在現(xiàn)代工業(yè)制造的精密體系中，導(dǎo)軌絲杠宛如隱藏在設(shè)備內(nèi)部的精密 “工匠”，雖不引人注目，卻對設(shè)備的精準(zhǔn)運(yùn)行與生產(chǎn)起著關(guān)重要的作用。從自動化機(jī)床到高端 3D 打印機(jī)，從醫(yī)療器械到航空航天設(shè)備，導(dǎo)軌絲杠無處不在，為各類工業(yè)應(yīng)用提供穩(wěn)定、精確的線性運(yùn)動。

In the precision system of modern industrial manufacturing, the guide screw is like a precision "craftsman" hidden inside the equipment. Although not eye-catching, it plays a crucial role in the precise operation and efficient production of the equipment. From automated machine tools to high-end 3D printers, from medical equipment to aerospace equipment, guide screws are everywhere, providing stable and precise linear motion for various industrial applications.

工作原理?

Working principle

當(dāng)電機(jī)驅(qū)動絲杠旋轉(zhuǎn)時(shí)，螺母會沿著絲杠的軸向做直線運(yùn)動。在這個(gè)過程中，導(dǎo)軌起到導(dǎo)向和支撐的作用，確保螺母及與之相連的運(yùn)動部件能夠沿著預(yù)定的直線軌跡平穩(wěn)移動。對于滾珠絲杠，電機(jī)帶動絲杠旋轉(zhuǎn)，滾珠在絲杠和螺母的滾道內(nèi)滾動，同時(shí)推動螺母移動。滾珠的循環(huán)方式有內(nèi)循環(huán)和外循環(huán)兩種。內(nèi)循環(huán)是指滾珠在螺母內(nèi)部的循環(huán)通道內(nèi)循環(huán)，其結(jié)構(gòu)緊湊，噪音低；外循環(huán)則是滾珠通過外部的循環(huán)裝置進(jìn)行循環(huán)，適用于負(fù)載較大的場合。導(dǎo)軌絲杠的這種將旋轉(zhuǎn)運(yùn)動精確轉(zhuǎn)化為直線運(yùn)動的工作原理，為工業(yè)設(shè)備的各種精密操作提供了基礎(chǔ)。?

When the motor drives the screw to rotate, the nut will move in a straight line along the axial direction of the screw. In this process, the guide rail plays a guiding and supporting role, ensuring that the nut and its connected moving parts can move smoothly along the predetermined linear trajectory. For ball screws, the motor drives the screw to rotate, and the ball rolls in the raceway of the screw and nut, while pushing the nut to move. There are two ways for ball bearings to circulate: internal circulation and external circulation. Internal circulation refers to the circulation of the ball in the internal circulation channel of the nut, with a compact structure and low noise; External circulation refers to the circulation of balls through an external circulation device, which is suitable for situations with high loads. The working principle of the guide screw, which accurately converts rotational motion into linear motion, provides a foundation for various precision operations of industrial equipment. ?

The guide screw can achieve extremely high positioning accuracy, which is one of the key reasons for its wide application in many industrial fields. The accuracy of ball screws can reach micrometer level, and even achieve sub micrometer level positioning accuracy in some high-end applications. Through precise machining techniques and strict quality control, the thread pitch error of the screw and the straightness error of the guide rail are controlled within a very small range. For example, in semiconductor manufacturing equipment, processes such as ph
