The traditional way to manufacture the gashes of gear hob cutter is to mill it one by one, but the efficiency is quite low. With the proposed manufacturing process, the gashes could be generated by another specially designed hob cutter so that the manufacturing efficiency could be improved 2~3 times.

滾齒刀容屑槽之傳統(tǒng)加工方式https国产黄视免费，系利用成型銑刀逐槽加工而成，除加工時程冗長外日韩AV毛片精品簧片无码，銑制ZK 型蝸桿之缺點亦無法避免亚洲精品精品熟妇熟妇，本文再次利用滾制方式形成容屑槽免费看A片直接打开，并解決傳統(tǒng)制程上述之缺失。

Most of hob design for non-involute gears are nowadays taken by approximation method.For example,the normal sectional profile of hob worm therad is usually regarded approximately as its basic rack profile.Recently, some new methods have been developed in this respect but, perhaps, they appear overelaborate since the principle of spacing engagement is based on. For this reason , the paper offers a new design procedure for hob worm based on the planar engagement principle with the intention of simplific...
