| titleOfInvention | Method for manufacturing steel annular member |
| abstract | PROBLEM TO BE SOLVED: To realize a manufacturing method capable of obtaining a steel annular member such as a synchronizer ring, a rolling ring for a clutch release rolling bearing unit or the like at a low cost while ensuring sufficient shape accuracy and dimensional accuracy. When a steel material is subjected to a heat treatment for quenching and then cooled, the material is rapidly cooled to 200 to 350 ° C., and then a press with a processing rate of 3% or more is applied to the material. Apply processing. Based on this press working, distortion does not easily occur in the obtained intermediate material, and it becomes easy to ensure shape accuracy and dimensional accuracy. Furthermore, after the press working, the intermediate material is cooled to a temperature below the Ms point to cause martensitic transformation. Then, the hardness of the intermediate material is increased to a required value. [Selection] Figure 1 |
