Reciprocating lead screw is a kind of lead screw that can make the slider realize reciprocating motion without changing the rotation direction of the main shaft. Double screw rod is a form of stereo cam, which is represented by two thread grooves with the same pitch and opposite direction. Both ends are connected by transition curve. Through the rotation of the screw rod, the sliding block placed in the spiral groove is pushed by the side of the spiral groove to make axial reciprocating motion.

丝杠或者叫做“丝杆”传动，是一种螺旋传动方式，滚珠丝杠（已基本取代梯形丝杆，俗称丝杆）是用来将旋转运动转化为直线运动；或将直线运动转化为旋转运动的执行元件，并具有传动效率高，定位准确等特点；当(滚珠)丝杠作为主动体时，螺母就会随丝杆的转动角度按照对应规格的导程转化成直线运动，被动工件可以通过螺母座和螺母连接，从而实现对应的直线运动。

The lead screw, or "screw" transmission, is a spiral transmission mode. The ball screw (which has basically replaced the trapezoidal lead screw, commonly known as the lead screw) is used to convert the rotary motion into linear motion; Or the actuator that converts linear motion into rotary motion, and has the characteristics of high transmission efficiency and accurate positioning; When the (ball) lead screw is used as the driving body, the nut will be transformed into linear motion according to the lead of the corresponding specification with the rotation angle of the lead screw. The passive workpiece can be connected with the nut through the nut seat, so as to realize the corresponding linear motion.

液压传动是利用液压泵将原动机的机械能转换为液体的压力能，通过液体压力能的变化来传递能量，经过各种控制阀和管路的传递，借助于液压执行元件(液压缸或马达)把液体压力能转换为机械能，从而驱动工作机构，实现直线往复运动和回转运动。

Hydraulic transmission is to use the hydraulic pump to convert the mechanical energy of the prime mover into liquid pressure energy, transfer energy through the change of liquid pressure energy, transfer through various control valves and pipelines, and convert the liquid pressure energy into mechanical energy with the help of hydraulic actuator (hydraulic cylinder or motor), so as to drive the working mechanism and realize linear reciprocating motion and rotary motion.

双向丝杠是在一根丝杠上制出两段旋向不同的螺纹，即一段右旋螺纹，一段左旋螺纹。旋在其上的右、左旋螺母，分别连接着运动机件。当丝杠旋转时，该两个运动机件随着螺母快速趋近或分离，从而产生要求的机械功能。双向丝杠排线均匀，能完全按设定的间距排线，往复换向可靠，当工字轮窄时短时间换向尤为突出，不存在误动作换向问题。排线推力大，不产生压丝，不会造成放不出丝现象。结构简单，制造方便。

Two way lead screw is to make two sections of threads with different rotation directions on one lead screw, that is, one section of right-hand thread and one section of left-hand thread. The right and left nuts screwed on them are respectively connected with the moving parts. When the lead screw rotates, the two moving parts quickly approach or separate with the nut, resulting in the required mechanical function. The two-way lead screw is evenly arranged, and can completely arrange the line according to the set spacing. The reciprocating reversing is reliable. When the I-wheel is narrow, the short-time reversing is particularly prominent, and there is no misoperation reversing problem. The wire arrangement thrust is large, which does not produce wire pressing and will not cause the phenomenon that the wire cannot be put out. The utility model has the advantages of simple structure and convenient manufacture.

丝杠车削加工成形，成本低，使用周期长，丝杠能连续使用多年不更换，只要换舟状导块，维修简便。恒排线距收卷或采用伺服电机传动可改变排线距，从始绕到满盘变排距收卷。交叉丝杠就是往复丝杠，就是以它的形状来定义的，就像叉号一样吧，也有人叫它为花轴，因为像花一样吧，还有人叫双向丝杠，因为它是左右的旋转的，提醒大家但是要和左右旋向两头旋转的区分开来，这个双向是左右的移动，而不是像两端左右的移动的。

The lead screw is formed by turning, with low cost and long service cycle. The lead screw can be used continuously for many years without replacement. As long as the boat guide block is replaced, the maintenance is simple. Constant winding distance or servo motor drive can change the winding distance and change the winding distance from the beginning to the full reel. The cross lead screw is a reciprocating lead screw, which is defined by its shape. It is like a cross. Some people call it a flower shaft, because it is like a flower. Others call it a two-way lead screw, because it rotates left and right. Remind everyone, but it should be distinguished from the one rotating left and right to both ends. This two-way movement is left and right, not left and right at both ends.
