摆线针轮行星传动减速器是一种新型的减速机械。摆线齿轮是其关键件(见图1、图2),它传递功率,承受较大的扭矩和接触应力,起动时承受一定的冲击负荷。因此,要求齿轮具有高硬度、高耐磨性、高接触疲劳强度和一定的韧性。一般多采用 GCr15钢制造。并按滚动轴承标准来控制热处理质量。即:硬度 Rc60—64;金相组织为隐晶马氏体十细的结晶马氏体十细小均匀的渗碳体,马氏体针小于三级。 Cycloid planetary gear reducer is a new type of deceleration machinery. Cycloid gear is the key component (see Figure 1, Figure 2), which delivers power, withstand greater torque and contact stress, start to withstand some impact load. Therefore, the gear is required to have high hardness, high wear resistance, high contact fatigue strength and a certain degree of toughness. Generally use more GCr15 steel. And by rolling bearing standards to control the quality of heat treatment. Namely: hardness Rc60-64; microstructure of cryptocrystalline martensite ten crystal martensite Ten small uniform cementite, martensitic needles less than three.
