The guide rail is also called linear track, slide rail, linear guide rail and linear slide rail. It is used in the linear reciprocating motion, and can bear certain torque, and can realize high-precision linear motion under high load.

滾珠絲杠機(jī)構(gòu)作為一種高精度的傳動部件,大量應(yīng)用在數(shù)控機(jī)床、自動化加工電子精密機(jī)械進(jìn)給機(jī)構(gòu)、伺服機(jī)械手、工業(yè)裝配機(jī)器人、半導(dǎo)體生產(chǎn)設(shè)備、食品加工與包裝、醫(yī)療設(shè)備等各種領(lǐng)域。

Ball screw mechanism, as a high-precision transmission part, is widely used in CNC machine tools, electronic precision machinery feeding mechanism in automatic processing center, servo manipulator, industrial assembly robot, semiconductor production equipment, food processing and packaging, medical equipment and other fields.

直線導(dǎo)軌和滾珠絲桿同屬直線傳動設(shè)備，但是其工作原理、要求以及使用范圍都不一樣，但兩者的表現(xiàn)在直線傳動方面表現(xiàn)卻都非常出色。

Linear guide and ball screw are the same linear transmission equipment, but their working principle, requirements and scope of use are different, but both of them perform very well in linear transmission.

滾珠絲桿是工具機(jī)械和精密機(jī)械上更常使用的傳動元件，是由螺桿、螺母、鋼球、預(yù)壓片、反向器、防塵器組成。其主要功能是將旋轉(zhuǎn)運(yùn)動轉(zhuǎn)換成線性運(yùn)動，或?qū)⑴ぞ剞D(zhuǎn)換成軸向反復(fù)作用力，同時(shí)兼具高精度、可逆性和率的特點(diǎn)。主要用于一些機(jī)床大型備雕刻機(jī)械等較為普遍，非常方便的把旋轉(zhuǎn)的運(yùn)動轉(zhuǎn)換成直線運(yùn)動用起來非常方便，從而減少整個(gè)設(shè)備在旋轉(zhuǎn)方面的磨損大大降低。

Ball screw is the most commonly used transmission element in tool machinery and precision machinery, which is composed of screw, nut, steel ball, pre pressing plate, reverser and dust collector. The main function of the system is to convert the rotating motion into linear motion or the torque to axial repeated force, and it has the characteristics of high precision, reversibility and high efficiency. It is mainly used in some large machine tools for carving machines, which is very convenient to convert the rotating motion into linear motion, so as to reduce the wear of the whole equipment in the rotation.

1、與滑動絲桿副相比驅(qū)動力矩為1/3

1. The driving torque is 1/3 compared with the sliding screw pair

由于滾珠絲桿副的絲桿軸與絲母之間有很多滾珠在做滾動運(yùn)動,所以能得到較高的運(yùn)動效率.與過去的滑動絲桿副相比驅(qū)動力矩達(dá)到1/3以下,即達(dá)到同樣運(yùn)動結(jié)果所需的動力為使用滾動絲桿副的1/3.在省電方面很有幫助。

Because there are many balls in rolling motion between the screw shaft and the screw mother of the ball screw pair, the higher motion efficiency can be obtained. Compared with the past sliding screw pair, the driving torque reaches less than 1/3, that is, the power required to achieve the same motion result is 1 / 3 of the rolling screw pair. It is very helpful in saving power.

2、高精度的保證

2. High precision guarantee

滾珠絲桿副是用世界水平的機(jī)械設(shè)備連貫生產(chǎn)出來的,特別是在研削、組裝、檢查各工序的工廠環(huán)境方面,對溫度·濕度進(jìn)行了嚴(yán)格的控制,由于完善的品質(zhì)管理體制使精度得以充分保證.

Ball screw pairs are produced continuously with the world's highest level of mechanical equipment, especially in the aspects of grinding, assembling and checking the factory environment of each process. The temperature and humidity are strictly controlled. Due to the perfect quality management system, the accuracy can be fully guaranteed

3、微進(jìn)給可能

3. Micro feed possible

滾珠絲桿副由于是利用滾珠運(yùn)動,所以啟動力矩極小,不會出現(xiàn)滑動運(yùn)動那樣的爬行現(xiàn)象,能保證實(shí)現(xiàn)精確的微進(jìn)給.

Because ball screw pair uses ball motion, the starting torque is very small, and there will be no creeping phenomenon like sliding motion, which can ensure accurate micro feed

4、無側(cè)隙、剛性高

4. No side gap, high rigidity

滾珠絲桿副可以加予壓,由于予壓力可使軸向間隙達(dá)到負(fù)值,進(jìn)而得到較高的剛性(滾珠絲桿內(nèi)通過給滾珠加予壓力,在實(shí)際用于機(jī)械裝置等時(shí),由于滾珠的斥力可使絲母部的剛性增強(qiáng)).

The ball screw pair can be pressurized. Because of the pressure, the axial clearance can reach a negative value, and then get a higher rigidity (the ball screw can be applied with pressure to the ball, and the rigidity of the screw mother can be enhanced due to the repulsion force of the ball in the actual use of mechanical devices)

5、高速進(jìn)給可能

5. High speed feed possible

滾珠絲桿由于運(yùn)動效率高、發(fā)熱小、所以可實(shí)現(xiàn)高速進(jìn)給(運(yùn)動)。

Because of its high efficiency and small heat, ball screw can achieve high speed feed (motion).

直線導(dǎo)軌的特性

Characteristics of linear guide

1、定位精度高使用直線導(dǎo)軌作為線性導(dǎo)引時(shí)，由于直線導(dǎo)軌的摩擦方式為滾動摩擦，不僅摩擦系數(shù)降低滑動導(dǎo)引的1/50，動摩擦力與靜摩擦力的差距亦變得很小，因此當(dāng)床臺運(yùn)動時(shí)，不會有打滑的現(xiàn)象發(fā)生，可達(dá)到超高精密級（um）級定為精度。

1. When linear guide is used as linear guidance with high positioning accuracy, because the friction mode of linear guide is rolling friction, the friction coefficient is reduced to 1/50 of sliding guide, and the difference between dynamic friction and static friction is also very small. Therefore, when the bed moves, there will be no slippage, and the precision can be determined as the ultra-high precision level (UM).

2、磨耗少能長時(shí)間維持精度傳統(tǒng)的滑動引導(dǎo)，無可避免的會因油膜逆流作用造成平臺運(yùn)動精度不良，且因運(yùn)動時(shí)潤滑不充份，導(dǎo)致運(yùn)行軌道接觸面的磨損，嚴(yán)重影響精度，而滾動導(dǎo)引的磨耗非常小，故機(jī)臺能長時(shí)間維持精度。

2. The traditional sliding guide with low wear can maintain precision for a long time. It can not be avoided that the platform motion accuracy is poor due to the reverse flow of oil film, and the lubrication is not sufficient during the movement, which leads to the wear of the contact surface of the running track, which seriously affects the accuracy. However, the wear of rolling guide is very small, so the machine can maintain the precision for a long time.

3、使用高速度運(yùn)動且大幅降低機(jī)臺所需驅(qū)動馬力由于直線導(dǎo)軌移動摩擦力非常小，只需較小動力便能讓床臺運(yùn)行，尤其是在床臺的工作方式為經(jīng)常性往返運(yùn)動時(shí)，更能明顯降低機(jī)臺點(diǎn)力損耗量，且因其摩擦產(chǎn)生的熱度較小，可適用于高速運(yùn)行。

3. The high speed movement and the driving horsepower required for the machine are greatly reduced. Because the friction force of the linear guide rail is very small, it can make the bed run only with small power. Especially when the working mode of the bed is regular round-trip movement, the loss of the point force of the machine can be reduced obviously, and the heat produced by friction is small, so it can be applied to high-speed operation.

4、可同時(shí)承受上下左右的負(fù)荷由于直線導(dǎo)軌特殊的束制結(jié)構(gòu)設(shè)計(jì)，可同時(shí)承受上下左右方向的負(fù)荷，不想滑動導(dǎo)引在平行接觸面方向可承受的側(cè)向負(fù)荷輕，易造成機(jī)臺運(yùn)行精度不良。

4. It can bear the load of up and down at the same time. Because of the special beam structure design of linear guide rail, it can bear the load in the upper and lower left and right directions at the same time. It is not necessary to bear the light lateral load in the direction of parallel contact surface, which is easy to cause poor operation accuracy of the machine.

5、組裝容易并具互換性組裝時(shí)只要銑削或研磨床臺上導(dǎo)軌之裝配面，并依建議之步驟將導(dǎo)軌，滑塊分別特定扭力固定于機(jī)臺上，既能重視加工時(shí)的高精度，傳統(tǒng)的滑動導(dǎo)引，則須對運(yùn)行軌道加以鏟花，既費(fèi)事又費(fèi)時(shí)，且一旦機(jī)臺精度良，又必須在鏟花一次，直線導(dǎo)軌具有互換性，可分別更換滑塊或?qū)к壥侵本€導(dǎo)軌組，機(jī)臺即可重新獲得高精密度的引導(dǎo)。

5. When assembly is easy and interchangeable, only milling or grinding the assembly surface of guide rail on the table, and fixing the guide rail and slide block to the machine table with specific torque according to the recommended steps, not only can the high precision of machining be attached importance to, but the traditional sliding guide must be shoveled on the running track. It is not only difficult but also time consuming. Once the accuracy of the machine is good, it must be done once and straight-line guide must be carried out once The rails are interchangeable, and the sliders or guide rails can be replaced to straight track groups respectively, and the machine can obtain high precision guide again.

6、潤滑結(jié)構(gòu)簡單滑動引導(dǎo)若潤滑不足，將會照成接觸面金屬直接摩擦損耗床臺，而滑動導(dǎo)引要潤滑充足并不容易，需要在床臺適當(dāng)?shù)奈恢勉@孔供油，直線導(dǎo)軌則已在裝置油嘴，可直接以注油槍打入油脂，亦可換上專用油管接頭鏈接供油油管，以自動供油機(jī)潤滑。

6. If the lubrication structure is simple, if the lubrication is insufficient, it will be directly friction loss bed table according to the metal of contact surface. However, it is not easy to lubricate enough sliding guide. It is necessary to drill oil supply in proper position of bed table. Linear guide rail is already in the oil nozzle of the device, and oil can be directly injected with oil gun, and special oil pipe joint can be replaced to link oil supply pipe to lubricate the automatic oil supply machine.
