The function of the crankshaft is to convert the gas pressure transmitted from the piston-connecting rod assembly into torque for external output, and to drive the valve mechanism and other auxiliary devices. It is mostly made of high-quality medium carbon steel, medium alloy carbon steel, or ductile iron. The structure of the crankshaft includes the front end shaft, main journal, connecting rod journal, crank, balance weight, rear end shaft, etc., and there are oil passages running through the main journal, crank, and connecting rod journal to lubricate the main journal and connecting rod journal. Since it is subjected to various forces during use, there will be a certain amount of wear, and different parts have different wear characteristics.
