Abstract

La présente invention concerne un palier multiple qui comporte une pluralité de paliers reliés les uns aux autres de telle sorte que, même en cas d'endommagement d'une partie de palier sur un côté, la période entre les remplacements ou les réparations de palier puisse être étendue. Le palier multiple comprend : une première partie de palier ; une deuxième partie de palier disposée en alignement avec la première partie de palier ; une roue externe disposée dans un sens radial externe par rapport à la première partie de palier ; une roue interne disposée dans un sens radial interne par rapport à la deuxième partie de palier ; et une roue de liaison agencée d'un seul tenant avec l'intérieur de la première partie de palier et l'extérieur de la deuxième partie de palier. Dans le palier multiple de la présente invention, une pluralité de paliers sont reliés entre eux, et une roue interne et une roue externe sont formées d'un seul tenant entre un palier et le suivant. De cette manière, la rotation est communiquée à chaque palier, et même en cas d'endommagement d'une partie des paliers, la rotation est toujours possible grâce aux paliers non endommagés. Ceci permet d'étendre la période entre les remplacements et les réparations de palier.
