避けられないものであった。Conventional tapered roller bearing cages prevent the tapered rollers from falling off simply by assembling them into the cage.
In general, there are many sheet metal punched types as shown in Fig. 1, and after inserting the tapered rollers 3 into the pocket part 2 of the cage 1 from the inner diameter side, the tongue piece 4 provided on the small end side is shown in the figure. The tapered roller 3 is bent into a U-shape as shown in FIG.
The tongue piece 4 prevents it from falling off toward the outer diameter side, and the tongue piece 4 prevents it from falling off toward the inner diameter side. Therefore, the work of bending the same number of tongues as the number of rollers after the tapered rollers are assembled is extremely troublesome, and furthermore, it is necessary to form the gap between the tapered rollers and the tongues with high precision after the bending work. The bending work had to be carried out carefully and carefully, and these factors inevitably led to high costs.
