象模数为16、齿数为15这样一些大模数少齿数齿轮的加工,对于设备有限的工厂来说,确实有不少困难。我们在牛头刨上利用展成法的原理加工了这批齿轮,满足了生产需要。现将方法总结如下,供参考。展成法创齿的原理:所谓展成法,就是利用一对齿轮相互啮合时,其共轭齿廓互为包络线的原理来加工齿轮。如果使其中的一 Machining a few large-modulus, fewer-toothed gears, like the module number 16 and the number of teeth 15, does have a lot of difficulty for plants with limited equipment. We used the principle of exhibition law to process the gears on the bulldozer to meet the production needs. Now the method is summarized as follows for reference. Show the law of the tooth law: The so-called exhibition into law, is the use of a pair of gears intermeshing, the conjugate tooth profile of each envelope of the principle of processing gear. If you make one of them
