图1为常用的一组楔形离合器零件尺寸图。楔形离合器凸爪的侧面是一个倾斜于零件轴线的平面。由图2可知,只有两个离合器相啮合的凸爪侧面中线c_1c_1＇,c_2c_2＇通过轴线,才能保证一对楔形离合器的两凸爪侧面全部吻合,因此铣加工时,铣床操作者应按图3先将刀具尖角点调整到通过零件回转轴线,然后相对于凸爪向外移动一段e的距离,这样才能加工出符合要求的楔形凸爪。而图1所示的楔形离合器凸爪的标注方法存在着两个问题(无关尺寸不标注): 其一,凸爪的20°标注在齿根处,会使人错误地理解成在铣加工时,铣刀的尖角点调整到通过零件回
Figure 1 is a commonly used set of wedge clutch parts size. The side of the wedge clutch dog is a plane that is inclined to the axis of the part. Figure 2 shows that only two clutch meshing claw side of the centreline c_1c_1 ’, c_2c_2’ through the axis, in order to ensure a pair of wedge-shaped clutch on both sides of the dog all match, so milling, milling machine operator should be in Figure 3 Adjust the sharp point of the tool first to the axis of rotation through the part and then move it outward relative to the claw a distance of e so that the desired wedge claw can be machined. The wedge clutch claw shown in Figure 1, there are two methods of labeling (irrelevant dimensions do not mark): First, the claw 20 ° marked at the tooth root, people will mistakenly understood as the milling process The sharp point of the milling cutter is adjusted to return through the part
