<P>PROBLEM TO BE SOLVED: To provide a conical roller bearing in which durability is enhanced by preventing oil film shortage when being used oil bath lubrication. <P>SOLUTION: Small diameter flange parts 11, 12 are integrally formed in small diameter sides of each of inner rings 3, 4 and flange parts are not arranged in the large diameter sides of each of the inner rings 3, 4. Flange rings 13, 14 are fixed in each of end parts of the outer ring 2 as separate members. Sufficient amount of oil A is supplied to and held at the inner ring tracks 3a, 4a as shown by arrows when the conical roller bearing 1 is in the oil. The oil is prevented from flowing out outward in an axial direction by the flange rings 13, 14 and sufficient amount of oil is also supplied to and held at outer ring tracks 2a, 2b when conical roller bearing 1 comes out of the oil. <P>COPYRIGHT: (C)2012,JPO&INPIT |
