近几年来,大齿轮切齿用的机床和刀具有了很大的发展,因此目前加工大齿轮的方法和所使用的刀具也相应的有所变化。大齿轮的概念应理解为直径大于1000毫米和模数在10毫米以上的齿轮。在前一篇文章中已对成形粗铣和粗滚做了详细地论述,本文进一步对大齿轮的精加工进行讨论。精加工的目的是为了改善经过粗切的软的、调质的和淬硬的齿轮的周节、齿形、齿向和表面光洁度,以便达到予定的要求。同时,只应支付绝对必需的费用,因为精加工的费用是相当大的,例如,为了改善齿轮的工作平稳
In recent years, gear cutting machine with a large tool and the knife has made great progress, so the current method of processing gear and the tools used are also subject to change. The concept of gear should be understood as a gear with a diameter of more than 1000 mm and a modulus of more than 10 mm. In the previous article has been discussed in detail roughing and rough rolling roll, the paper further discussed the finishing of the gear. The purpose of finishing is to improve the perimeter, profile, tooth orientation and surface finish of rough, soft, tempered and hardened gears in order to meet the required requirements. At the same time, only the absolutely necessary costs should be paid because the cost of finishing is considerable, for example, in order to improve the smooth working of the gears
