The ring gear is usually made of 45 or 40Cr steel. After heating, it is inlaid on the outer edge of the flywheel. After cooling, it is fastened on the outer edge of the flywheel. It is used to mesh with the starter gear, drive the crankshaft to rotate, and start the engine. During the working process, the ring gear is subject to huge friction, so we should enhance its surface wear resistance. How to enhance its surface wear resistance? Now, many manufacturers adopt the method of quenching and heat-treating the ring gear in an intermediate frequency heating furnace, and the effect is very good.
The medium frequency heating machine adopts voltage feedback series resonant circuit, adopts IGBT frequency conversion, and the conversion efficiency is as high as 97.5%. Compared with the thyristor, it can save energy by 10%-30%. It can start 99% successfully under any load, regardless of the size of the output power. , The power factor is always not less than 0.95, and the high power factor can always be guaranteed in the whole process, with a complete protection circuit and high working reliability. What’s even better is that it heats up very fast when quenching and heat-treating the ring gear. It only takes more than ten seconds to quench a ring gear. Such a fast speed effectively avoids the oxidation and decarburization of the ring gear during the quenching process. , to ensure the quenching effect of the ring gear.
In fact, the ring gear not only needs quenching heat treatment, it also needs diathermy heat treatment. The diathermy of the ring gear can also be completed with the medium frequency heating furnace, so that customers no longer need to worry about purchasing multiple equipment, and truly realize the multi-purpose of one machine.
