Claims

[Scope of Claim for Utility Model Registration] (1) A plurality of tapered rollers are interposed between an inner ring and an outer ring each having a tapered raceway, and the tapered rollers are arranged at equal positions on the circumference using a synthetic resin cage. A tapered roller is provided with a flange for guiding the tapered rollers only on the large diameter portion of the inner ring, and a protrusion that engages with the flange is formed at a position corresponding to between the tapered rollers on the large diameter annular portion of the cage. In the bearing, the protrusion formed on the large-diameter annular portion of the retainer is bent inward in the radial direction at the tip, and the width and thickness of the tip are gradually tapered from the base; An inclined surface whose diameter increases from the inside of the bearing toward the outside is formed on the outer periphery of the bearing, and a retaining portion for the protruding portion is formed on the flange to maintain non-contact with the flange while the bearing is rotating. In the tapered roller bearing, the tip of the protruding portion is engaged with the engaging portion. (2) The tapered roller bearing according to claim (1), wherein the protruding portion is formed integrally with the large-diameter annular portion of the cage. (3) The tapered roller according to claim (1), in which the protruding portion is formed separately from the large-diameter annular portion of the cage and then integrally joined to the large-diameter annular portion. bearing. (4) According to any one of claims (1) to (3), the inner and outer surfaces of the protrusion are formed into curved surfaces consisting of circular arcs in the axial cross section of the cage. Three conical bearings. (5) Any one of claims (1) to (3) for registering a utility model, in which the inner and outer surfaces of the protrusion are formed by curved surfaces consisting of a plurality of planes in the axial cross section of the cage.
Tapered roller bearings listed in . (6) The tapered roller shaft according to any one of the utility model registration claims (1) to (5), in which the base of the protruding portion is also used as the large-diameter annular portion of the cage.
Received. (7) The tapered roller bearing according to any one of claims (1) to (5), wherein the protruding portion is provided on the outer end surface of the large-diameter annular portion of the cage. (8) The tapered roller bearing according to any one of claims (1) and (5), wherein the protruding portion is provided on the inner diameter surface of the large-diameter annular portion of the cage. (9) The tapered roller bearing according to any one of claims (1) to (8), wherein the inclined surface is formed by inclining the outer peripheral surface of the collar itself. 00) Utility model registration claim (1) in which the engaging portion is formed from a side step portion provided on the outer shoulder portion of the outer peripheral surface of the inner ring flange.
) to (9). (11) The tapered roller according to any one of the utility model registration claims (1) to (9), wherein the engaging portion is formed by a circumferential groove provided on the outer circumferential surface of the inner ring flange. bearing. 02) The tapered roller bearing according to any one of claims (1) to (9), wherein the engaging portion is formed from a side surface of a flange of the inner ring. . 03) Utility model registration claims (1) to (9) in which the engaging portion is formed from a circumferential groove provided on the side surface of the inner ring flange.
A tapered roller bearing according to any one of the above. 04) The outer peripheral surface of the collar is a cylindrical surface parallel to the axis, and a tapered ring whose diameter increases from the inside of the bearing toward the outside is formed on the outer peripheral surface, and a side step is provided at the outer end of the collar. Utility model registration claims (1) to (8) in which the outer peripheral surface of the tapered ring body is an inclined surface of the outer peripheral part of the collar, and the side step part is an engaging part. ) A tapered roller bearing as described in any one of the above.
