Abstract
Description

[0002] In actual bearing assembly production, when assembling a cylindrical roller bearing with a cage, pressure is used to embed the roller into the cage. The traditional way is to place the inner component on a work platform with a buffer layer, and then place the roller in the inner component retainer pocket, and use a rubber hammer to knock it into the cage to make it fit tightly. However, since the knocking will give the roller and the inner component a downward stress, and the inner component is placed on the platform, the roller on the opposite side will be squeezed against the inner ring of the bearing during the assembly and press-fitting of one side of the roller, causing the bearing roller and the inner raceway to be knocked and scratched, affecting the bearing quality. In addition, since the rollers are loaded manually by the assembler, it cannot be guaranteed that the force applied to each roller is consistent, which may also cause uneven tightness of the bearing roller assembly, thereby affecting the service life of the bearing. Against this background, the utility model provides a roller press-fitting device for cylindrical roller bearings with cages. Utility Model Content
