| description | The invention discloses a gear carburizing and quenching heat treatment device which comprises a carburizing and quenching furnace, a composite rotating bearing piece, a heating mechanism, a first nozzle and a second nozzle. The composite rotating bearing piece is used for enabling the multiple cylindrical gear blanks to rotate with the central axis of the composite rotating bearing piece as the center and meanwhile enabling the single cylindrical gear blank to rotate with the central axis of the cylindrical gear blank as the center, and the first nozzle sprays carburizing gas to the peripheral surfaces of the multiple cylindrical gear blanks; the second nozzle sprays carburizing gas on the peripheral surfaces of the cylindrical gear blanks. According to the invention, a mode that the outer sides of a plurality of cylindrical gear blanks are synchronously rotated by utilizing the composite rotating bearing piece is utilized, so that the condition that the concentration of the outer sides of the plurality of c |
