在现代机器制造中和引进国外机械设备图纸时,常遇到变齿厚齿轮。如图1轧钢机接轴联轴器外齿套鼓形齿就是这样的齿轮。 普通滚齿过程中,只能加工出轴向齿厚不变的齿轮。为了加工出变齿厚齿轮,机床改装工作量比较大,还要按照齿厚变化规律制作靠模。微机数控技术的应用,大大简化了 In the modern machinery manufacturing and the introduction of foreign machinery and equipment drawings, often encountered variable tooth thickness gear. Figure 1 rolling mill shaft coupling gear teeth drum gear tooth is such a gear. Ordinary gear hobbing process, can only be processed out of gear with constant axial thickness. In order to process a thick tooth gear change, machine tool modification workload is relatively large, but also in accordance with the rules of tooth thickness changes by making the model. The application of microcomputer numerical control technology, greatly simplified
