在机械设备中,轴是最基本、也是最重要的组成部分之一.在各种类型的轴中,直轴最为常用,它们之间的转矩和运动的传递常常靠联轴器来实现.但在某些特定的使用场合,这种结构存在比较明显的缺点.因此,出现了一种直轴与直轴之间的新型连接,根据其结构特点,我们将这种组合体称之为复合轴. In mechanical equipment, the shaft is the most basic and one of the most important components.In all types of shafts, the straight shafts are most commonly used, and the transfer of torque and movement between them is often done with couplings. However, in some specific applications, this structure has the obvious shortcomings, therefore, there has been a new type of connection between the straight shaft and the straight shaft, and according to its structural features, we call this assembly as a composite axis.
