在普通滚齿机上滚切斜齿圆柱齿轮时，若出现差动挂轮的传动比小于滚齿机配换挂轮所能调整的最小传动比时，将会造成按正常加工方法无法选择差动挂轮。经过生产实践与研究，总结出了一种滚切这种情况下的斜齿国柱齿轮的调整计算方法，今介绍如下，和有关人士商讨。关键词##4斜齿圆柱齿轮;;差动挂轮传动比;;螺旋角;;模数
In general gear hobbing helical bevel gear, if there is less than the gear ratio of the gear changes less than the minimum gear ratio can be adjusted with the change gear, it will result in the normal processing method can not choose differential wheel. After production practice and research, summed up a kind of hobbing this case of helical gear adjustment, now introduced below, and the people concerned to discuss. Keywords 4 helical cylindrical gear; differential transmission gear ratio; helix angle; modulus
