Title: Mounting structure of rolling bearing
Inventor: UMEKAWA TAKAHIRO
IPC: F16C35/077
Filed: 2001-12-04
Abstract: <P>PROBLEM TO BE SOLVED: To solve such a problem of lowering of a degree of freedom for design that, since a conventional mounting structure has a cover ring fitted into an indentation formed to a center hole of a knuckle after an outer ring member is pressure-inserted into the knuckle, it requires length of the knuckle for the cover ring, while a bearing for an axle is miniaturized in an axial core direction.  <P>SOLUTION: A deformed part 30 of mounting a detachment-preventing member 28 is formed in a manner to be flexed to a main body 35, and in a combteeth-like shape. Since it is formed into an annular shape without need for installing a partial cut portion for reducing diameter to the detachment- preventing member 28, rigidity with a bearing for an axle mounted to a knuckle 23 is higher than the detachment-preventing member having the partially cut portion, to surely prevent detachment of the bearing for the axle. It is also possible to downsize the knuckle 23 and improve the degree of freedom for design by omitting the cover ring for preventing the bearing for the axle from being detached toward an outer side B.  <P>COPYRIGHT: (C)2003,JPO
