    • A rotatable member (40) such as a sprocket is rotatably mounted on a fixed shaft member (32), and a first oil passage (72) extending in a radial direction is formed by a thrust member (36) abutting an axial end surface of the rotating member. The inner end of the first oil passage communicates with a radial bearing interface (A) of the rotatable member, and an oil jet ejected from an orifice (68) of an oil nozzle (66) is directed to an open outer end of the first lubricating oil passage. Because the first oil passage is fixed in position, the radial bearing interface receives an adequate supply of lubricating oil fed from the oil nozzle. The other axial end of the rotating member may be provided with a second lubricating oil passage (82) which also extends in a radial direction, the second lubricating oil passage having an open outer end and an open inner end communicating with the radial bearing interface. The centrifugal force acting on the lubricating oil in the second lubricating oil passage promotes a favorable re-circulation of the lubricating oil, and hence a favorable lubrication.
    • 诸如链轮的可旋转构件(40)可旋转地安装在固定轴构件(32)上,并且径向延伸的第一油通道(72)由抵抗构件(36)的推力构件形成,该推力构件 旋转构件。 第一油路的内端与可旋转构件的径向轴承接口(A)连通,从油嘴(66)的孔口(68)喷出的喷油指向第一油路的开口外端 润滑油通道。 由于第一油路固定就位,径向轴承接口从油嘴供应足够的润滑油。 旋转构件的另一个轴向端可以设置有也沿径向延伸的第二润滑油通道(82),第二润滑油通道具有敞开的外端和与径向支承界面连通的敞开的内端。 作用于第二润滑油通路中的润滑油的离心力促进润滑油的良好的再循环,因此有利的润滑。
