直線導(dǎo)軌可分為：滾輪直線導(dǎo)軌，圓柱直線導(dǎo)軌，滾珠直線導(dǎo)軌，三種，是用來支撐和引導(dǎo)運動部件，按給定的方向做往復(fù)直線運動。依按摩擦性質(zhì)而定，直線運動導(dǎo)軌可以分為滑動摩擦導(dǎo)軌、滾動摩擦導(dǎo)軌、彈性摩擦導(dǎo)軌、流體摩擦導(dǎo)軌等種類。
Linear guideways can be divided into three types: roller linear guideway, cylindrical linear guideway and ball linear guideway. They are used to support and guide moving parts to and fro in a given direction. According to the friction properties, linear motion guideways can be divided into sliding friction guideways, rolling friction guideways, elastic friction guideways, fluid friction guideways, etc.
滾珠絲杠是將回轉(zhuǎn)運動轉(zhuǎn)化為直線運動，或?qū)⒅本€運動轉(zhuǎn)化為回轉(zhuǎn)運動的理想的產(chǎn)品。滾珠絲杠是工具機械和精密機械上常使用的傳動元件，其主要功能是將旋轉(zhuǎn)運動轉(zhuǎn)換成線性運動，或?qū)⑴ぞ剞D(zhuǎn)換成軸向反復(fù)作用力，同時兼具高精度、可逆性和效率高的特點。由于具有很小的摩擦阻力，滾珠絲杠被廣泛應(yīng)用于各種工業(yè)設(shè)備和精密儀器。滾珠絲杠由螺桿、螺母、鋼球、預(yù)壓片、反向器、防塵器組成。它的功能是將旋轉(zhuǎn)運動轉(zhuǎn)化成直線運動，這是螺桿的進一步延伸和發(fā)展，這項發(fā)展的重要意義就是將軸承從滑動動作變成滾動動作。
Ball screw is an ideal product to convert rotary motion into linear motion or linear motion into rotary motion. Ball screw is a transmission element commonly used in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or torque into axial repeated force. At the same time, it has the characteristics of high precision, reversibility and high efficiency. Due to the small friction resistance, ball screws are widely used in various industrial equipment and precision instruments. The ball screw consists of a screw, a nut, a steel ball, a prepress plate, a reverser and a dust-proof device. Its function is to convert rotary motion into linear motion, which is the further extension and development of screw. The important significance of this development is to change the bearing from sliding motion to rolling motion.
直線導(dǎo)軌機械行業(yè)中的領(lǐng)軍工具，在機械式的工作中給人們帶來了很大的便利，我們今天要講的是直線導(dǎo)軌和滾珠絲桿大的區(qū)別是什么。
The leading tool in the linear guide machine industry has brought great convenience to people in the mechanical work. Today we want to talk about the big difference between linear guide and ball screw.
下面講到的是直線導(dǎo)軌精確性如何來判斷？
First of all, how to judge the accuracy of linear guide rail?
行走平行度主要是指將導(dǎo)軌用螺栓固定在基準(zhǔn)面上，讓滑塊在導(dǎo)軌全長上運行的時候，滑塊和導(dǎo)軌基準(zhǔn)面之間的平行度誤差。高度的成對相互差指的是組合在同平面上的各個滑塊的高度尺寸的大值與小值之差。寬度的成對相互差指的是裝在單支導(dǎo)軌上的每個滑塊與導(dǎo)軌基準(zhǔn)面之間的寬度尺寸的大值與小值之差。不同的設(shè)備可以選用不同精度的導(dǎo)軌。
Traveling parallelism mainly refers to the parallelism error between the sliding block and the guide rail datum plane when the guide rail is bolted to the datum plane and the sliding block runs on the full length of the guide rail. The height difference in pairs refers to the difference between the large value and the small value of the height dimensions of each slider combined on the same plane. The difference between pairs of widths refers to the difference between the large value and the small value of the width between each slider installed on a single guide rail and the guide rail datum plane. Different precision guides can be selected for different equipment.

直線導(dǎo)軌和滾珠絲桿區(qū)別：
Difference between linear guide and ball screw:
1.雖然同屬直線傳動設(shè)備，但是其工作原理、要求以及使用范圍都不一樣；
1. Although the same linear transmission equipment, its working principle, requirements and scope of use are different;
2.但兩者的表現(xiàn)在直線傳動方面表現(xiàn)卻都非常出色，絲桿主要用于一些機床大型設(shè)備、雕刻機械等較為普遍，非常方便的把旋轉(zhuǎn)的運動轉(zhuǎn)換成直線運動，用起來非常方便，從而減少整個設(shè)備在旋轉(zhuǎn)方面的磨損大大降低；
2. However, both of them are excellent in linear transmission. The screw rod is mainly used for some large machine tools and carving machines. It is very convenient to convert rotary motion into linear motion, which is very convenient to use, thus reducing the wear of the whole equipment in rotary motion;
3.直線導(dǎo)軌使用非常廣泛但種類很多，方型四排高珠導(dǎo)軌用于一些大型機床設(shè)備，如平面磨床，切片機、線切割等；也因工作條件的不同選用的直線導(dǎo)軌也是不同的，精密微型直線導(dǎo)軌LWL系列是一種超薄超輕型直線導(dǎo)軌。
3. Linear guideways are widely used but have many kinds. Square four row high bead guideways are used for some large machine tools, such as surface grinder, slicer, wire cutting, etc; The linear guideway selected is also different due to different working conditions. The precision miniature linear guideway LWL series is an ultra-thin and ultralight linear guideway.
適于精密測量儀器、半導(dǎo)體制造和檢驗設(shè)備、非標(biāo)自動化機械設(shè)備以及其他精密直線運動為重要的應(yīng)用場合等，因不同設(shè)備需要選擇正確的導(dǎo)軌也是關(guān)重要的。
It is suitable for precision measuring instruments, semiconductor manufacturing and inspection equipment, non-standard automatic mechanical equipment and other applications where precision linear motion is very important. It is also crucial to select the correct guide rail for different equipment.
