拒絕卡頓、損耗！導軌絲杠，決定設備精度與壽命的核心關鍵

　　Reject lagging and loss! Guide screw, the core key to determining equipment accuracy and lifespan

　　絲杠是一種機械傳動元件，通常用于將旋轉運動轉換為線性運動，主要由絲杠和螺母兩部分組成，絲杠是具有螺紋母線的長條狀零件，螺母則是一種外部具有螺紋母線的零件，螺母可以通過轉動絲杠來移動沿絲杠的方向。

　　A lead screw is a mechanical transmission component commonly used to convert rotational motion into linear motion. It is mainly composed of a lead screw and a nut. The lead screw is a long strip component with a threaded generatrix, while the nut is an external component with a threaded generatrix. The nut can move along the direction of the lead screw by rotating it.

　　絲杠廣泛應用于具有直線運動功能的機器設備中，電機通過聯軸器帶動絲杠軸轉動，絲杠軸上的螺母在螺旋形螺紋的驅動下實現直線往復運動，從而將電機的旋轉力矩轉化為設備運動所需要的直線方向的驅動力。

　　Screw is widely used in machines and equipment with linear motion function. The motor drives the screw shaft to rotate through a coupling, and the nut on the screw shaft achieves linear reciprocating motion under the drive of the spiral thread, thereby converting the rotational torque of the motor into the driving force in the linear direction required for equipment motion.

　　根據摩擦特性可以分為3種：即滑動絲杠、滾動絲杠和靜壓絲杠，滾動絲杠又分為滾珠絲杠和滾柱絲杠。其中，滑動絲杠中無滾動體，靠滑動摩擦傳遞推力，傳動效率較低；滾珠和滾柱絲杠具有鋼球或螺桿型的滾動體，靠滾動摩擦傳遞推力，傳動效率較高；靜壓絲杠為液體摩擦，適合于需要較高的進給推力以及具有頻繁振動負載的場合。針對滑動絲杠、滾珠絲杠和滾柱絲杠三者的差異可以簡單梳理成以下：

　　According to the friction characteristics, it can be divided into three types: sliding screw, rolling screw, and static pressure screw. Rolling screw is further divided into ball screw and roller screw. Among them, the sliding screw has no rolling elements and relies on sliding friction to transmit thrust, resulting in lower transmission efficiency; Ball and roller screws have rolling elements of steel ball or screw type, which transmit thrust through rolling friction and have high transmission efficiency; Static pressure screw is liquid friction, suitable for situations that require high feed thrust and frequent vibration loads. The differences between sliding screws, ball screws, and roller screws can be simply summarized as follows:

　　滾珠絲杠傳動效率一般能達到90%-96%，約為滑動絲杠的2-4倍。行星滾柱絲杠在承載能力及壽命、在導程和空間、速度等方面均優于滾珠絲杠。

　　The transmission efficiency of ball screws can generally reach 90% -96%, which is about 2-4 times that of sliding screws. Planetary roller screws are superior to ball screws in terms of load-bearing capacity and lifespan, as well as in terms of lead, space, and speed.

　　（一）滾珠絲杠滾珠絲杠由于高精度、結構緊湊的特點，適用于靈巧手的設計。當螺母旋轉時，滾珠在螺桿與螺母之間的螺紋滾道內循環滾動，從而驅動螺母實現平穩的直線運動。通過以滾動摩擦替代滑動摩擦，該結構顯著降低了摩擦阻力，具有傳動效率高、定位精度優、傳動可逆以及使用壽命長等優點，因而廣泛應用于工業設備、精密儀器、數控機床和機器人等領域。

　　（1） Ball screws are suitable for the design of dexterous hands due to their high precision and compact structure. When the nut rotates, the ball circulates and rolls in the threaded raceway between the screw and the nut, thereby driving the nut to achieve smooth linear motion. By replacing sliding friction with rolling friction, this structure significantly reduces frictional resistance and has advantages such as high transmission efficiency, excellent positioning accuracy, reversible transmission, and long service life. Therefore, it is widely used in industrial equipment, precision instruments, CNC machine tools, and robots.

　　（二）滾柱絲杠根據不同的結構設計，滾柱絲杠分為標準式、反向式、循環式、差動式、軸承環式。標準式行星滾柱絲杠主要應用于精密機床、機器人、軍工裝備等領域，是目前應用廣泛的類型；反向式行星滾柱絲杠多應用于航空、航天、船舶、電力等領域；循環式行星滾柱絲杠主要應用于要求高剛度、高承載、高精度的場合，如醫療器械、光學精密儀器等領域；差動式行星滾柱絲杠適用于傳動比較大，承載能力較高的應用場合；軸承環式行星滾柱絲杠主要適用于高承載、率等場合，如石油化工、重型機械等領域。

　　（2） According to different structural designs, roller screws are divided into standard, reverse, cyclic, differential, and bearing ring types. The standard planetary roller screw is mainly used in precision machine tools, robots, military equipment and other fields, and is currently the most widely used type; Reverse planetary roller screw is widely used in aviation, aerospace, shipbuilding, power and other fields; The cyclic planetary roller screw is mainly used in applications that require high stiffness, high load-bearing capacity, and high precision, such as medical devices, optical precision instruments, and other fields; Differential planetary roller screw is suitable for applications with large transmission ratios and high load-bearing capacity; The bearing ring planetary roller screw is mainly suitable for high load capacity, high efficiency and other applications, such as petrochemicals, heavy machinery and other fields.
