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:

　　滾珠絲桿的行程有一個公式的，里面包含3個因素。

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

　　1、絲桿螺紋長，2、有效行程， 3、余量長度。

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

　　絲桿螺紋長=有效行程+螺母長+螺紋兩頭安全距離。

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

　　總長=絲桿螺紋長+軸頭加工長度

　　Total Length = Screw Thread Length + Shaft Head Processing Length

　　接下來，就說說各個因素所代表的含義是什么吧？

　　Next, what does each factor mean?

　　A、絲桿螺紋長：整根絲桿全部的螺紋長度；

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

　　B、有效行程：螺母從絲桿的這端移動到另一端所經過的距離；

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

　　C、余量長度：

　　C. Length of allowance:

　　1 、螺母的長度

　　1. Nut Length

　　2 、絲桿兩端機加件干涉不能被螺母經過的長度

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

　　3 、安全距離

　　3. Safe Distance

　　關于第3點補充說明，一般螺紋兩頭建議預留20mm左右的安全距離，1、此處有絲桿退熱處理余熱會導致溝槽有適量變形而不適合運行，2、20mm內處會適當加工扳手位不建議滾珠運行到此處，否則會產生磨損破裂。

　　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.
