Detailed Description
As shown in fig. 1-4, the radial thrust ball bearing with a punched outer ring of the present invention comprises a punched outer ring 01, a retainer 02, and a steel ball 03; the two ends of the punching outer ring 01 are respectively provided with a wide-mouth end 1-1 and a narrow-mouth end 1-2, the outer side of the wide-mouth end 1-1 of the punching outer ring 01 is provided with a circle of flange 1-3, and the joint of the narrow-mouth end 1-2 and the wide-mouth end 1-1 is arc-shaped to form a steel ball raceway; the retainer 02 comprises a retainer body end 2-1 and a mounting end 2-2, a row of freely rotatable steel balls 03 are mounted in the retainer body end 2-1, the retainer 02 plays a role in isolating rolling bodies, and the steel balls are limited by the size of pockets to fall out from the radial direction. The mounting end 2-2 extends out and is fixed on the inner side of the thin opening end 1-2 of the punching outer ring 01; one end of the steel ball 03 is exposed out of the outer diameter pocket of the retainer and is in line contact with the steel ball raceway of the drawn cup 01, the other end of the steel ball 03 is exposed out of the inner diameter pocket of the retainer, and the bearing inner ring is replaced by a shaft of a used part, which is consistent with the use condition of the drawn cup 01.
The wide-mouth end 1-1, the narrow-mouth end 1-2 and the flange 1-3 of the punching outer ring 01 are integrally formed by stretching thin-wall high-quality carbon steel strips, and various performance indexes of the surface of the punching outer ring after carburization quenching heat treatment reach the performance indexes of a turning and grinding entity outer ring of a ball bearing replaced by the punching outer ring, so that the problem of cost reduction is solved from the aspects of raw materials and processing technology. The outer ring process route is that the strip multi-station press can directly enter the assembly after stretching, heat treatment and string throwing, the utilization rate of raw materials is high, and the cost of the outer ring is reduced by about two thirds compared with the cost of the raw materials and the processing process of the outer ring of the solid lathing roller path for other ball bearings.
