<p><P>PROBLEM TO BE SOLVED: To secure sufficient strength of a retainer even under conditions where heavy load, vibration impact load and combined load or the like is applied at relatively high speed rotation. <P>SOLUTION: The tapered roller bearing relating to "a" is composed of an inner ring 1 without a small flange, an outer ring 2, roller 3 of conical shape rolling element put therebetween, a cage type retainer 4 retaining the roller 3 and the roller 3 with a fixed interval and guided by the roller 3, and an elastic small flange ring 10 attached to the inner ring small raceway diameter side (inner raceway groove 7). Since the tapered roller bearing of a such construction is not provided with a small flange on a small raceway diameter side of the inner ring 1, the elastic small flange ring 10 can be easily installed on the inner ring small raceway diameter side part after rollers 3 of all rows are put in pockets of the cage type retainer 4 and are easily installed in the inner ring raceway groove 7 together. Consequently, tail part caulking or head part caulking of the retainer by pushing a bottom is not performed. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
