Because the needle teeth and cycloidal wheels are wear- resistant parts, relying on friction between each other to transmit power and speed, so the choice of GCr15 steel, that is, the representative steel grade of high carbon chromium bearing steel, its quenching and tempering hardness is high and uniform, with high wear resistance, high elastic limit and high contact fatigue strength, the basic parameters of CGr15 material are shown in Table 2.	cache/ajst-20201.pdf	txt/ajst-20201.txt
