本文简要介绍美国格利森公司的大型弧齿锥齿轮加工机床。该公司早期生产的No.70型、No.91型机床是采用单刨刀加工弧齿锥齿轮的,这种机床加工的弧齿锥齿轮其齿线不是圆弧线。而近期试制成功的No.655型及已设计尚未试制的No.675型机床,是采用圆弧铣刀盘加工弧齿锥齿轮。采用铣刀盘加工弧齿锥齿轮,不但效率高,加工精度高, This article gives a brief introduction of Gleason’s large spiral bevel gear machining machine. The company’s earlier production of No.70, No. 91 machine is a single planer processing spiral bevel gear, the spiral bevel gear machining of this machine is not the tooth line arc. The successful trial of No.655 and the recent trial has not been designed No.675 machine tool is the use of arc milling cutter disc processing spiral bevel gear. The use of milling cutter spiral bevel gear processing, not only high efficiency, high precision machining,
