螺旋锥齿轮比直齿锥齿轮有重合系数大、传动平稳、承载能力高、寿命长等优点,大型螺旋锥齿在重型机器上广泛使用,我厂承担的650连轧机制造中,就有六对螺旋锥齿轮。锥齿轮的大端端面模数为34～36毫米,直径为1462～2481毫米,外锥距为1411～1612毫米。对于制造这样大型的螺旋锥齿轮,将一台精度失效的5米圆柱齿轮铣齿机改装成用指形铣刀加工大型直齿锥齿轮和螺旋齿锥齿轮的机床,改装后的铣齿
Spiral bevel gear than the straight bevel gear has a large coincidence coefficient, smooth transmission, high carrying capacity, long life and other advantages of large-scale spiral bevel gear widely used in heavy machinery, plant 650 bear mill manufacturing, there are six pairs Spiral bevel gear. Bevel gear large end face modulus of 34 to 36 mm, a diameter of 1462 ~ 2481 mm, an outer taper of 1411 ~ 1612 mm. For the manufacture of such a large spiral bevel gear, a precision-disabled 5-m spur gear milling machine was retrofitted into a machine for machining large straight spur bevel gears and helical bevel gears with a finger cutter, the modified milling gear
