<P>PROBLEM TO BE SOLVED: To provide a conical roller bearing capable of eliminating various troubles attributable to accumulation of lubricating oil by suppressing occurrence of the accumulation of the lubricating oil in the bearing. <P>SOLUTION: In the conical roller bearing 21, a rolling element 29 with its outer circumferential surface being formed in a barrel-shaped projecting curved surface is used. Raceway surfaces 24, 27 of inner and outer rings 23, 26 are formed in a recessed curved surface capable of suppressing generation of any edge stress during the axial deviation of the inner and outer rings 23, 26. In a retainer 31, the large diameter side of a pocket 33 is formed in an open-comb shape, and a side surface 35a of a pocket column part 35 is formed in a recessed curved surface corresponding to the barrel-shaped projecting curved surface of the rolling element 29. Further, the opening width at an open end of the pocket 33 is set to be smaller than the outside diameter of an intermediate portion of the rolling element 29. <P>COPYRIGHT: (C)2009,JPO&INPIT |
