滾珠絲杠是機(jī)床和精密機(jī)械中 常用的傳動(dòng)部件。其主要功能是將旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)換為直線運(yùn)動(dòng)，或?qū)⑴ぞ剞D(zhuǎn)換為軸向重復(fù)力，具有高精度，可逆性和率的特點(diǎn)。自滾珠絲杠開(kāi)發(fā)以來(lái)，它已廣泛應(yīng)用于精密機(jī)床，工業(yè)機(jī)械，電子機(jī)械，輸送機(jī)械等各種工業(yè)機(jī)械的定位精度控制。

Ball screw is a common transmission part in machine tools and precision machinery. Its main function is to convert rotary motion into linear motion or torque into axial repetitive force. It has the characteristics of high precision, reversibility and high efficiency. Since the development of ball screw, it has been widely used in precision machine tools, industrial machinery, electronic machinery, conveying machinery and other industrial machinery positioning accuracy control.

直線電機(jī)，也稱為直線電機(jī)，是各種領(lǐng)域制造商常用的一種機(jī)械設(shè)備。通過(guò)將它們安裝在生產(chǎn)設(shè)備上，可以為企業(yè)的生產(chǎn)線提供高速自動(dòng)直線運(yùn)動(dòng)，可以有效提高企業(yè)的生產(chǎn)能力。直線滑臺(tái)電機(jī)的特點(diǎn)是直線運(yùn)動(dòng)，而滾動(dòng)螺桿和旋轉(zhuǎn)電機(jī)間接產(chǎn)生直線運(yùn)動(dòng)。

Linear motor, also known as linear motor, is a kind of mechanical equipment commonly used by manufacturers in various fields. By installing them on the production equipment, it can provide high-speed automatic linear motion for the production line of the enterprise, which can effectively improve the production capacity of the enterprise. Linear slide motor is characterized by linear motion, while rolling screw and rotary motor produce linear motion indirectly.

讓我們導(dǎo)軌絲杠小編對(duì)這兩者的主要特征進(jìn)行一些比較：

Let's compare the main features of the two

1、速度，直線電機(jī)在速度方面具有相當(dāng)大的優(yōu)勢(shì)。直線電機(jī)的速度為300m / min;加速度為5G。滾珠絲杠的速度為100m/min。從速度和加速度的比較來(lái)看，直線電機(jī)具有相當(dāng)大的優(yōu)勢(shì)，并且直線電機(jī)在成功解決加熱問(wèn)題后將進(jìn)一步提高速度，并且"旋轉(zhuǎn)伺服電動(dòng)機(jī)+滾珠絲杠"的速度受到更多限制。很難改進(jìn)。在動(dòng)態(tài)響應(yīng)方面，由于運(yùn)動(dòng)慣性和間隙以及機(jī)構(gòu)復(fù)雜性等問(wèn)題，直線電機(jī)具有的優(yōu)勢(shì)。

1. Speed, linear motor has a considerable advantage in speed. The speed of the linear motor is 300m / min and the acceleration is 5g. The speed of ball screw is 100 m / min. From the comparison of speed and acceleration, the linear motor has considerable advantages, and the linear motor will further improve the speed after successfully solving the heating problem, and the speed of "rotary servo motor + ball screw" is more limited. It's hard to improve. In terms of dynamic response, linear motor has absolute advantages due to the problems of motion inertia, clearance and mechanism complexity.

2、在速度控制方面，直線電機(jī)響應(yīng)速度更快，速度范圍更寬， 高可達(dá)1:10000,可以在開(kāi)始時(shí)達(dá)到 大速度，并且可以高速快速停止。

2. In terms of speed control, the linear motor has a faster response speed and a wider speed range, up to 1:10000, which can reach a large speed at the beginning and stop at a high speed.

a、準(zhǔn)確性，在精度方面，直線電機(jī)由于傳動(dòng)機(jī)構(gòu)而具有簡(jiǎn)單的內(nèi)插滯后減小。通過(guò)位置檢測(cè)反饋控制，定位精度，再現(xiàn)精度和精度高于"旋轉(zhuǎn)伺服電機(jī)+滾珠絲杠",并且易于實(shí)現(xiàn)。 旋轉(zhuǎn)伺服電機(jī)+滾珠絲杠"是一種增壓傳動(dòng)部件。當(dāng)提供相同的扭矩時(shí)，線性馬達(dá)消耗的能量是"旋轉(zhuǎn)伺服馬達(dá)+滾珠螺桿"的兩倍。而且，直線電機(jī)的可靠性受控制系統(tǒng)穩(wěn)定性的影響，對(duì)周圍環(huán)境影響很大。因此，必須采取有效的磁隔離和保護(hù)措施來(lái)阻止磁場(chǎng)對(duì)滾動(dòng)導(dǎo)軌的影響和銑屑磁塵的吸附。

a. In the aspect of accuracy, the linear motor has a simple interpolation lag reduction due to the transmission mechanism. Through the position detection feedback control, the positioning accuracy, reproduction accuracy and absolute accuracy are higher than that of "rotary servo motor + ball screw", and easy to realize. "Rotary servo motor + ball screw" is a kind of energy-saving supercharging transmission parts. When providing the same torque, the energy consumption of linear motor is twice that of "rotary servo motor + ball screw". Moreover, the reliability of the linear motor is affected by the stability of the control system, which has a great impact on the surrounding environment. Therefore, effective magnetic isolation and protection measures must be taken to prevent the influence of magnetic field on rolling guide rail and the adsorption of milling dust.

b、直線電機(jī)噪音低，因?yàn)橹本€電機(jī)不受離心力的約束，運(yùn)動(dòng)過(guò)程中沒(méi)有機(jī)械接觸，沒(méi)有摩擦和噪音。傳動(dòng)部件不磨損，可大大減少機(jī)械損失，避免拖纜，電纜，齒輪，皮帶輪產(chǎn)生的噪音，提高整體效率。經(jīng)過(guò)長(zhǎng)時(shí)間的使用，滾珠絲杠在滾珠表面剝落，或滾珠絲杠軸有切割力表面的問(wèn)題，間接影響滾珠的運(yùn)行軌跡，造成滾珠間的摩擦，螺母和軸引起振動(dòng)。這樣噪音太大了。

b. The noise of linear motor is low, because linear motor is not constrained by centrifugal force, there is no mechanical contact, friction and noise in the process of movement. The transmission parts are not worn, which can greatly reduce the mechanical loss, avoid the noise generated by the streamer, cable, gear and pulley, and improve the overall efficiency. After a long time of use, the ball screw peels off on the surface of the ball, or the ball screw shaft has cutting force on the surface, which indirectly affects the trajectory of the ball, causing friction between the balls, and vibration between the nut and the shaft. It's too noisy.

c、行程：直線電機(jī)有效行程無(wú)限制，滾珠絲杠的螺母運(yùn)行到有效行程后，仍然可以正常旋轉(zhuǎn)，但在正常情況下，不能過(guò)度旋轉(zhuǎn)，否則會(huì)損壞滾珠絲杠，導(dǎo)致大量的滾珠顆粒和螺母掉落關(guān)閉。

c. Stroke: there is no limit to the effective stroke of linear motor. The nut of ball screw can still rotate normally when it reaches the effective stroke, but under normal circumstances, excessive rotation is not allowed, otherwise the ball screw will be damaged and a large number of ball particles and nuts will fall off and close.
