and/or improving the service life of a rolling element bearing, characterized in that the bearing cage or roller ends is/are coated with solid lubricant coating.

    摘要: Le procédé utilisable, en particulier pour constituer la cage de roulement, permet de constituer des articles poreux imprègnés de lubrifiant. Suivant le procédé, on prépare un mélange de matière de base et de laine métallique constituée de fibres dont le diamètre moyen ne dépasse pas 0,1 mm, le rapport des teneurs en volume de matière et de fibres étant compris entre 100/30 et 100/200 et ladite matière étant de nature telle qu'elle permet de constituer une ébauche solide à faible coefficient de frottement et faible fragilité par moulage, injection, extrusion ou pultrusion ; on constitue ladite ébauche ; on usine ladite ébauche à la forme finale ; on élimine la laine métallique par attaque chimique pour créer une porosité ouverte ; et on imprègne les pores par un lubrifiant.

    摘要: Cages of large bearings are normally made of plate-steel or brass. Due to relativelly high speed excessive wear, noise and surface defects develop between the cage (7) and rolling bodies (1). The claimed design obviates these known disadvantages by covering the contact area (11) between cage-pockets and rolling bodies with a rubber layer (13) whereby the thickness of the layer should preferably be in order of 0.5-0.05 times the cage material thickness. This makes it possible to take up large forces between rolling bodies and the cage without crushing the rubber layer. The lubri­cant film thickness will be 10 to 100 times larger than in a steel or plastic cage and therefore an optimum hydro-dynamic lubrication obtained. Besides high degree in manufacturing the cage or rubber layers is not required as long as the errors in form and surface roughness can be taken up by elastic deformation of the rubber layer (13). Further the oil film thickness will be less sensitive to local loads and pressures.
