    • PROBLEM TO BE SOLVED: To provide an intermittent oil supply type rolling bearing device of a camshaft with a drive loss of an oil pump reduced by supplying a proper amount of lubricating oil to cam lobes. SOLUTION: A bearing housing 10 is formed with a central annular groove 10D and a housing oil hole 10E that passes through from the side surface of the groove to the outer surface. A cage 26 of a rolling bearing 20 has annular portions 26A on the both sides formed with a plurality of pockets containing rolling elements 28 so as to be rotatable, and a hollow shell-like connecting portion 26B connecting these annular portions 26A. The outer circumferential portion of the shell-like connecting portion 26B is formed in such a way to be inserted into the annular groove 10D of the bearing housing. A side surface 26D of the shell-like connecting portion is formed with a cage oil hole 26F passing through from a hollow portion 26E to the outer surface at a position with the same distance from the rotation center of the camshaft as the distance to the housing oil hole. The camshaft is provided with oil passages (30B, 30C) communicating to the hollow portion. COPYRIGHT: (C)2012,JPO&INPIT
    • 要解决的问题:提供一种凸轮轴的间歇供油型滚动轴承装置,其具有通过向凸轮凸角提供适量的润滑油而减少的油泵的驱动损失。解决方案:轴承壳体10形成有中心 环状槽10D和从槽的侧面通向外表面的壳体油孔10E。 滚动轴承20的保持架26在两侧形成有能够旋转的包含滚动体28的多个凹部的环状部26A和连接这些环状部26A的中空壳状连接部26B。 壳状连接部26B的外周部形成为插入轴承壳体的环状槽10D中。 壳状连接部的侧面26D形成有保持油孔26F,该保持油孔26F从与凸轮轴的旋转中心相距一定距离的位置从中空部26E向外表面延伸至与壳体 油孔。 凸轮轴设置有与中空部连通的油路(30B,30C)。
