　　丝杠导轨是什么

　　What is a screw guide rail

　　丝杠导轨是高精密的直线传动产物。丝杠和导轨可配合组成一套直线运动系统；其中丝杠负责定位，并将旋转运动转换为直线运动，驱动导轨运动；导轨负责将 部件传输目标位置。

　　Screw guide is a high-precision linear transmission product. The screw and guide rail can be combined to form a linear motion system; The screw is responsible for positioning and converting rotational motion into linear motion, driving the guide rail motion; The guide rail is responsible for transporting the components to the target position.

　　滚珠丝杠按滚珠的循环方式，可分为外循环式和内循环式?内循环式：滚珠在循环过程中始终不脱离丝杠表面。内循环式结构设计简 单，螺母外径小，可进行微型设计。其优势在于滚珠运行阻力相对较小，灵敏度 优异；摩擦损失少，传动效率较高；滚珠回程较短，刚度较好，运转精度较高。因此适用于中小导程、中低速度场合，如 3D 打印机、中小型医疗扫描仪等。但内循环式返向器回珠槽为空间曲面，呈 S 形，加工较困难，对滚珠丝杠副的公称 直径、丝杠外径、螺纹滚道等加工要求较高。

　　Ball screws can be divided into external circulation type and internal circulation type according to the circulation mode of the balls? Internal circulation type: The ball never separates from the surface of the screw during the circulation process. The internal circulation structure design is simple, and the nut outer diameter is small, allowing for micro design. Its advantage lies in the relatively low resistance of ball operation and excellent sensitivity; Low friction loss and high transmission efficiency; The ball return is shorter, the stiffness is better, and the operating accuracy is higher. Therefore, it is suitable for small and medium-sized lead and medium low speed applications, such as 3D printers, small and medium-sized medical scanners, etc. However, the return groove of the internal circulation type ball screw is a spatial curved surface with an S-shape, which is difficult to process and requires high processing requirements for the nominal diameter, screw outer diameter, and thread raceway of the ball screw pair.

　　外循环式：滚珠在循环返回时离开了丝杠螺旋滚道而在螺母体内或体外循环。外循环式滚珠丝杠副尺寸较大，适用于载荷较大的场合，如大型重载机床。

　　External circulation type: The ball leaves the screw spiral raceway and circulates inside or outside the nut body during the return cycle. The external circulation ball screw pair has a relatively large size and is suitable for applications with high loads, such as large heavy-duty machine tools.
