斜齿轮滚齿垫的高度,目前尚无比较实用的计算式,且制造后不能使用的情况偶有发生。现根据现场经验,将逆铣和顺铣时滚齿垫高度的计算和作图方法作一介绍、并以生产实例说明其应用。一、滚齿垫高度的计算式图1是滚齿切出时(顺铣切入)的示意图。滚刀切削斜齿轮时,啮合系数比在相同条件下的斜齿轮对近乎大1倍。被切齿轮的齿数越多,螺旋角越大,滚刀参与切削的刀齿数就越多,且分布在精切刀齿的两侧。此时,操作所选用的精切刀齿应尽量是滚刀中部的刀齿。另外,斜齿轮滚齿的操作步骤一般是先水平对刀,后转动刀架安装角,再滚齿。因此,顺铣切入
Helical gear hobbing pad height, there is no more practical formula, and can not be used after the occurrence of occasional occurrence. Now based on field experience, the vertical milling and smooth milling hobbing pad height calculation and mapping method for an introduction, and production examples to illustrate its application. First, the hobbing pad height calculation formula Figure 1 is a hobbing cut (cut-milling cut into) the schematic. Hob cutting helical gear, the meshing coefficient than the same conditions in the helical gear pair almost 1 times larger. The more teeth of the gear to be cut, the greater the helix angle, the more hobs will be involved in cutting, and the more teeth will be distributed on both sides of the cutter. At this point, the operation of the choice of precision cutter teeth should be as far as possible hob cutter teeth. In addition, helical gear hobbing steps are generally the first level of the knife, after turning the turret mounting angle, and hobbing. Therefore, cut into the mill
