在自动机械中,广泛使用着凸轮,有时在一根轴上要安装若干个凸轮,若使用整体凸轮,则轴的结构会变得复杂,而且凸轮的装配、调试和维修也不方便。我们在这类设计中,采用了剖分式凸轮结构(见图1、图2),效果较好。使用剖分式凸轮后,轴可使用光轴而无须加工键槽或挡圈、定位锥孔等,消除了应力集中源,从而提高 In automatic machines, cams are used extensively. Sometimes several cams are mounted on a single shaft. If an integral cam is used, the structure of the shaft becomes complicated and the assembly, adjustment and maintenance of cams are not convenient. In this type of design, we use the split cam structure (see Figure 1, Figure 2), the effect is better. Using split cam, the shaft can use the optical axis without the need for processing keyway or ring, positioning cone hole, eliminating the stress concentration, thereby increasing
