(FR) DISPOSITIF DE RETENUE DE ROULEMENT À BILLES ET ROULEMENT À BILLES
(JA) 玉軸受用保持器及び玉軸受
Abstract:
(EN) Provided is a land riding ball bearing retainer (14) that is guided by at least one of inner and outer bearing rings (11, 12), the ball bearing retainer (14) being characterized by comprising an annular part having a circular shape and facing the bearing rings (11, 12), and being characterized in that a plurality of projections (22) that can contact the bearing rings (11, 12) via lubricant are formed on the guide surface of the annular part in the circumferential direction viewed from the axial direction.
(FR) L'invention concerne un dispositif de retenue de roulement à billes tout terrain (14) qui est guidé par au moins l'une des bagues de roulement intérieure et extérieure (11, 12), le dispositif de retenue de roulement à billes (14) étant caractérisé en ce qu'il comprend une partie annulaire ayant une forme circulaire et faisant face aux bagues de roulement (11, 12), et étant caractérisé en ce qu'une pluralité de saillies (22) qui peuvent entrer en contact avec les bagues de roulement (11, 12) par l'intermédiaire d'un lubrifiant soient formées sur la surface de guidage de la partie annulaire dans la direction circonférentielle vue depuis la direction axiale.
(JA) 内外軌道輪(11、12)のいずれか一方によって案内される軌道輪案内形式の玉軸受用保持器(14)であって、軌道輪(11、12)と対向する環状の円環部を有し、円環部の案内面には、軌動輪(11、12)と潤滑油を介して接触可能な突起部(22)が、軸方向から見て周方向に複数形成されていることを特徴とする玉軸受用保持器(14)を構成する。
