分享 hiwin 直线导轨的维护与保养的实用知识 Hiwin 直线导轨属于高精度的机械行业运用很多的五金工具,所以在运用的过程当中我 们也是需要去维护和保养它的,这样才能得到更好的工作。 Hiwin 直线导轨属于精密零件,因而在使用时要求有相当地慎重态度,即变是使用了高 性能的导轨,如果使用不当,也不能达到预期的性能效果,而且容易使导轨损坏。 使用 hiwin 直线导轨需要注意以下事项: 一、保持上银导轨及其周围环境的清洁 即使肉眼看不见的微笑灰尘进入导轨,也会增加导轨的磨损,振动和噪声。 二、使用安装时要认真仔细 不允许强力冲压,不允许用锤直接敲击导轨,不允许通过滚动体传递压力。 三、使用合适、准确的安装工具 尽量使用专用工具,极力避免使用布类和短纤维之类的东西。 四、防止导轨的锈蚀 直接用手拿取导轨时,要充分洗去手上的汗液,并涂以优质矿物油后再进行操作,在雨 季和夏季尤其要注意防锈。 不过,在某种特殊的操作条件下,导轨可以获得较长于传统计算的寿命,特别是在轻负 荷的情况下。这些特殊的操作条件就是,当滚动面(轨道及滚动件)被一润滑油膜有效地分 隔及限制污染物所可能导致的表面破坏。事实上,在理想的条件下,所谓永久导轨寿命是可 能的。 脂润滑有预先在密封型导轨中充填润滑脂的密封方式,以及在外壳内部充填适量润滑 脂,每隔一段时间进行补充或更换的充填供脂方式。此外,对有多处导轨需要润滑的机械, 还采用管道连接至各润滑处的集中供脂方式。 脂润滑可做到充填一次润滑脂后长时间不需补 充,而且其密封装置的结构也较简单,因此使用广泛。油润滑相对来说比较简单。经常润滑 可以大大提高上银导轨的使用寿命。 这些工具也是需要维护和保养的,只有把他们维护好了才能更好的为我们工作。

上银HIWIN直线导轨HG系列
HIWIN直线导轨HG系列HIWIN直线导轨系为一种滚动导引,借由钢珠在滑块与导轨之间作无限滚动循环,负载平台能沿着导轨轻易地以高精度作线性运动。
与传统的滑动导引相比较,滚动导引的摩擦系数可降低至原来的1/50,由于启动的摩擦力大大减少,相对的较少无效运动发生,故能轻易达到μm级进给及定位。
再加上滑块与导轨间的束制单元设计,使得直线导轨可同时承受上下左右等各方向的负荷,上述陈列特点并非传统滑动导引所能比拟,因此机台若能派和滚珠螺杆,使用直线导轨作导引,必能大幅提高设备精度与机械效能。
HIWIN直线导轨优点及特点:1.定位精度高使用直线导轨作为线性导引时,由于直线导轨的摩擦方式为滚动摩擦,不仅摩擦系数降低至滑动导引的1/50,动摩擦力与静摩擦力的差距亦变得很小。
因此当床台运行时,不会有打滑的现象发生,可达到μm级的定位精度。
2.磨耗少能长时间维持精度传统的滑动导引,无可避免的会因油腻逆流作用造成平台运动精度不良,且因运动时润滑不充分,导致运行轨道接触面的磨损,严重影响精度。
而滚动导引的磨耗非常小,故机台能长时间维持精度。
3.适用高速运动且大幅降低机台所需驱动马力由于直线导轨移动时摩擦力非常小,只需较小动力便能让床台运行,尤其是在床台的工作方式为经常性往返运行时,更能明显降低机台电力损耗量。
且因其摩擦产生的热较小,可适用于高速运行。
4.可同时承受上下左右方向的负荷由于直线导轨特殊的束制结构设计,可同时承受上下左右方向的负荷,不像滑动导引在平行接触面方向可承受的侧向负荷较轻,易造成机台运行精度不良。
5.组装容易并具互换性组装时只要铣削或研磨床台上导轨之装配面,并依建议之步骤将导轨、滑块分别以特定扭力固定于机台上,即能重现加工时的高精密度。
传统的滑动导引,则须对运行轨道加以铲花,既费事又费时,且一旦机台精度不良,又必须再铲花一次。
直线导轨具有互换性,可分别更换滑块或导轨甚至是直线导轨组,机台即可重新获得高精密度的导引。

台湾上银HIWIN直线导轨的安装方法
上银导轨的安装方法:上银直线导轨作为数控机床的进给传动链,其装配形式和精度决定了数控机床的定位精度,也影响着进给轴插补运行的平稳性。
一、上银直线导轨安装形式及受力控机床进给轴常见的导轨支撑有如下几种形式:1、一端固定——一端自由导轨一端固定,另一端自由。
固定端轴承同时承受轴向力和径向力,这种支承方式用于行程小的短导轨或者用于全闭环的机床,因为这种结构的机械定位精度是最不可靠的,特别是对于长径比大的导轨(直线导轨相对细长),热变性是很明显的,1.5m长的导轨在冷、热的不同环境下变化0.05~0.10mm是很正常的。
但是由于他的结构简单,安装调试方便,许多高精度机床仍然采用这种结构,但是必须加装光栅,采用全闭环反馈。
2、一端固定——另一端支承上银导轨一端固定,另一端支承。
固定端同时承受轴向力和径向力;支承端只承受径向力,而且能作微量的轴向浮动,可以减少或避免因导轨自重而出现的弯曲,同时导轨热变形可以自由的向一端伸长。
这种结构使用最广泛,目前国内中小型数控车床、立式加工中心等均采用这种结构。
3、两端固定上银导轨两端均固定。
固定端轴承都可以同时承受轴向力,这种支承方式,可以对上银导轨施加适当的预紧力,提高导轨支承刚度,可以部分补偿导轨的热变形。
对于大型机床、重型机床以及高精度镗铣床常采用此种方案。
但是,这种导轨的调整比较繁琐,如果两端的预紧力过大,将会导致导轨最终的行程比设计行程要长,螺距也要比设计螺距大。
如果两端锁母的预紧力不够,会导致相反的结果,并容易引起机床震动,精度降低。
所以,这类导轨在拆装时一定要按照原厂商说明书调整,或借助仪器(双频激光测量仪)调整。
二、上银直线导轨轴承的排列与命名首先我们了解典型的进给轴传动链,最终支撑直线导轨的是近端支承轴承和远端支承轴承,这两组轴承通过相互的作用,将轴向力顶住,也就是导轨轴成巧妙地运用了“角接触轴承”即可以承受径向力,又可以承受轴向力的双向受力特点。
当轴承内挡圈和外挡圈受到一组相反方向的作用力时,轴承钢珠承受着一对互为相反的作用力,从静力学的角度上看,当物体静止时,这一对作用力大小相等,方向相反。

一、基本資料
1-1 HIWIN 直線導軌優點及特點
1-1-1 優點
(1) 定位精度高
使用直線導軌作為線性導引時,由於直線導軌的摩擦方式為滾動摩擦,不僅摩擦係數降低至滑動導引的 1/50,動摩擦力與靜摩擦力的差距亦變得很小。因此當床台運行時,不會有打滑的現象發生,可達到µm級 的定位精度。
(2) 磨耗少能長時間維持精度
(6) 潤滑構造簡單
滑動導引若潤滑不足,將會造成接觸面金屬直接摩擦損耗床台,而滑動導引要潤滑充足並不容易,需要在床 台適當的位置鑽孔供油。直線導軌則已在滑塊上裝置油嘴,可直接以注油槍打入油脂,亦可換上專用油管接 頭連接供油油管,以自動供油機潤滑。

The coefficient of friction is only 1/50 of traditional contact, and the difference between the dynamic and the static coefficient of friction is small. Therefore, there would be no slippage while the load is moving.(2) Long life with high motion accuracyWith a traditional slide, errors in accuracy are caused by the counter flow of the oil film. Insufficient lubrication causes wear between the contact surfaces, which become increasingly inaccurate. In contrast, rolling contact has little wear; therefore, machines can achieve a long life with highly accurate motion.(3) High speed motion is possible with a low driving forceBecause linear guideways have little friction resistance, only a small driving force is needed to move a load. This results in greater power savings, especially in the moving parts of a system. This is especially true for the reciprocating parts.(4) Equal loading capacity in all directionsWith this special design, these linear guideways can take loads in either the vertical or horizontal directions. Conventional linear slides can only take small loads in the direction parallel to the contact surface. They are also more likely to become inaccurate when they are subjected to these loads.(5) Easy installationInstalling a linear guideway is fairly easy. Grinding or milling the machine surface, following the recommended installation procedure, and tightening the bolts to their specified torque can achieve highly accurate linear motion.(6) Easy lubricationWith a traditional sliding system, insufficient lubrication causes wear on the contact surfaces. Also, it can be quite difficult to supply sufficient lubrication to the contact surfaces because finding an appropriate lubrication point is not very easy. With a linear motion guideway, grease can be easily supplied through the grease nipple on the linear guideway block. It is also possible to utilize a centralized oil lubrication system by piping the lubrication oil to the piping joint.(7) InterchangeabilityCompared with traditional boxways or v-groove slides, linear guideways can be easily replaced should any damage occur. for high precision grades consider ordering a matched, non-interchangeable, assembly of a block and rail.PrefaceA linear guideway allows a type of linear motion that utilizes rolling elements such as balls or rollers. By using re-circulating rolling elements between the rail and the block, a linear guideway can achieve high precision linear motion. Compared to a traditional slide, the coefficient of friction for a linear guideway is only 1/50. Because of the restraint effect between the rails and the blocks, linear guideways can take up loads in both the up/down and the left/right directions. With these features, linear guideways can greatly enhance moving accuracy, especially, when accompanied with precise ball screws.1-1 Advantages and Features of Linear Guideways1. General InformationG99TE17-13061Linear GuidewaysGeneral Information1-2 Selecting Linear GuidewaysG99TE17-13062(1) Static load rating (C 0)Localized permanent deformation will be caused between the raceway surface and the rolling elements when a linear guideway is subjected to an excessively large load or an impact load while either at rest or in motion. If the amount of this permanent deformation exceeds a certain limit, it becomes an obstacle to the smooth operation of the linear guideway. Generally, the definition of the basic static load rating is a static load of constant magnitude and direction resulting in a total permanent deformation of 0.0001 times the diameter of the rolling element and the raceway at the contact point subjected to the largest stress. The value is described in the dimension tables for each linear guideway. A designer can select a suitable linear guideway by referring to these tables. The maximum static load applied to a linear guideway must not exceed the basic static load rating.(2) Static permissible moment (M 0)The static permissible moment refers to a moment in a given direction and magnitude when the largest stress of the rolling elements in an applied system equals the stress induced by the static Load Rating. The static permissible moment in linear motion systems is defined for three directions: M R , M p and M Y .(1) Dynamic load rating (C)The basic dynamic load rating is an important factor used for calculation of service life of linear guideway. It is defined as the maximum load when the load that does not change in direction or magnitude and results in a nominal life of 50km of operation for a ball type linear guideway and 100km for a roller type linear guideway. The values for the basic dynamic load rating of each guideway are shown in dimension tables. They can be used to predict the service life for a selected linear guideway.(3) Static safety factorThis condition applys when the guideway system is static or under low speed motion. The static safety factor, which depends on environmental and operating conditions, must be taken into consideration. A larger safety factor is especially important for guideways subject to impact loads (see Table 1-1). The static load can be obtained by using Eq. 1.1f sL : static safety factor for simple load f sM : static safety factor for moment C 0 : static load rating (kN)M 0 : static permissible moment (kN •mm)p : Calculated working load (kN)M : Calculated appling moment (kN •mm)1-3 Basic Load Ratings of Linear Guideways1-3-1 Basic Static LoadEq.1.1f SL =P or 0f SM =M0M R M P M Y1-3-2 Basic Dynamic LoadG99TE17-13063Linear GuidewaysGeneral Information1-4 Service Life of Linear Guideways1-4-1 Service LifeWhen the raceway and the rolling elements of a linear guideway are continuously subjected to repeated stresses, the raceway surface shows fatigue. flaking will eventually occur. This is called fatigue flaking. The life of a linear guideway is defined as the total distance traveled until fatigue flaking appears on the surface of the raceway or rolling elements.1-4-2 Nominal Life (L)The service life varies greatly even when the linear motion guideways are manufactured in the same way or operated under the same motion conditions. for this reason, nominal life is used as the criteria for predicting the service life of a linear motion guideway. The nominal life is the total distance that 90% of a group of identical linear motion guideways, operated under identical conditions, can travel without flaking. When the basic dynamic rated load is applied to a linear motion guideway, the nominal life is 50km.1-4-3 Calculation of Nominal LifeThe acting load will affect the nominal life of a linear guideway. Based on the selected basic dynamic rated load and the actual load. The nominal life of ball type and roller type linear guideway can be calculated by Eq.1.2 and Eq. 1.3 respectively.If the environmental factors are taken into consideration, the nominal life is influenced greatly by the motion conditions, the hardness of the raceway, and the temperature of the linear guideway. The relationship between these factors is expressed in Eq.1.4 and Eq. 1.5.P P ( ( )) L=C P • 100km=• 62mileC P (())103103Eq.1.3L : Nominal lifeC : Basic dynamic load rating p : Actual loadL : Nominal life f h : Hardness factorC : Basic dynamic load rating f t : Temperature factor p C : Calculated load f W : Load factorEq.1.4Eq.1.5L= 33f h •f t •C f w • P cf h • f t • C f w • P c• 50km=•31mile(( )) f w P c f w P c (()) L=f h • f t •Cf w•P cf h • f t • C f w • P c• 100km=•62mile(())103103L=33C P• 50km=• 31mile C P( ( ) ) 1010Eq.1.2Ball type:Ball type:Roller type:Roller type:G99TE17-13064Table 1-2 Load factor1-4-5 Calculation of Service Life (L h )Transform the nominal life into the service life time by using speed and frequency.1-5 Applied Loads1-5-1 Calculation of Loadseveral factors affect the calculation of loads acting on a linear guideway (such as the position of the object's center of gravity, the thrust position, and the inertial forces at the time of start and stop). To obtain the correct loadvalue, each load condition should be carefully considered.(2) Temperature factor ( f t )Due to the temperature will affect the material of linear guide, therefore the permissible load will be reduced and the nominal service life will be decreased when over 100o C. Therefore, the basic dynamic and static load rating must be multiplied by the temperature factor. As some accessories are plastic which can’t resist high temperature, the working enviornment is recommended to be lower than 100o C.(3) Load factor ( f w )The loads acting on a linear guideway include the weight of slide, the inertia load at the times of start and stop, and the moment loads caused by overhanging. These load factors are especially difficult to estimate because of mechanical vibrations and impacts. Therefore, the load on a linear guideway should be divided by the empircal factor.TemperatureEq.1.6Eq.1.7L h = 3L •10 V e • 60 V e • 60= hr 3 3C P • 50•10( )V e • 60 V e • 60L h =3L • 10V e • 60V e • 60=hr3CP• 100•10()103L h : service life (hr)L : Nominal life (km)V e : speed (m/min)C/p : Load factorBall type:Roller type:1-4-4 Factors of Normal Life(1) Hardness factor ( f h )In general, the raceway surface in contact with the rolling elements must have the hardness of HRC 58~62 to an appropriate depth. When the specified hardness is not obtained, the permissible load is reduced and the nominal life is decreased. In this situation, the basic dynamic load rating and the basic static load rating must be multiplied by the hardness factor for calculation.G99TE17-13065Linear GuidewaysGeneral Information(1) Load on one blockTable 1-3 Calculation example of loads on blockW: Applied weightp n : Load (radial, reverse radial), n=1~4 a,b,k: Distance from external force to geometric center l: Distance from external force to driver f: External force p tn : Load (lateral), n=1~4c: Rail spacing d: Block spacing h: Distance from center of gravity to driverG99TE17-130661-5-2 Calculation of The Mean Load for Variable LoadingWhen the load on a linear guideway fluctuates greatly, the variable load condition must be considered in the life calculation. The definition of the mean load is the load equal to the bearing fatigue load under the variable loading conditions. It can be calculated by using table 1-5.(2) Loads with inertia forcesG99TE17-13067Linear GuidewaysGeneral Information=P e P +s P l=P e P +s 0.5 P l P s P l when when>•=P e P +l 0.5 P sP l P s>•1-5-3 Calculation for Bidirectional Equivalent LoadsHIWIN linear guideways can accept loads in several directions simultaneously. To calculate the service life of the guideway when the loads appear in multiple directions, calculate the equivalent load (p e ) by using the equationsbelow.lHG/EG/WE/QH/QE/QW/RG/QR SeriesMG Series1-5-4 Calculation Example for Service LifeA suitable linear guideway should be selected based on the acting load. The service life is calculated from the ratio ofthe working load and the basic dynamic load rating.Eq.1.8Eq.1.9Eq.1.10G99TE17-130681-6 FrictionAs mentioned in the preface, a linear guideway allows a type of rolling motion, which is achieved by using balls orrollers. The coefficient of friction for a linear guideway can be as little as 1/50 of a traditional slide. Generally, the coefficient of friction of ball type linear guideway is about 0.004 and roller type is about 0.003 .When a load is 10% or less than the basic static load rate, the most of the resistance comes from the grease viscosity and frictional resistance between balls. In contrast, if the load is more than the basic static load rating, the resistance will mainly come from the load.Eq.1.11=F µW •+S f : friction (kN)s : friction resistance (kN)µ : Coefficient of friction W : Normal loads (kN)G99TE17-13069Linear GuidewaysGeneral Information1-8 Jointed RailJointed rail should be installed by following the arrow sign and ordinal number which is marked on the surface of each rail.for matched pair, jointed rails, the jointed positions should be staggered. This will avoid accuracy problems due to discrepancies between the 2 rails (see figure).T : feeding frequency of oil (hour)V e : speed (m/min)1-7-2 OilThe recommended viscosity of oil is about 32~150cst. The standard grease nipple may be replaced by an oil piping joint for oil lubrication. since oil evaporates quicker than grease, the recommended oil feed rate is approximate 0.3cm 3/hr.1-7 Lubricationsupplying insufficient lubrication to the guideway will greatly reduce the service life due to an increase in rolling friction. The lubricant provides the following functions;Reduces the rolling friction between the contact surfaces to avoid abrasion and surface burning of the guideway.Generates a lubricant film between the rolling surfaces and decreases fatigue. Anti-corrosion .1-7-1 GreaseLinear guideway must be lubricated with the lithium soap based grease before installation. After the linear guideway is installed, we recommend that the guideway be re-lubricated every 100 km. It is possible to carry out the lubrication through the grease nipple. Generally, grease is applied for speeds that do not exceed 60 m/min faster speeds will require high-viscosity oil as a lubricant.T=100 • 1000V e • 60hrEq.1.12G99TE17-1306101-9 Mounting ConfigurationsLinear guideways have equal load ratings in the radial, reverse radial and lateral directions. The application depends on the machine requirements and load directions.Typical layouts for linear guideways are shown below:use of two rails(block fixed)HGW type block with mounting holes in different directions.total surface fixed installationuse of two rails(block movement)G99TE17-130611Linear GuidewaysGeneral InformationThree installation methods are recommended based on the required running accuracy and the degree of impacts and vibrations.1-10-1 Master and Subsidiary Guidefor non-interchangeable type Linear Guideways, there are some differences between the master guide and subsidiary guide.

上银导轨的工作原理
上银直线导轨又称线轨、滑轨、 线性导轨、线性滑轨,用于直线 往复运动场合,拥有比直线轴承 更高的额定负载, 同时可以承担 一定的扭矩,可在高负载的情况 下实现高精度的直线运动. 直线 运动导轨的作用是用来支撑和引 导运动部件,按给定的方向做往 复直线运动。依按摩擦性质而定, 直线运动导轨可以分为滑动摩擦 导轨、滚动摩擦导轨、弹性摩擦 导轨、流体摩擦导轨等种类。 ◎直线轴承主要用在自动化机械 上比较多,像德国进口的机床,纸 碗机,激光焊接机等等,当然直线 轴承和直线轴是配套用的.像上银 直线导轨主要是用在精度要求比 较高的机械结构上,
上银直线导轨的移动元件和固定元件之间不用中间 介质,而用滚动钢球。因为滚动钢球适应于高速运 动、摩擦系数小、灵敏度高,满足运动部件的工作 要求,如机床的刀架,拖板等。上银直线导轨系统 的固定元件(导轨)的基本功能如同轴承环,安装钢 球的支架,形状为“v”字形。支架包裹着导轨的顶 部和两侧面。为了支撑机床的工作部件,一套上银 直线导轨至少有四个支架。用于支撑大型的工作部 件,支架的数量可以多于四个。

滑块-使运动由曲线转变为直线。 新的导轨系统使机床可获得快速进 给速度,在主轴转速相同的情况下, 快速进给是上银直线导轨的特点。 上银直线导轨与平面导轨一样,有 两个基本元件;一个作为导向的为 固定元件,另一个是移动元件。由 于上银直线导轨是标准部件,对机 床制造厂来说.唯一要做的只是加 工一个安装导轨的平面和校调导轨 的平行度。当然,为了保证机床的 精度,床身或立柱少量的刮研是必 不可少的,在多数情况下,安装是 比较简单的。
作为导向的导轨为淬硬钢,经精磨后置于安装平面上。与平面导 轨比较,上银直线导轨横截面的几何形状,比平面导轨复杂,复 杂的原因是因为导轨上需要加工出沟槽,以利于滑动元件的移动, 沟槽的形状和数量,取决于机床要完成的功能。例如:一个既承 受直线作用力,又承受颠覆力矩的导轨系统,与仅承受直线作用 力的导轨相比.设计上有很大的不同。
上银HIWIN直线导轨HG系列
HIWIN直线导轨HG系列HIWIN直线导轨系为一种滚动导引,借由钢珠在滑块与导轨之间作无限滚动循环,负载平台能沿着导轨轻易地以高精度作线性运动。
与传统的滑动导引相比较,滚动导引的摩擦系数可降低至原来的1/50,由于启动的摩擦力大大减少,相对的较少无效运动发生,故能轻易达到μm级进给及定位。
再加上滑块与导轨间的束制单元设计,使得直线导轨可同时承受上下左右等各方向的负荷,上述陈列特点并非传统滑动导引所能比拟,因此机台若能派和滚珠螺杆,使用直线导轨作导引,必能大幅提高设备精度与机械效能。
HIWIN直线导轨优点及特点:1.定位精度高使用直线导轨作为线性导引时,由于直线导轨的摩擦方式为滚动摩擦,不仅摩擦系数降低至滑动导引的1/50,动摩擦力与静摩擦力的差距亦变得很小。
因此当床台运行时,不会有打滑的现象发生,可达到μm级的定位精度。
2.磨耗少能长时间维持精度传统的滑动导引,无可避免的会因油腻逆流作用造成平台运动精度不良,且因运动时润滑不充分,导致运行轨道接触面的磨损,严重影响精度。
而滚动导引的磨耗非常小,故机台能长时间维持精度。
3.适用高速运动且大幅降低机台所需驱动马力由于直线导轨移动时摩擦力非常小,只需较小动力便能让床台运行,尤其是在床台的工作方式为经常性往返运行时,更能明显降低机台电力损耗量。
且因其摩擦产生的热较小,可适用于高速运行。
4.可同时承受上下左右方向的负荷由于直线导轨特殊的束制结构设计,可同时承受上下左右方向的负荷,不像滑动导引在平行接触面方向可承受的侧向负荷较轻,易造成机台运行精度不良。
5.组装容易并具互换性组装时只要铣削或研磨床台上导轨之装配面,并依建议之步骤将导轨、滑块分别以特定扭力固定于机台上,即能重现加工时的高精密度。
传统的滑动导引,则须对运行轨道加以铲花,既费事又费时,且一旦机台精度不良,又必须再铲花一次。
直线导轨具有互换性,可分别更换滑块或导轨甚至是直线导轨组,机台即可重新获得高精密度的导引。

HIWIN导轨
HIWIN导轨随着现代制造技术的不断发展,使得传统的制造业发生了巨大的变化,数控技术、机电一体化和工业机器人在生产中得到了更加广泛的应用。
同时机械传动机构的定位精度、导向精度和进给速度在不断提高,使传统的导向机构发生了重大变化。
自 1973年开始商品化以来,滚动直线导轨副以其独有的特性,逐渐取代了传统的滑动HIWIN导轨,在工业生产中得到了广泛的应用。
适应了现今机械对于高精度、高速度、节约能源以及缩短产品开发周期的要求,已被广泛应用在各种重型组合加工机床、数控机床、高精度电火花切割机、磨床、工业用机器人乃至一般产业用的机械中。
滚动HIWIN导轨副的性能特点
1.定位精度高
滚动HIWIN直线导轨的运动借助钢球滚动实现,导轨副摩擦阻力小,动静摩擦阻力差值小,低速时不易产生爬行。
重复定位精度高,适合作频繁启动或换向的运动部件。
可将机床定位精度设定到超微米级。
同时根据需要,适当增加预载荷,确保钢球不发生滑动,实现平稳运动,减小了运动的冲击和振动。
2.磨损小
对于滑动导轨面的流体润滑,由于油膜的浮动,产生的运动精度误差是无法避免的。
在绝大多数情况下,流体润滑只限于边界区域,由金属接触而产生的直接摩擦是无法避免的,在这种摩擦中,大量的能量以摩擦损耗被浪费掉了。
与之相反,滚动接触由于摩擦耗能小,滚动面的摩擦损耗也相应减少,故能使滚动直线导轨系统长期处于高精度状态。
同时,由于使用润滑油也很少,这使得在机床的润滑系统设计及使用维护方面都变的非常容易。
3.适应高速运动且大幅降低驱动功率
采用滚动直线导轨的机床由于摩擦阻力小,可使所需的动力源及动力传递机构小型化,使驱动扭矩大大减少,使机床所需电力降低80%,节能效果明显。
可实现机床的高速运动,提高机床的工作效率20~30%。
4.承载能力强
滚动直线导轨副具有较好的承载性能,可以承受不同方向的力和力矩载荷,如承受上下左右方向的力,以及颠簸力矩、摇动力矩和摆动力矩。
因此,具有很好的载荷适应性。
在设计制造中加以适当的预加载荷可以增加阻尼,以提高抗振性,同时可以消除高频振动现象。
而滑动导轨在平行接触面方向可承受的侧向负荷较小,易造成机床运行精度不良。
5.组装容易并具互换性
传统的滑动导轨必须对导轨面进行刮研,既费事又费时,且一旦机床精度不良,必须再刮研一次。
滚动导轨具有互换性,只要更换滑块或导轨或整个滚动导轨副,机床即可重新获得高精度。
如前所述,由于滚珠在导轨与滑块之间的相对运动为滚动,可减少摩擦损失。
通常滚动摩擦系数为滑动摩擦系数的2%左右,因此采用滚动导轨的传动机构远优越于传统滑动导轨。
滚动直线导轨副的选用方法
滚动直线导轨副具有承载能力大、接触刚性高、可靠性高等特点,主要在机床的床身、工作台导轨和立柱上、下升降导轨上使用。
我们在选用时可以根据负荷大小,受载荷方向、冲击和振动大小等情况来选择。
1.受力方向
由于滚动直线导轨副的滑块与导轨上通常有4列圆弧滚道,因此能承受4个方向的负荷和翻转力矩。
导轨承受能力随滚道中心距增大而加大。
2.负荷大小
滚动直线导轨不同规格有着不同的承载能力,可根据承受负荷大小选择。
为使每副滚动直线导轨均有比较理想的使用寿命,可根据所选厂家提供的近似公式计算额定寿命和额定小时寿命,以便给定合理的维修和更换周期。
还要考虑滑块承受载荷后,每个滑块滚动阻力的影响,进行滚动阻力的计算,以便确定合理的驱动力。
3.预加负载的选择
根据设计结构的冲击、振动情况以及精度要求,选择合适的预压值。
滚动直线导轨副的现状
目前,国外生产滚动直线导轨副的厂商主要集中在美国、英国、德国及日本等国家。
国内在滚动直线导轨副的制造方面还处于初始阶段,与国外相比,仍有差距,主要表现为:品种少、产量小、使用寿命低,噪音大,加工工艺也不如国外先进。
以南京工艺装备制造厂、广东凯特精密机械有限公司为代表的国内企业,正在努力缩小这种差距,他们的部分产品已经具有国际先进水平。
直线滚动导轨副的发展趋势
滚动直线导轨副的新类型、新功能目前在不断涌现,并正在向组合化、集成化、高速、低噪音、智能化方向发展。
1.用滚珠保持的滚动直线导轨副
THK公司采用滚珠保持架与滚珠构成一体,保持滚珠平稳的进行循环运动,消除了滚珠间的相互摩擦,开发了噪声低、免维修、寿命长、速度可达300m/min的超高速直线运动的SSR导轨副,并已开始推广。
该导轨副实现了100m/min 运动速度下噪声小于50dB,摩擦波动幅度减少到以往产品的1/5。
另外,通过了一次加油脂2cm3,运行2800km 的试验。
今后带滚珠保持架的直线运动导轨副将逐渐成为高档数控机床选用的主流。
2.直线电动机和直线导轨并用
采用一体化直线电动机的滑台系统具有结构紧凑、运行中动力大的特点。
同时滑台系统的定位精度也有所提高。
SKF直线系统有限公司与Pratec直线电动机制造厂进行合作,并于1996年已开始推广一体化的直线电动机滑台系统产品。

4.混合工作台
日本研制了一种新型的滚动直线导轨副工作台,它具有一套滑动电磁块装置,可在定位加工时吸到导轨上以增加摩擦力,从而提高了系统的抗振性能,所以它又称为混合工作台(hybrid table system)。
5.新材料制造的滚动直线导轨副
由于用户要求的多样化及使用环境的不同,出现了用新材料制造的滚动直线导轨副。
例如,采用不锈钢制作的产品,其导轨轴、滑块、钢球、密封端和保持器均采用不锈钢材料制作,而反向器采用合成树脂,故耐腐蚀性提高。
对于要求高温和真空用途时,反向器可以采用不锈钢材。
此外,用陶瓷材料制造的滚动直线导轨副将会得到开发应用。
目前,在恶劣环境即高粉尘浓度、强酸、强碱和高腐蚀场合使用直线导轨还有一定的局限性。
但随着直线导轨技术的日益完善,以及直线导轨具有高速性与控制性等诸多突出的优点,以及丰富的类型和功能,可以预期,此机构作为一个功能部件将越来越多地用在数控机床等机械设备上。
