確切地說(shuō),當(dāng)需要對(duì)直線滑軌進(jìn)行花鍵時(shí),關(guān)節(jié)操作的間隙不應(yīng)超過(guò)所使用鋼球直徑的1/3,并應(yīng)盡量減小差值。一般情況下,直切界面可直切;特殊點(diǎn)需采用凹凸、t型接口端面。
To be exact, when it is necessary to spline the straight rail, the clearance of joint operation shall not exceed 1 / 3 of the diameter of steel ball used, and the difference shall be minimized. In general, the straight cutting interface can be straight cut; special points need to use concave convex, T-shaped interface end face.
安裝拼接式直線導(dǎo)軌時(shí),應(yīng)特別注意安裝面平行度:
When installing the splicing linear guide rail, pay special attention to the parallelism of the installation surface:
1. 保證基礎(chǔ)安裝基準(zhǔn)和橫向基準(zhǔn)的平直度。對(duì)接后高度差越小越好。

1. Ensure the straightness of foundation installation datum and transverse datum. The smaller the height difference after docking, the better.
2. 將導(dǎo)軌固定在底座上時(shí),擰緊安裝螺絲,以保證連接處間隙小,上下左右兩側(cè)無(wú)錯(cuò)位。然后完全鎖定安裝螺絲。
2. When fixing the guide rail on the base, tighten the mounting screws to ensure that the gap at the connection is small and there is no dislocation at the left and right sides. Then fully lock the mounting screws.
3、以一導(dǎo)軌安裝為基準(zhǔn),第二表安裝,保證兩導(dǎo)軌平行。注意不要弄斷導(dǎo)軌的端面,否則滑塊將不能平穩(wěn)運(yùn)行市場(chǎng)上常用的直線導(dǎo)軌有:矩形、三角形、燕尾形和圓柱形等。
3. Based on the installation of the first guide rail, the second table is installed to ensure that the two guide rails are parallel. Pay attention not to break the end face of the guide rail, otherwise the slider will not run smoothly. The common linear guide rails on the market are: rectangle, triangle, dovetail, cylinder, etc.
矩形導(dǎo)軌分為凹型和凸型兩種,兩種形狀的直線導(dǎo)軌可以相互組合。凸導(dǎo)軌不容易積存潤(rùn)滑油,當(dāng)然也不容易積存較多的雜物和污垢,所以多用于低速運(yùn)動(dòng)和不易保護(hù)的部位;凹面導(dǎo)軌正好相反,所以凹面導(dǎo)軌是用來(lái)移動(dòng)較快的零件,但必須有防屑保護(hù)裝置。
The rectangular guide rail can be divided into concave type and convex type. The linear guide rail with two shapes can be combined with each other. Convex guide rail is not easy to accumulate lubricating oil, of course, it is not easy to accumulate more debris and dirt, so it is mostly used for low-speed movement and parts that are not easy to protect; concave guide rail is just the opposite, so concave guide rail is used for moving faster parts, but it must have anti chip protection device.
由于三角導(dǎo)軌依靠其兩側(cè)導(dǎo)軌,所以磨損可以自動(dòng)補(bǔ)償,所以其導(dǎo)向精度高。導(dǎo)向精度隨頂角的增大而減小。軸承面積隨著頂角的增大而增大。頂角通常是900度;在受力較大的機(jī)械系統(tǒng)中,頂角為110 ~ 1200。對(duì)于精度較高的機(jī)械系統(tǒng),頂角通常小于90度,因此三角導(dǎo)軌的加工、檢測(cè)和維護(hù)比較困難。
Because the triangular guide depends on the guide rails on both sides, the wear can be compensated automatically, so its guide precision is high. The guidance accuracy decreases with the increase of the vertex angle. The bearing area increases with the increase of top angle. The top angle is usually 900 degrees; in mechanical systems with large forces, the top angle is 110 ~ 1200. For the mechanical system with high precision, the top angle is usually less than 90 degrees, so it is difficult to process, detect and maintain the triangular guide rail.
矩形導(dǎo)軌剛度和承載能力大,等效摩擦系數(shù)低于三角形導(dǎo)軌。制造、調(diào)整、檢查、維修都很方便,但經(jīng)過(guò)側(cè)面磨損后不能自動(dòng)補(bǔ)償,所以必須有間隙調(diào)整裝置。
The stiffness and bearing capacity of rectangular guide rail are large, and the equivalent friction coefficient is lower than that of triangular guide rail. It is very convenient to manufacture, adjust, check and maintain, but it can't compensate automatically after side wear, so there must be a gap adjustment device.
線性導(dǎo)軌能承受傾覆力矩,可用于調(diào)節(jié)水平和垂直間隙。這種直線導(dǎo)軌剛性較差,摩擦、制造、檢驗(yàn)、維修都比較復(fù)雜。一般主要用于運(yùn)動(dòng)件的多層,受力小,間隙調(diào)整方便。
Linear guide rail can bear overturning moment, and can be used to adjust horizontal and vertical clearance. The rigidity of this kind of linear guide rail is poor, and its friction, manufacture, inspection and maintenance are complex. Generally, it is mainly used for multi-layer moving parts, with small stress and convenient clearance adjustment.
