在机修工作中以及在非标设计或工艺装备设计中,常常遇到为解决单件或小量蜗轮加工而发愁,专门去准备或购置蜗轮滚刀,在经济上和时间上都不合算;在不带切向进给的普通滚齿机上用飞刀方法加工蜗轮,在操作上相当麻烦且不易精确控制。开封机床厂杜琦亮同志79年在自制蜗杆旋风切削头的工作中,提出了用普通齿轮滚刀滚切蜗轮的办法并取得了良好效果。这种方法,郑州机械研究所试制工厂在生产某些非标设备中也得到多次采用,均获成功。只要滚刀直径不小于蜗杆直径、又不比蜗杆直径大得太多(不宜超过50％),将参数适当修改一下,就可以利用现有条件顺利地切制蜗杆传动副、装配时不必手工修刮,且传动灵活、温升较低,也有一定的承载能力。这些装备经多年生产使用考验,性能及寿命均堪令人满意。
In mechanical work and non-standard design or process equipment design, often encountered in order to solve the single or a small amount of worm gear processing worries, specifically to prepare or purchase worm hob, both economically and time are uneconomical; in The worm gear is machined on the common hobbing machine without tangential feed by flying knife, which is quite troublesome in operation and difficult to control accurately. Kaifeng Machine Tool Plant comrade Du Qi-liang 79 years in self-made worm cyclone cutting head work, put forward the use of ordinary gear hobbing cut worm wheel method and achieved good results. This method, Zhengzhou Institute of Machinery trial production plants in the production of certain non-standard equipment has also been used many times, have been successful. As long as the hob diameter is not less than the worm diameter, nor too much larger than the worm diameter (not more than 50%), the parameters appropriate to modify, you can use the existing conditions to successfully cut the worm drive Vice assembly without the need to manually scratch , And flexible transmission, low temperature rise, but also a certain carrying capacity. After years of production and use of these equipment test, performance and life expectancy are satisfactory.
