Disclosed is a roll spinning forming device for a toothed part. The device is mounted on a machine tool body. A blank, a mandrel and a driving synchromesh gear are mounted on a machine tool spindle. A driven synchromesh gear and a roller are arranged in parallel on the spindle. The driven synchromesh gear and the roller are connected by a telescopic constant speed universal joint and rotate at a same angular speed. The driven synchromesh gear is driven by a spring mechanism in the radial direction, and the roller is driven by a servo motor assembly in the radial direction. Further disclosed is a roll spinning forming method for a toothed part, the rotating speed of the blank is maintained to be matched with the rotating speed of the roller according to a gear ratio during the movement of the roller toward the blank.
