Abstract:
In a method for manufacturing a multi-stage gear in which no gap is formed between a small-diameter gear and a large-diameter gear, there are included a first step of forming the small-diameter gear on an outer peripheral surface of a workpiece, a second step of forming a large-diameter gear part by plastically deforming an end portion of the workpiece to increase the diameter thereof, and a third step of forming the large-diameter gear by cutting the large-diameter gear part.
