Title (EN) NEEDLE ROLLER BEARING
(FR) PALIER A ROULEMENTS A AIGUILLES
(JA) 針状ころ軸受
Abstract:
(EN) A needle roller bearing has an outer ring having two outer ring members (12) split by a split line extending in the direction of the axis of the bearing, and also has needle rollers rollably placed on the raceway surface of the outer ring. The needle roller bearing satisfies the relationship of L/w < 0.5, where L is a non-contact length between the set of the outer ring members (12) and the set of the needle rollers (14) that pass on the butted sections between the two outer ring members, and w is an effective length of each needle roller (14).
(FR) L’invention concerne un palier à roulements à aiguilles comportant une bague extérieure présentant deux éléments de bague extérieurs (12) clivés par une ligne de clivage se prolongeant dans la direction de l’axe du palier, et des roulements à aiguilles (14) montés de façon à rouler sur la surface de roulement de la bague extérieure. Le palier à roulements à aiguilles vérifie la relation L/w < 0,5, où L est la longueur sans contact entre les deux éléments de bague extérieurs (12) et les roulements à aiguilles (14) passant sur les parties en butée entre les deux éléments de bague extérieurs, w est la longueur effective de chaque roulement à aiguilles (14).
(JA) 針状ころ軸受は、軸受の軸線方向に延びる分割線によって分割された2つの外輪部材12を有する外輪と、外輪の軌道面上に転動自在に配置される複数の針状ころとを備える。そして、2つの外輪部材の突合部上を通過する針状ころ14と外輪部材12との非接触長さLと、針状ころ14の有効長さwとは、L/w<0.5の関係を有する。
