<p><P>PROBLEM TO BE SOLVED: To reduce torque loss due to the presence of a lubricating oil in a tapered roller bearing into which the lubricating oil flows. <P>SOLUTION: A through-hole for flowing the lubricating oil is formed through the axis of the tapered roller bearing 4. The lateral length L of the tapered surface 8a of the column part 8 of a cage 5 in slidable contact with the outer diameter surface of tapered rollers 4 is less than 11% of the averaged diameter D of the rollers. Since the amount of the lubricating oil remaining in the bearing is reduced, a torque loss due to the flow resistance of the lubricating oil is reduced. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
