How to confirm the "stroke" of the left and right ball screw? Jinan Gongrun Technology Co., Ltd. explains the calculation method of each stroke of the lower ball screw:

　　滚珠丝杆的行程有一个公式的，里面包含3个因素。

　　Ball screw stroke has a formula, which contains three factors.

　　1、丝杆螺纹长，2、有效行程， 3、余量长度。

　　1. Screw thread length, 2. Effective stroke, 3. Allowance length.

　　丝杆螺纹长=有效行程+螺母长+螺纹两头距离。

　　Thread length of screw = effective stroke + nut length + safe distance at both ends of thread.

　　总长=丝杆螺纹长+轴头加工长度

　　Total Length = Screw Thread Length + Shaft Head Processing Length

　　接下来，就说说各个因素所代表的含义是什么吧？

　　Next, what does each factor mean?

　　A、丝杆螺纹长：整根丝杆全部的螺纹长度；

　　A. Thread length of screw: Thread length of the whole screw;

　　B、有效行程：螺母从丝杆的这端移动到另一端所经过的距离；

　　B. Effective stroke: the distance the nut travels from one end of the screw rod to the other end;

　　C、余量长度：

　　C. Length of allowance:

　　1 、螺母的长度

　　1. Nut Length

　　2 、丝杆两端机加件干涉不能被螺母经过的长度

　　2. Length of the interference between the additives of the two ends of the screw that cannot be passed by the nut

　　3 、距离

　　3. Safe Distance

　　关于第3点补充说明，一般螺纹两头建议预留20mm左右的距离，1、此处有丝杆退热处理余热会导致沟槽有适量变形而不适合运行，2、20mm内处会适当加工扳手位不建议滚珠运行到此处，否则会产生磨损破裂。

　　As for the third point, it is generally recommended to reserve a safe distance of about 20 mm at both ends of the thread. 1. The residual heat of screw rod retreatment here will cause the groove to deform properly and not suitable for operation. The wrench position within 2 and 20 mm will be properly machined and the ball will not be recommended to run here, otherwise wear and tear will occur.
