The invention discloses a machining technique used for a flywheel tooth disc of a double-mass flywheel. The machining technique comprises the following steps that strip material shearing-blanking and punching-sizing-spinning thickening-fine blanking-hobbing-heating treatment are conducted; a six-pass spinning thickening technique is selected and used for a spinning thickening technique, and spinning rollers of six different specifications are adopted for the six-pass spinning thickening technique; each spinning roller is in a short cylinder shape, and an inner groove with the connected tail and head and around the side face of a corresponding cylinder is formed in the middle position of the side face of each spinning roller and used for storing the edge of an original material piece in the spinning thickening technique; each inner groove comprises an upper end face, a lower end face and a connecting face; and the upper end face and the lower end face are planes, and the connecting face is an arc-shaped face. According to the machining technique used for the flywheel tooth disc of the double-mass flywheel, by adoption of the multi-pass spinning thickening technique, producing and machining of the flywheel tooth disc of the double-mass flywheel are conducted, the mechanical property and the overall physical property of the produced flywheel tooth disc are good, production efficiency is high, and production cost is low.
Description
technical field [0001] The invention belongs to the technical field of dual-mass flywheels, and in particular relates to a process for processing a flywheel toothed disc for a dual-mass flywheel. Background technique [0002] The dual-mass flywheel is a new type of torsional vibration damper for the drive train that has appeared in recent years. It adds the function of torsional vibration and vibration reduction to the traditional engine flywheel on the basis of the original function, and uses the change of its mass and stiffness to adjust the torsional vibration of the drive train. The inherent characteristics of vibration, and use its damping to attenuate the vibration amplitude of the system, reduce the vibration and noise of the vehicle, make the operation of the vehicle more stable and safe, and have been widely used in foreign cars. [0003] Since the flywheel plays an important role in the engine, as a core structural part, the mechanical properties of the parts have ...
