我厂生产电传打字机上输送纸带的齿轮(即输纸轮),其主要技术参数为:外径27.2mm;基圆直径25.5mm;根径25mm:齿数32:圆周速度1.5m/min;端面跳动不大于0.01mm;径向跳动不大于0.02mm;光洁度(?)6。过去加工方法过去的加工方法是用中间带有直径为1.1mm孔的端面立铣刀,将粗加工好的(即先用相应的滚刀滚出的渐开线齿轮)齿坯,用分度夹具在钻床上垂直进刀来加工。由于铣刀中间有一个直径1.1mm的孔,因此被加工的齿坯上只剩下了一个直径为1.1mm的圆
I plant the teletypewriter on the production of paper conveyor belt (ie, paper wheels), the main technical parameters: diameter 27.2mm; base diameter 25.5mm; diameter 25mm: number of teeth 32: peripheral speed 1.5m / min; End beat less than 0.01mm; Radial runout is not greater than 0.02mm; Finish (?) 6. The past processing methods in the past processing method is to use the middle with a diameter of 1.1mm hole end mill end, the rough (that is, with the corresponding hob rolled involute gear) Fixture in the drill on the vertical feed to processing. Due to the middle of the milling cutter there is a hole with a diameter of 1.1 mm, so only one circle with a diameter of 1.1 mm
