在船舶机器制造业的制品中,一般轴与轴套零件的连接形式都是通过键、销、槽或采用带安全过盈配合来实现。特殊的地方有用异形无键(非圆形)连接,异形无键连接的形式和优缺点在已出版的技术科学硕士吉姆切柯专著论文中有详细的论述。远在30年代,德国航空、机床制造、汽车和其他工业部门早就已经采用了摆线型线为基础的无键连接。50年代,为了建立无键连接,苏联就已经研制了新型的、工艺性更好的型线,叫做等轴轮廓线或 PK 型线。但由于没有专用的设备来加
In the marine machinery manufacturing products, the general shaft and sleeve parts are connected by key, pin, groove or with a secure interference fit to achieve. There are special shaped keyless (non-circular) connections in special places, and the forms and advantages and disadvantages of shaped keyless connections are discussed in detail in the published paper by Jim Scherke, the science and technology master. In the 1930s, German aviation, machine tool manufacturing, automotive and other industrial sectors already had a cycloid-based, keyless connection. In the 1950s, in order to establish a keyless connection, the Soviet Union had developed a new type of more technically shaped profile called Isometric Contour or PK Profile. But because there is no dedicated equipment to add
