目前国内使用的RC_0轴和RD_0轴的滚动轴承锁紧与防松装置(图1),大多采用如图2所示的19孔防松板(图1件1)卡在轴端键槽内,并用螺栓与如图3所示的紧定螺母(图1件2)相连接,从而达到滚动轴承 Currently used in the RC_0 axis and RD_0 axis of the rolling bearing locking and anti-loose device (Figure 1), most of the use of 19 holes as shown in Figure 2 anti-loose plate (Figure 1 1) stuck in the shaft end keyway, And the tightening nut (Figure 1, Figure 2) is connected to achieve the rolling bearing
