一、前言在齿轮加工领域中,一直采用切削加工的方法。虽然近年来国外在大批理齿轮生产中出现了新的加工方法,如冷轧、双刀盘切向切齿、拉外齿、多刀头插齿等等,但至今还没有得到广泛的应用,目前占主要地位的仍然是传统的滚齿和插齿工艺,如日本丰田汽车公司年产200多万辆汽车,生产变速箱齿轮也是用滚、插、剃齿加工方法。在大批量生产齿轮的汽车行业中,若每台变速箱平均按13个齿轮计算,一年生产700万辆汽车的话,仅仅切齿工序就需要采用1400台机床,因此迫切希望缩短切齿机床的循环时间,提高加工效率,如滚齿要求切 First, the foreword In the gear processing field, has been using cutting methods. Although in recent years a large number of foreign countries in the production of gear appeared new processing methods, such as cold-rolled, double-cutter tangential teeth, pull the external teeth, multi-head gear and so on, but so far it has not been widely used, The main status is still the traditional hobbing and gear cutting technology, such as Japan’s Toyota Motor Corporation with an annual output of more than 200 million vehicles, production gearbox gear is also used roll, insert, shaving processing methods. In the mass production gear industry, if an average of 13 gears per gearbox produces 7 million vehicles a year, only 1,400 machine tools are needed for the gear cutting operation alone, so there is an urgent need to shorten the cycle time of the gear cutting machine , Improve processing efficiency, such as hobbing request cut
