Title: Needle roller bearing, and speed reducer using the same needle roller bearing
Inventor: TANAKA MINORU
IPC: F16C33/46
Filed: 2003-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To eliminate limitation concerning material for a retainer 48 for needle roller bearings 44 and 45, and form it thin.  <P>SOLUTION: A radial inner end 48b of the retainer 48 is positioned apart radial outward from a radial outer end T of a slide contactable range S, so that axial move of a needle roller 52 is regulated by inner rings 36b and 37b, and a regulation flange 40. Large axial force generated by the needle roller 52 is not born by the retainer 48, but by the inner rings 36b and 37b and the regulation flange 40. As a result, rigidity of the retainer 48 can be low. Synthetic resin or the like can thus be selected for material for the retainer 48, and it can be formed thin.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
