为了消除X502铣床螺旋副间隙,我们采用了两段螺母的方法,取得了很好的效果。结构如图,在丝杠螺母圆周上四等分开键槽配键7(键不能凸出),再从中锯为左右两半,装在丝杠1上,配上键7一起装入支座3里。右丝杠螺母2以右身肩挂在支座的右侧;左丝杠螺母4以螺母5挂在支座的左侧,上紧螺母5调整2、4与丝杠1的活动间隙,丝杠1应能自由转动、左
In order to eliminate the X502 milling helical vice clearance, we have adopted two-nut method, and achieved good results. The structure is shown in the figure, on the circumference of the screw nut four equal keyway with the key 7 (key can not protrude), then from the saw for about half, mounted on the screw 1, together with the key 7 into the bearing 3 . The right screw nut 2 is attached to the right side of the supporter by the right shoulder; the left screw nut 4 is hung by the nut 5 on the left side of the supporter, the tightening nut 5 adjusts the movable gap between the screw 2 and the screw 1, Bar 1 should be able to rotate freely, left
