Abstract

Installation of a ball bearing into a cam requires that the radial play of the bearing (Fig. 1) be removed prior to gluing of the outer race in place. This is accomplished by providing a lateral load on the bearing while the glue is cured. In Fig. 2, the cam 10 is located on a tapered sleeve 11 which centers the hole in a locating pin 12. A precise fit with the pin locates the center of the bearing inner race 13. In Fig. 3, as inner race 14 is pushed downward with spring-loaded clamp 15, outer race 14 is pushed upward by spring-loaded sleeve 11 and is centered by the very precise balls 16 within the bearing. The unit is held in this position while glue 17 is applied fastening outer race 14 to cam 10.
