我厂生产的BAJ120农运车的齿轮在硬度测试中,由于行星齿轮和圆锥从动齿轮的表面光洁度太差,零件形状奇异,支撑面不好选择等原因,造成在HR-150型硬度计上不易甚至无法测试这两种齿轮的表面硬度.为此,我们为其设计了专用的硬度试验台.1 行星齿轮硬度专用台图1为行星齿轮零件简图.图2为行星齿轮专用硬度试验台工作图.
I produced the BAJ120 farm vehicles in the hardness test gear, the planetary gear and cone driven gear surface finish is too poor, the singular shape of the parts, the support surface is not good choice and other reasons, resulting in the HR-150 durometer Not easy or even impossible to test the surface hardness of these two gears.To this end, we designed a dedicated hardness test stand.1 planetary gear hardness dedicated table Figure 1 is a schematic view of the planetary gear components.Figure 2 for the planetary gear hardness test stand Work chart.
