长锥距弧齿锥齿轮 ,由于其锥距超出机床加工范围 ,一直是齿轮加工中的一个难题。本文针对长锥距弧齿锥齿轮的加工特点 ,提出了不用变性机构加工长锥距弧齿锥齿轮的思想 ,将非零变位技术应用于长锥距弧齿锥齿轮的加工实践中。采用文中所述方法 ,研制出一对外锥距为 85 2 .6 5 2mm的非零变位长锥距弧齿锥齿轮。结果表明 ,在不改变现有机床的条件下 ,可加工出超出机床加工范围的长锥距弧齿锥齿轮
Long taper spiral bevel gear, because of its taper away from the scope of machining, gear machining has been a problem. In this paper, according to the processing characteristics of long taper spiral bevel gear, the idea of long taper bevel spiral bevel gear without denaturation mechanism is put forward, and the nonzero displacement technology is applied to the processing of long taper bevel spiral bevel gear. Using the method described in the article, a pair of non-zero displacement long taper spiral bevel gears with outside taper of 85 2 .65 2 mm were developed. The results show that without changing the existing machine tool conditions, machining can be processed beyond the scope of long taper spiral bevel gear
