我厂加工模数m=22,Z=21,β=10°30＇(左旋)齿轮时,精度等级要求8-7-7。在滚齿机上加工困难,所以用Y9650人字齿轮铣床加工,方法如下。齿坯4装在心轴8上(图1),基准端面与垫圈3(两端面平磨过)靠平。在齿坯端面上钻两个工艺螺孔(M16),双头螺栓2把齿坯4与心轴紧固成一体,再用两个压紧螺母7压紧齿坯。用机床卡盘夹紧心轴8,中心架9定位,用百分表5、10检测工件的上母线与侧母线,控制在0.02mm之内,并找正齿坯外圆跳动不大
I plant processing module m = 22, Z = 21, β = 10 ° 30 ’(L) gear, precision grade requirements 8-7-7. In the hobbing machine processing difficulties, so with Y9650 Herringbone milling machine, the method is as follows. Gear blank 4 mounted on the mandrel 8 (Figure 1), the reference end face and the washer 3 (both ends of the flat mill) by flat. Drill two process holes (M16) on the end face of the block. The stud 2 fastens the block 4 to the spindle and presses the block with two clamping nuts 7. With the machine tool chuck clamping mandrel 8, the center frame 9 positioning, with the detection of the workpiece on the dial 5,10 bus and side bus bar, control within 0.02mm,
