RESIN CAGE FOR TAPERED ROLLER BEARING AND TAPERED ROLLER BEARING INCLUDING THE RESIN CAGE

RESIN CAGE FOR TAPERED ROLLER BEARING AND TAPERED ROLLER BEARING INCLUDING THE RESIN CAGE

In a tapered roller bearing-use resin made cage (10), a mold parting line (A) extending along the axial direction is formed in pillar sections (13) partitioning pockets (P). In opposing surfaces of adjacent pillar sections (13), on the outer diameter side beyond the mold parting line (A), an inner d...

Zusammenfassung:In a tapered roller bearing-use resin made cage (10), a mold parting line (A) extending along the axial direction is formed in pillar sections (13) partitioning pockets (P). In opposing surfaces of adjacent pillar sections (13), on the outer diameter side beyond the mold parting line (A), an inner diameter-side conical surface (15A) is formed in sliding contact with the outer peripheral surface of a tapered roller (4), and formed is a plane (16A) in the radial direction in an outer diameter-side portion beyond the inner diameter-side conical surface (15A). On the inner diameter side beyond the mold parting line (A), an outer diameter-side conical surface (15B) is formed in sliding contact with the outer peripheral surface of the tapered roller (4), and formed is a plane (16B) in the radial direction at an inner diameter-side portion beyond the outer diameter-side conical surface (15B). Due to this configuration, injection molding is made possible while maintaining a shape that enables a cage and roller.
