The gear precision of the gear shaft is 10 and the machining modulus is 1.7, The structure of gear shaft after normalizing is: F+S for hypoeutectoid steel, S for eutectoid steel, S+ secondary cementite for eutectoid steel, and it is discontinuous.
When quenching and tempering, the whole section of the workpiece is required to be thoroughly quenched, so that the workpiece can get fine needle-like quenched martensite. The microstructure of uniformly tempered sortensite was obtained by high temperature tempering. It is impossible for small factories to conduct metallographic analysis for each furnace, generally only hardness test, that is to say, the hardness after quenching must meet the hardness of the material, hardness after tempering according to the requirements of the drawing to check.
Selection of quenching temperature.
42CrMo steel, carbon content of 0.42%, belongs to hypoeutectoid steel, carbon content of 0.42% steel Ac3 is 800℃, from the hypoeutectoid steel quenching temperature requirements T=Ac3+30~50 (℃) can be obtained, quenching temperature T=830~850 (℃), we can set at 840℃.
