用插齿刀加工圆柱直齿轮(用展成法)在每次回程时,插齿刀齿后面可能与齿轮未加工的部分在一定的区域上接触。这个区域称为卡滞区。下面分析加工内啮合直齿轮时,插齿刀齿后面出现这种卡滞区的情况。卡滞区(如图1a)中粗黑色部分所示。总的卡滞区称为卡滞场(图1中划有剖面线部分)。在规定的工艺过程参数情况下,来确定降低插齿刀寿命的卡滞过程的剧烈程度。我们来研究插齿刀直离时的卡滞场(图1a) Machining a cylindrical spur gear with a gear shaper (with spreader method) The back of the gear shank may come in contact with the unmachined part of the gear over a certain area for each return stroke. This area is called a stuck area. The following analysis of the processing of internal gear spur gear, gear teeth after this kind of stuck area. As shown in the thick black part of the stuck area (Figure 1a). The total stuck area is called a stuck field (hatched section in Figure 1). In the case of the specified process parameters, to determine the severity of the arresting process that reduces the life of the gear cutter. We study the stagnation of the shaper when it leaves (Figure 1a)
