Comparision of the bearing rings deformation after heat treatment

This thesis deals with deformations originating from heat treatment of the bearing metals. This is about the comparison of the heat treatment by rotating method in which the parts are feeded individ-ually into the rotating device and heat treated on hardening equipment in continuous way with high capacitive power. After the heat treatment it follows the operations of the grinding of the faces and diameters of the bearing rings. After the hardening we take into account two parameters, which may be mostly affected by hardening process namely: flatness of the faces ( cradle) and outer diameter ovality. Each of such deviations has got adverse influence during the grinding, therefore the hardening tech-nology is in most cases focused on elimination of this problem. The results of the heat treatment with higher deformations were confronted with values achieved by simulation software SYSWELD used for heat-metalurgical analysis.
