Ductile iron flywheel housings generally use QT450-10, QT500-7 and QT600-3 materials. Grey cast iron flywheel housings generally use HT200 and HT250 materials.
The flywheel housing's main function is to bear the weight, position the engine and gearbox, and place the starting parts. Flywheel housing as a flywheel protection part, the hardness of raw materials must meet the specified standards. So it is usually made of cast iron, which is not easy to deform.
The machining methods of cast iron flywheel housing usually include turning, milling, drilling, tapping and thread cutting.
In the process of machining, there are specific requirements for aperture, verticality and positioning accuracy.
