Abstract

Palier à roulement permettant une utilisation dans des conditions extrêmes sans risque de déformation à la fabrication, ni de soudage des partenaires de roulement. Les paliers comportent des billes, rouleaux, rouleaux coniques ou aiguilles réalisés en alliage dur revêtu d'une matière dure résistant à l'usure et présentant un faible coefficient de frottement vis-à-vis du matériau de la bague, dont le rôle est d'assurer une barrière de diffusion, les materiaux de revêtement consistant en particulier en carbures et/ou nitrures et/ou carbonitrures et/ou borures et/ou siliciures et/ou oxydes des éléments des groupes III à VI de la classification périodique, sous forme de mélanges d'éléments ou de cristaux mixtes. Variantes de réalisation. L'invention peut être utilisée à la constitution de paliers pour conditions extrêmes telles que paliers pour usages spatiaux, réacteurs, etc.
