SCIENCE AND TECHNOLOGY ENGLIAH FOR MECHANICAL ENGINEERING Plate Cams And Cylindrical Cams Plate cams are made in the shape of a flat plate with either a contoured periphery or a cylindrical periphery with a contoured groove in one face, and a hub. They rotate around an axis, which is perpendicular to the plane of the plate and they impart mainly radial motion to their followers 轮毂 Cylindrical cams consist of a cylindrical body designed to rotate around its axis, with either one end or a peripheral groove, shaped to impart the desired motion to a follower, and in a direction mainly parallel to the cylinder's axis There are other types of cams; these are, however outside the scope of this chapter

SCIENCE AND TECHNOLOGY ENGLIAH FOR MECHANICAL ENGINEERING Both plate and cylindrical cams have a wide field of application, and belong to the most efficient mechanisms known Cams of both types are used in both multispindle single and multispindle automatic screw machines and lathes for actuation of tool 多轴的 slides, in tool and die design, in internal automatic screw combustion engines for valve and machine Injector actuation, in various indexing 自动切丝机 devices, in packaging machinery, and in many other applications. Two plate cams acting on a single follower, one in the X direction. the other in the Y direction. can be designed to produce al most any follower path
