Dust-proof is a key measure for linear guide to obtain good machining accuracy and maintain its performance characteristics. For such components with high precision requirements, any dust and impurities are not good. It will destroy the whole linear motion system and shorten the service life. Then, how should we do well in the dust prevention work of linear guides?

，直線導(dǎo)軌系統(tǒng)里面離不開(kāi)密封件的使用，因?yàn)樗胁簧俚目p隙比較容易讓灰塵和雜質(zhì)鉆空子，所以要想讓整個(gè)系統(tǒng)內(nèi)部達(dá)到一個(gè)密封的狀態(tài)就必須要用密封墊片將這些縫隙給堵上。

Firstly, the use of seals is indispensable to the linear guideway system, because it has many cracks which are easy to let dust and impurities drill holes, so in order to make the whole system to achieve a sealed state, it is necessary to use sealing gaskets to plug these cracks.

但是對(duì)于密封墊片的使用是有一些講究的，它不是普通的材料就可以，相反，用于制作直線導(dǎo)軌密封墊片的材料必須是的橡膠材料，然后制作成清潔環(huán)。

But for the use of sealing gaskets, there are some fastidious, it is not ordinary material can, on the contrary, used to make linear guide sealing gaskets material must be professional rubber material, and then made into a clean ring.

橡膠墊片較大的好處就在于它具有非常強(qiáng)的韌性，彈性系數(shù)非常高，雖然它的制作成本比普通的塑料墊片高了很多，但是它作為墊片使用的時(shí)候可以不留半點(diǎn)縫隙。

The greatest advantage of rubber gasket is that it has very strong toughness and high elastic coefficient. Although its production cost is much higher than that of ordinary plastic gasket, it can be used as gasket without leaving half a gap.

其次，防塵罩的使用對(duì)防塵也有很好的效果，現(xiàn)在使用的防塵罩有專(zhuān)門(mén)針對(duì)惡劣環(huán)境和普通的工作環(huán)境兩種。在惡劣環(huán)境下使用的防塵罩柔軟性是非常好的，它可以自由的伸縮，這樣就能應(yīng)對(duì)不同的機(jī)床結(jié)構(gòu)。還有一種是防塵器，它主要是防止灰塵接近直線導(dǎo)軌。

Secondly, the use of dust-proof cover also has a good effect on dust-proof. The dust-proof cover used now has two kinds of special for harsh environment and ordinary working environment. The dustproof cover used in harsh environment is very flexible, it can be flexible freely, so that it can cope with different machine tool structures. There is also a professional dustproof device, which mainly prevents dust from approaching linear guides.

較后，如果需要對(duì)直線導(dǎo)軌的滾珠絲桿提供防塵保護(hù)的話，還可以使用大型的伸縮防塵罩。

Finally, if it is necessary to provide dust-proof protection for ball screw of linear guideway, large-scale retractable dust-proof cover can also be used.

 

 

直線導(dǎo)軌的磨損

Wear of linear guides

直線導(dǎo)軌發(fā)生磨損，將會(huì)導(dǎo)致導(dǎo)軌失效，必須更換新的直線導(dǎo)軌，否則將會(huì)嚴(yán)重影響到機(jī)械設(shè)備的生產(chǎn)效率，更有甚者會(huì)造成設(shè)備的損壞。所以我們?cè)谌粘５墓ぷ髦?，?yīng)當(dāng)仔細(xì)分析直線導(dǎo)軌產(chǎn)生磨損的各種原因，這樣才能找到針對(duì)直線導(dǎo)軌的磨損解決方案。

The wear and tear of linear guides will lead to the failure of the guides. It is necessary to replace the new linear guides. Otherwise, it will seriously affect the production efficiency of mechanical equipment, or even cause damage to the equipment. Therefore, in our daily work, we should carefully analyze the causes of wear and tear of linear guides, so as to find a solution for wear and tear of linear guides.

1、當(dāng)有異物進(jìn)入到了密封不嚴(yán)的直線導(dǎo)軌內(nèi)部后，將會(huì)與潤(rùn)滑油混合在一起，從而造成滑塊內(nèi)部溝槽堵塞，或者直接對(duì)直線導(dǎo)軌內(nèi)部造成損傷。

1. When a foreign body enters the improperly sealed linear guide, it will be mixed with lubricating oil, which will result in the blockage of the grooves in the slider, or directly cause damage to the internal of the linear guide.

2、如果潤(rùn)滑油里面的雜質(zhì)沒(méi)有過(guò)濾干凈，有雜質(zhì)混入導(dǎo)軌內(nèi)部，或者潤(rùn)滑的方式不良、選用的潤(rùn)滑劑不正確或變質(zhì)都會(huì)造成直線導(dǎo)軌的磨損。

2. If the impurities in the lubricating oil are not filtered, impurities are mixed into the guide rail, or the lubrication method is not good, the selected lubricant is incorrect or deteriorated, it will cause the wear and tear of the linear guide rail.

3、直線導(dǎo)軌使用時(shí)因?yàn)闇囟茸兓a(chǎn)生的冷凝水或是潤(rùn)滑劑中添加劑的腐蝕性物質(zhì)也會(huì)造成導(dǎo)軌滑塊的銹蝕，從而造成磨損。

3. Condensate water or corrosive substances of additives in lubricants caused by temperature change will also cause the rust of slider of linear guideway, which will cause wear and tear.

以上這些異常將會(huì)引起直線導(dǎo)軌工作表面的粗糙和游隙的增加，較終導(dǎo)致導(dǎo)軌的失效。由此可見(jiàn)只要是金屬零件，它的正常磨損是不可避免的，而且正常磨損是均勻并且緩慢的進(jìn)行的，它的磨損程度以及磨損的時(shí)間我們也可以按照規(guī)律進(jìn)行預(yù)料。

These abnormalities will cause the roughness of the working surface and the increase of the clearance of the linear guide, and eventually lead to the failure of the guide. Therefore, as long as it is a metal part, its normal wear is inevitable, and the normal wear is uniform and slow, its wear degree and wear time can also be predicted according to the law.
