Abstract:
A tapered roller bearing includes an inner ring including, on its outer circumferential surface, an inner raceway surface and including, on an end portion on a second axial side, a cone back face rib portion protruding radially outward, an outer ring including, on its inner circumferential surface, an outer raceway surface, a plurality of tapered rollers disposed between the inner ring and the outer ring, and an annular cage that retains the plurality of tapered rollers spaced from each other in a circumferential direction. The cage includes a small-diameter annular portion, a large-diameter annular portion located on the second axial side relative to the tapered rollers and the outer ring, and a plurality of cage bar portions. The large-diameter annular portion has an oil pocket having a first aperture that is open radially inward and a second aperture that is open toward the outer raceway surface.

Claim (Index 1):
A tapered roller bearing comprising:\n an inner ring including, on its outer circumferential surface, an inner raceway surface that expands in diameter from a first side in an axial direction toward a second side, which is opposite to the first side, in the axial direction and including, on an end portion on the second side in the axial direction of the inner ring, a cone back face rib portion protruding outward in a radial direction; an outer ring including, on its inner circumferential surface, an outer raceway surface that expands in diameter from the first side in the axial direction toward the second side in the axial direction; a plurality of tapered rollers disposed between the inner ring and the outer ring; and an annular cage that retains the plurality of tapered rollers such that the tapered rollers are spaced from each other in a circumferential direction, wherein the cage includes a small-diameter annular portion located on the first side relative to the tapered roller in the axial direction, a large-diameter annular portion located on the second side relative to the tapered roller and the outer ring in the axial direction, and a plurality of cage bar portions that connects the small-diameter annular portion and the large-diameter annular portion, spaces between each circumferentially-adjacent pair of cage bar portions in an area between the small-diameter annular portion and the large-diameter annular portion are cage pockets for accommodating the tapered rollers, and the large-diameter annular portion has an oil pocket having a first aperture that is open radially inward and a second aperture that is open toward the outer raceway surface.
