Abstract
(EN)
A roller bearing formed by interposing spacers between rollers which enables the smooth flow of a lubricant near the rolling surfaces thereof to reduce the agitating resistance of the lubricant by the spacers so that a higher allowable rotating speed can be attained. The roller bearing comprises the plurality of rollers (16) rollably interposed between the inner ring raceway surfaces and the outer ring raceway surfaces thereof and the spacers (18) between the adjacent rollers (16). Each of the spacers (18) comprises extension parts (18a) facing the end faces (16b) of the roller at both ends in the axial direction.

La présente invention concerne un palier à rouleaux formé en interposant des entretoises entre des rouleaux qui permet l’écoulement sans heurts d’un lubrifiant près de surfaces de roulement de celui-ci pour réduire la résistance à l’agitation du lubrifiant par les entretoises de sorte qu’une vitesse de rotation plus élevée admissible puisse être atteinte. Le palier à rouleaux comprend la pluralité de rouleaux (16) interposés de façon à rouler entre les surfaces de chemin de roulement de la bague intérieure et les surfaces de chemin de roulement de la bague extérieure de celui-ci et les entretoises (18) entre les rouleaux adjacents (16). Chacune des entretoises (18) comprend des parties de prolongement (18a) tournées vers les faces d’extrémité (16b) du rouleau au niveau des deux extrémités dans la direction axiale.
