齿轮制造工艺过程一般分两个阶段:第一阶段是齿坯加工,要求加工出一定的几何形状;第二阶段是齿形加工,包括齿形的精整及按已切成的齿形对基准孔进行调整。第一阶段的加工必须保证基准孔与外圆的同心度;保证基准孔与一个基准端面的相互垂直(当齿轮叠块切齿时,保证与两个基准端面相互垂直)。第二阶段是劳动量最大的阶段,特别对齿面经渗炭及淬火的齿轮(M≥5)加工时尤为突出。齿形加工工艺是根据齿轮材料,热处理及啮合精度而定的,一
The gear manufacturing process is generally divided into two stages: the first stage is gear blank machining, requiring the processing of a certain geometric shape; the second stage is the tooth shape processing, including the tooth profile and the cut tooth profile on the basis of Hole to adjust. The first stage of machining must ensure that the reference hole and the cylindrical concentricity; to ensure that the reference hole and a reference end face perpendicular to each other (when the gear overlay block teeth, with two reference end face perpendicular to each other). The second stage is the most labor-intensive stage, especially for the tooth surface by the infiltration of carbon and quenching gear (M ≥ 5) processing is particularly prominent. Tooth processing technology is based on the gear material, heat treatment and meshing accuracy may be, a
