滚珠联轴器具有使用灵活、结构简单、制造方便、放率高等优点。它的主从动轴之间在联接时允许有较大的径向、轴向和角度位移量,因此具有较好的发展前途。本文简要介绍它的结构原理及承载能力和性能参数,供读者采用时参考。一、结构滚珠联轴器的结构原理见图1。轴1为扭矩输入轴,在它的外圆圆周上开有均布的圆弧槽,而钢套2的内圆表面上也开有同等数量而且是沿圆周均布的圆 Ball coupling has the advantages of flexible use, simple structure, easy manufacture and high discharge rate. Its primary and secondary driven shaft allows a large radial, axial and angular displacement when coupled, and therefore has a good future. This article briefly introduces its structural principle and carrying capacity and performance parameters for readers to use when reference. First, the structure of the principle of ball coupling shown in Figure 1. The shaft 1 is a torque input shaft which is provided with a uniform arc groove on the outer circumference of the shaft, while the inner circle surface of the steel sleeve 2 is also provided with the same number of round circles
