Title (EN) ROLLING BEARING
(FR) PALIER À ROULEMENT
(JA) 転がり軸受
Abstract:
(EN) A rolling bearing is provided with: an inner ring (12) and an outer ring (14), which rotate relative to each other; rolling bodies (15) disposed between the inner ring (12) and the outer ring (14); and a retainer (16) provided between the inner ring (12) and the outer ring (14) and retaining the rolling bodies (15) at equal intervals in the circumferential direction. Flanges (20, 21) extending in the radial direction are provided on the inner-diameter side and outer diameter side of the axial ends of the retainer (16). Grooves (30, 31) which form labyrinths (24, 25) together with the flanges (20, 21) are provided at portions of both the inner ring (12) and the outer ring (14), the portions corresponding to the flanges (20, 21). The inner surfaces (34, 35) of the flanges (20, 21) and the axial end surfaces (38, 39) of the grooves (30, 31), the axial end surfaces (38, 39) facing the inner surfaces (34, 35) of the flanges, are tilted relative to the radial direction so as to generate the flow of a lubricating agent.
(FR) L'invention porte sur un palier à roulement qui comprend : une bague intérieure (12) et une bague extérieure (14), qui tournent l'une par rapport à l'autre ; des corps de roulement (15) disposés entre la bague intérieure (12) et la bague extérieure (14) ; et un organe de retenue (16) placé entre la bague intérieure (12) et la bague extérieure (14) et qui maintient les corps de roulement (15) à intervalles réguliers dans la direction circonférentielle. Des joues (20, 21) s'étendant dans la direction radiale sont formées sur le côté de diamètre intérieur et sur le côté de diamètre extérieur des extrémités axiales de l'organe de retenue (16). Des gorges (30, 31), qui forment des labyrinthes (24, 25) en combinaison avec les joues (20, 21), sont formées dans des parties de la bague intérieure (12) et de la bague extérieure (14), les parties correspondant aux joues (20, 21). Les surfaces intérieures (34, 35) des joues (20, 21) et les surfaces d'extrémité axiale (38, 39) des gorges (30, 31), les surfaces d'extrémité axiale (38, 39) faisant face aux surfaces intérieures (34, 35) des joues, sont inclinées par rapport à la direction radiale de façon à générer l'écoulement d'un agent lubrifiant.
(JA)  互いに相対回転する内輪12および外輪14と、内輪12と外輪14との間に介在する複数の転動体15と、内輪12と外輪14との間に配され、転動体15を円周方向等間隔に保持する保持器16とを備えた転がり軸受であって、保持器16の軸方向端部の内径側および外径側に、径方向に延びる鍔部20,21を設けると共に、内輪12および外輪14の鍔部20,21と対応する部位に、鍔部20,21とでラビリンス24,25が形成される凹溝30,31を設け、鍔部20,21の内側面34,35および凹溝30,31の鍔部内側面34,35と対向する軸方向端面38,39を、潤滑剤の流れを発生させるように径方向に対して傾斜させる。
