我厂为百分表试制的YG3603型小模数滚齿机,使用中,走刀系统出现“爬行”。当滚切齿数较多的齿轮(如Z=120)时,齿厚出现“肥瘦”不均。以上两个问题成了该机床的致命伤。在对该机床进行精度分析的基础上,提出了一套提高机床使用精度的办法,并采取了相应的措施,解决了分齿肥瘦不均的问题;改进了走刀机构,彻底根治了爬行。这些方法经过几
I plant for the test model YG3603 small modulus hobbing machine, the use of the knife system “crawl ”. When the gear hobbing more gear (such as Z = 120), the tooth thickness “fat ” uneven. These two problems have become a fatal injury to the machine tool. Based on the accuracy analysis of this machine tool, a set of measures to improve the precision of machine tool is put forward, and corresponding measures are taken to solve the problem of uneven distribution of fat and fat. The invention improves the walk mechanism and completely eradicates the crawling. After these methods
