由于用展成法加工齿轮有着很多的优点,所以近来制造齿轮大都采用这种方法,铇齿是展成法的一种,它除了具有一般展成法的优点外,还有一个特殊优点,就是能加工多级式的齿轮(如图2中的12),而铣切法和滚齿法都不能加工。目前我国滚齿机还不普遍,铇齿机更少有,因此,改装牛头铇床来刨齿是很有必要的。现在我来介绍一种把牛头铇床改装
Since the process of producing gears has many advantages, most of the gears used in recent years have been manufactured by this method. The teeth are one of the methods of exhibition. In addition to the advantages of the general exhibition method, there is a special advantage Can process multi-stage gear (Figure 12, 12), and milling and hobbing method can not be processed. At present, the gear hobbing machine in our country is not common yet, there are few gear spreaders. Therefore, it is necessary to modify the bulldozer bar to gear teeth. Now I will introduce a modification of the Tau Tau bed
