一、利用平衡块新产生的离心力的摩擦离合器(图1) 该装置的转筒1,采用键连接在从动轴上,并围绕固定轴2回转。带支杆4的星形轮5采用键连接在驱动轴上,同样围绕固定轴2回转。由于平衡块3能沿着星形轮5上的支杆4自由滑动, 当驱动轴达到限额转速时,在离心力的作用下,平衡块推向转筒1的内表面,从而带动从动轴一起转动。二、利用离心力的自动分离式摩擦离合器(图2) First, the use of balance block centrifugal force generated by the friction clutch (Figure 1) The device drum 1, using the key connected to the driven shaft, and revolves around the fixed shaft 2. The spider 5 with strut 4 is keyed to the drive shaft and also revolves around the stationary shaft 2. As the counterweight 3 can slide freely along the strut 4 on the star wheel 5, when the drive shaft reaches the limit rotation speed, the counterweight is pushed to the inner surface of the rotating drum 1 by the centrifugal force to drive the driven shaft together Turn. Second, the use of centrifugal force automatic separation friction clutch (Figure 2)
