计算滚齿机的分齿挂轮,有时会碰到这样的情况:1)好不容易配凑出来的一组挂轮,受机床结构的限制,齿轮或是太大,或是太小,无法啮合。2)计算出的挂轮比与欲求挂轮比相差2倍。3)加工齿数在200左右或200以上的齿轮需要用3对挂轮。碰到这类情况,不要轻易放弃已计算出的挂轮,利用e、f齿轮,这类问题大多数都可以解决。下面结合e、f齿轮的结构介绍如何运用e、f齿轮来计算分齿挂轮。 Calculate the gear hobbing machine gear, sometimes encounter such a situation: 1) Finally with a group of pegged out with a limited, machine tool structure, the gear is too large, or too small, can not mesh. 2) The difference between the calculated gear ratio and the desire gear ratio is 2 times. 3) The number of teeth in the processing of 200 or more than 200 need to use three pairs of wheels. In such cases, do not easily give up the wheel has been calculated, the use of e, f gear, most of these problems can be solved. The following combination of e, f gear structure describes how to use e, f gear to calculate the tooth gear.
