机床齿轮是机床主要的精密传动零件之一。据统计,中型机床的齿轮一般占其基本件总数的5～16%;加工劳动量接近于整台机床总加工劳动量的17～24%;齿轮锻件重量约占机床锻件总重量的45%左右。加工精度要求高,产量大,技术关键多,早已成为有关技术、学术研究部门所注意的对象。 高速 Machine gears are one of the major precision drive components for machine tools. According to statistics, medium-sized machine tools generally account for 5-16% of the total number of basic parts; the amount of processing labor is close to 17-24% of the total processing labor of the entire machine tool; the weight of gear forgings accounts for about 45% of the total weight of machine tool forging . Processing requirements of high precision, large output, the key technology and more, has become the technology, academic research department of the object of attention. high speed
