<p><P>PROBLEM TO BE SOLVED: To provide a conical roller bearing which can make the flow of the oil inside a bearing appropriate, and moreover, can allow the variations at the time of manufacturing to some extent. <P>SOLUTION: The conical roller bearing 1 has an outer ring 2, an inner ring 3, a plurality of conical rollers 4, and a retainer 5. The end part 12 on the small diameter side of the inner ring 3 is composed of a small diameter collar part 14 for regulating the axial movement of the conical roller 4 and a cylindrical part 15 whose diameter is smaller than the small diameter collar part 14 and which is continuous to the outside in the axial direction of the small diameter collar part 14. The end part 18 on the small diameter side of the retainer 5 has a bent part 19 bent radially internally. The bent part 19 is made to face the outer diameter of the cylindrical part 15 of the inner ring 3 at intervals so as to form a labyrinth in-between the inner ring 3. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
