Description

TECHNICAL FIELD

[0001] The utility model relates to bearing assembly tool technical field, concretely relates to a cylindrical bearing assembly tool. BACKGROUND

[0002] In actual bearing assembly production, when assembling the cylindrical roller bearing with the retainer cover and the retainer seat, the rollers are first placed in the outer ring raceway. The traditional way is to directly place the outer ring on the platform, then place the rollers in the outer ring raceway, two assembly personnel first hold the rollers that have been placed in the outer ring raceway with hands, then gradually move away the hands, insert the inner ring to prevent the rollers from falling off, then gradually divide the roller gap and insert the retainer seat, and finally place the retainer cover. However, when manually placing the rollers, the direction of holding the rollers cannot be completely horizontal, which may cause the rollers to collide with the outer ring rib, resulting in scratches, especially for blackened bearings. Moreover, the outer ring rib cannot completely support the end face of the roller, and once the hands are released, the rollers will tilt and fall off from the outer ring raceway. Therefore, the assembly personnel must hold the rollers at all times, which tests the coordination and tacit understanding of the assembly personnel. After the inner ring is inserted, the rollers will not fall off, but the distribution position is uneven, and the position needs to be adjusted when inserting the retainer seat. At this time, because the position of the rollers is uneven, the rollers may be scratched again during the insertion of the retainer seat, thereby affecting the service life of the bearing and prolonging the assembly time. Therefore, we propose a cylindrical bearing assembly tool. SUMMARY
