在齿车床、螺纹磨床、万能铣床、滚齿机等带有较多交换齿轮的机床上,选配工件导程有零星小数值而导程的误差又较小的挂轮时,我们用下面简单的方法,可以很快地选择到齿数合理的挂轮:首先在这台机床的全部交换齿轮中,找出齿数合有相同质因数的齿轮,并将这些齿轮列表归纳。如在C8955(?)齿车床上,有35种不同齿数的46只交换齿轮,齿数分别为20,22……144。现将这35种齿轮的齿数全部进 In the lathe, thread grinder, universal milling machine, gear hobbing machine with more exchange gears on the machine, the selection of workpiece lead sporadic fractional value lead and the error of the smaller pulley, we use the following simple method , You can quickly choose a reasonable number of gear wheel: First of all in this machine exchange gear, find the gear with the same quality factor of the gear, and these gear list. As in the C8955 (?) Gear lathe, there are 35 kinds of 46 different gear exchange gear, the number of teeth were 20,22 ... 144. Now these 35 kinds of gear all the teeth into
