本文从非标准压力角齿条和渐开线齿轮啮合以及齿轮移距变位原理出发,对阿基米德蜗轮付进行了修正计算,从而在普通滚齿机上利用齿轮滚刀比较简单地解决了大模数多头蜗轮付的近似加工问题。该法较一般直接采取用齿轮滚刀加工未经修正计算蜗轮付的方法准确,较在铣床上用飞刀切制蜗轮加工法简单,对近似加工单件生产蜗轮付有一定的实用意义和参考价值。 In this paper, based on the principle of non-standard pressure angle rack and involute gear meshing and the gear shift displacement principle, the correction calculation of Archimedes worm gear is carried out, so that the use of gear hobbing cutter on ordinary gear hobbing machine solves the problem of large Approximate processing problems of modular multi - head worm gear. This method is generally more accurate than the direct use of gear hobs without compensation to calculate the worm pay method is more accurate than in the milling machine with a flying knife cut worm gear processing method is simple, the approximate processing of single production of worm gear pay certain practical significance and reference value.
