Medium frequency heat treatment process for flywheel ring gear heat treatment using medium frequency induction heating power supply

The flywheel is a disc with a large moment of inertia. There is a ring gear pressed on the outer edge, which meshes with the drive gear of the starter and is used by the starter. This ring gear is called the flywheel ring gear. There are two heat treatment methods for flywheel ring gear, one is high-frequency induction heating and the other is medium-frequency induction heating. Today, we will briefly talk about the medium frequency induction heating of the flywheel ring gear.

The intermediate frequency mass production of flywheel ring gear is carried out on a 160kw intermediate frequency induction heating power supply and CNC quenching machine tool equipment. Its parameters are in the table below. Because it is mass production, the residual temperature is 180°C and is tempered at low temperature using self-tempering technology.

(2)Quenching sensor and fixture. The inductor for medium frequency quenching of flywheel ring gear belongs to the ring type quenching inductor.

Since the intermediate frequency quenching machine uses upper and lower center positioning, in order to ensure that the workpiece rotates smoothly during the quenching process of the quenched parts, we designed a fixture to position the flywheel ring gear for induction quenching, and the effect is quite good.

As an important part of the engine and car, the flywheel ring gear seriously affects the operation of the entire car. Understanding the heat treatment process of flywheel ring gear helps us produce high-quality, long-life machinery.
