- Abstract
In view of the problem that the internal defects in forgings are not detected during processing of original 40CrNiMoA cylindrical roller bearing solid cages, the thickness difference of step claws is often unqualified after milling outer step claws, and the variation of inner and outer diameters of cages in a single plane is out of tolerance after pulling square hole, the following improvement measures are put forward; adding water - immersion ultrasonic testing procedure after rough turning; changing milling outer step claw to grinding outer step claw, adding two-plane uniform grinding. processes, changing final turning inner diameter surface to grinding inner diameter surface; arranging pulling square hole before final grinding outer diameter surface, grinding inner diameter surface and turning outer step; limiting some tooling and processing parameters. The actual processing shows that the improved process can significantly improve the processing accuracy of cages and meet the processing requirements.
