摘　　要：针对某款立式加工中心的电主轴配套编码器齿轮提出切实可行的逆向设计方法,对该逆向设计过程中的具体问题进行分析说明,并提出相应的解决方案。经现场多次实验验证,逆向设计所得编码器齿轮模型的齿型公差为0.007mm,单个齿距偏差为0.003mm,累积齿距偏差为0.0075mm,均符合《小模数渐开线圆柱齿轮精度》(GB2363-1990)中的6级精度要求。该设计方法可行有效,能够为后续其他型号编码器齿轮的逆向设计提供参考。A practical reverse design method for encoder gear of motorized spindle in a vertical machining center is proposed,and the specific problems in the reverse design process are analyzed and explained,and the corresponding solutions are put forward.Through many field experiments,the tooth profile tolerance of the encoder gear model obtained by reverse design is 0.007 mm,the single pitch deviation is 0.003 mm,and the cumulative pitch deviation is 0.0075 mm,all of which meet the 6-level accuracy requirements in“Precision of Small Modulus Involute Cylindrical Gear”(GB 2363-1990).This design method is feasible and effective,which can provide reference for the reverse design of other encoder gears.
