TAPERED ROLLER BEARING

摘要

A tapered roller bearing includes: an outer ring; an inner ring; a plurality of tapered rollers; and a cage that holds the tapered rollers at equal intervals in the circumferential direction of the tapered roller bearing. A small-diameter-side inner periphery end portion of the cage is located at a position inward of an axially outer small end face of the inner ring in the axial direction of the tapered roller bearing. A small-diameter-side end face of the cage has an inwardly tilted face that is tilted inward in the axial direction from the inner periphery end portion from the radially inner side to the radially outer side.

1. A tapered roller bearing comprising:
an outer ring having a tapered outer raceway surface formed on an inner peripheral face of the outer ring; an inner ring having a tapered inner raceway surface formed on an outer peripheral face of the inner ring; a plurality of tapered rollers rollably disposed between the outer raceway surface and the inner raceway surface; and a cage that holds the tapered rollers at equal intervals in a circumferential direction of the tapered roller bearing, wherein a small-diameter-side inner periphery end portion of the cage is located at a position inward of an axially outer end face of the inner ring in an axial direction of the tapered roller bearing, and a small-diameter-side end face of the cage has an inwardly tilted face that is tilted inward in the axial direction from the inner periphery end portion from a radially inner side to a radially outer side.
