TAPERED ROLLER BEARING AND MANUFACTURING METHOD FOR TAPERED ROLLER BEARING

In a tapered roller bearing (1), neighboring pillar parts (13) constitute a first engagement allowance in which an inner diameter-side opening width of each of the pockets (P) becomes smaller than a roller diameter at a position of the opening width in a direction of a rotation axis (X) of each of t...

Zusammenfassung:	In a tapered roller bearing (1), neighboring pillar parts (13) constitute a first engagement allowance in which an inner diameter-side opening width of each of the pockets (P) becomes smaller than a roller diameter at a position of the opening width in a direction of a rotation axis (X) of each of the tapered rollers (4) at at least a part of an inner diameter side of each of the pockets (P), and constitute a second engagement allowance in which an outer diameter-side opening width of each of the pockets (P) becomes smaller than the roller diameter at a position of the opening width in the direction of the rotation axis (X) of each of the tapered rollers (4) at at least a part of an outer diameter side of each of the pockets (P). Bumps (21) are formed on an inner surface of the small diameter ring part (12) in the pockets (P). Small diameter-side end faces of the tapered rollers (4) facing the bumps (21) are substantially flat surfaces. Thereby, falling of the tapered roller from a cage can be reliably prevented.
