TAPERED ROLLER BEARING AND MANUFACTURING METHOD FOR TAPERED ROLLER BEARING

In a tapered roller bearing, neighboring pillar parts constitute a first engagement allowance in which an inner diameter-side opening width of each of the pockets becomes smaller than a roller diameter at a position of the opening width in a direction of a rotation axis of each of the tapered roller...

Zusammenfassung:	In a tapered roller bearing, neighboring pillar parts constitute a first engagement allowance in which an inner diameter-side opening width of each of the pockets becomes smaller than a roller diameter at a position of the opening width in a direction of a rotation axis of each of the tapered rollers at at least a part of an inner diameter side of each of the pockets, and constitute a second engagement allowance in which an outer diameter-side opening width of each of the pockets becomes smaller than the roller diameter at a position of the opening width in the direction at at least a part of an outer diameter side of each of the pockets. Bumps are formed on an inner surface of the small diameter ring part in the pockets. Small diameter-side end faces of the tapered rollers facing the bumps are substantially flat surfaces.
