1.空气动力联轴器它是基于空气动力学原理基础上的联轴器,其特点是主动轴达到一定转速时才起到联轴的作用,具有限速功能。图1所示为气压弹性离心式联轴器,其工作原理如下: 当主动轴1旋转时,主动半联轴器2的叶轮3将压缩空气压入空心支管4中,空心支管在空气压力和离心力的作用下伸直并进入第一个从动半联轴器5的凹槽中,从而驱动从动轴7转动。当主动轴转速增加 1. Aerodynamic coupling It is based on the principle of aerodynamics coupling, which is characterized by a certain speed when the drive shaft to play a role in coupling, with speed limit. Figure 1 shows the pressure-elastic centrifugal coupling, which works as follows: When the drive shaft 1 is rotated, the active half-coupling 2 impeller 3 will be compressed air into the hollow branch 4, the hollow branch in the air pressure and Under the action of centrifugal force, extends straight into the groove of the first driven half-coupling 5 so as to drive the driven shaft 7 to rotate. When the drive shaft speed increases
