<p><P>PROBLEM TO BE SOLVED: To provide a tapered roller bearing having a simple structure easy to be manufactured and excellent rigidity, capable of improving of load capacity of the bearing and including a retainer constitutable into a size corresponding to needs at a low cost. <P>SOLUTION: This tapered roller bearing includes a hollow annular retainer 8 for holding a plurality of rolling elements 6 which are incorporated in a freely rolling manner along mutual bearing rings (an inner ring 2 and an outer ring 4) and have rolling surfaces 6s formed into truncated conical shapes. In a state of each rolling element 6 incorporated between the mutual bearing rings 2 and 4, an apex Ap of a cone angle of each rolling element 6 is converged on one point on a rotational axis Ax of the bearing. In each rolling element 6, a through-hole 66 passing from a head part side end face 6a to a tail part side end face 6b is punched along the rolling axis. The retainer 8 includes a plurality of pins 8p to be inserted one by one from the tail part side end face 6b into the through-hole 66 of each rolling element 6 and a hollow annular retainer body 8m for positioning and supporting each pin 8p at prescribed intervals along a peripheral direction. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
