本文介紹了有关瑞士Mikron公司所生产的小模数齿輪滚刀的問题。文中第一部分介紹圓柱齿輪滚刀的品种規格、结构特点和精度标准等;第二部分介紹连续切削加工直齿圆錐齿輪的“成形滚刀”,包括它的工作原理、刀具設計原則以及按照圓錐齿輪的“假想齿数”进行滾刀的分类表。最后簡要的介紹該厂制造齿輪滚刀的工艺方法,以及有关加工滚刀的机床和切齿机床的特性。 This article describes the issue of small module gear hobs produced by Mikron AG in Switzerland. The first part of the paper introduces the variety specifications, structural characteristics and accuracy standards of cylindrical gear hobs. The second part introduces the “forming hob” of continuous cutting straight bevel bevel gears, including its working principle, the principle of tool design, Gear “hypothetical number” hob classification table. Finally, a brief introduction of the factory manufacturing gear hob process, as well as the processing of hobbing machine and gear cutting machine characteristics.
