Abstract

The present invention provides a tapered roller bearing. In the tapered roller bearing, the large flange portion is provided at the end portion on the axial side of the inner ring and protrudes radially outward. The lubricating oil retaining member is provided integrally with the outer ring, and is disposed at a position overlapping the large flange portion when viewed in the radial direction. The lubricating oil retaining member includes: a cylindrical portion extending in the axial direction and located at an end portion on one axial side of the outer ring; and an annular portion extending radially inward from the axially one end portion of the cylindrical portion . The inclined surface is arranged on the outer peripheral surface of the end portion of the large flange portion on one side in the axial direction, and the distance from the rotation axis of the inner ring increases as it goes from one side in the axial direction to the other side. The end portion of the inclined surface is located between the annular portion and the end portion of the outer ring on one side in the axial direction in the axial direction.

Description

[0001] The disclosure of Japanese Patent Application No. 2016-249430 filed on December 22, 2016 including the specification, drawings, and abstract thereof is incorporated herein by reference in its entirety. technical field [0002] The present invention relates to a tapered roller bearing, and more specifically, to a tapered roller bearing in which lubricating oil is supplied to a space in which tapered rollers roll. Background technique [0003] A tapered roller bearing has an outer ring, an inner ring, a plurality of tapered rollers, and a cage. The tapered rollers are arranged such that their central axes are inclined with respect to the central axis of the tapered roller bearing. At least a part of the large-diameter end surface (hereinafter referred to as the large end surface) of the tapered roller is positioned radially outward of the bearing from the small-diameter end surface (hereinafter referred to as the small end surface). [0004] As a characteristic of the ...
