The Idling gear checkout equipment is Mitoyo contourgraph and tooth material of ZF7B, The product is the transmission structural steel, structural steel is generally divided into quenching and tempering structural steel and surface hardening structural steel.

Quenched and tempered structural steel the carbon content of this kind of steel is generally about 0.25%~0.55%. For the structural parts of the given section size, when quenched and tempered (quenching and tempering), if the quenched along the section, the mechanical properties are good. If not quenched, there is free ferrite in the microstructure, the toughness decreases.

For steel with temper brittleness tendency such as manganese steel, chromium steel, nickel chromium steel, after tempering should be fast cooling. The critical quenching diameters of these steels increase with the increase of grain size and alloying element content.

For example, 40Cr and 35SiMn steel is about 30~40mm, while 40CrNiMo and 30CrNi2MoV steel is about 60~100mm, often used to manufacture shafts, connecting rods and other structural parts that bear large loads.
