精密蜗杆的磨齿和检测是制造中的关键,最近,我厂借助一些通用量具,在精密车床上解决了仪器检测范围所不及的0级蜗杆的齿形,蜗杆长822mm,模数11,压力角15°。方法如下:首先调整好车床前、后顶尖,使中心线重合。置蜗杆于两顶尖之间(蜗杆外圆预先磨好,无锥度)。卸下车床方刀架,回转小刀架75,取一磁力表座及杠杆百分表吸在装刀架的安 Precision grinding and grinding worm detection is the key to manufacturing, recently, I plant with some common measuring tools, precision lathe to solve the instrument detection range less than the 0-level worm gear, worm length 822mm, modulus 11, the pressure Angle 15 °. As follows: First, adjust the lathe before, after the top, so that the center line coincide. Set the worm between the two tops (worm pre-polished cylindrical, non-tapered). Remove the lathe square knife holder, rotary knife holder 75, take a magnetic table seat and lever dial indicator suction mounted on the knife holder
