People who often use THK guideway in automation industry know that when THK linear guideway uses linear motion system, dust prevention is the most important factor. Why?

因為粉塵及其他異物進(jìn)入直線運動系統(tǒng)，它將導(dǎo)致異常磨損，并縮短使用壽命。這也會造成不必要的損失！所以，預(yù)計可能會有粉塵及其他異物進(jìn)入時，有必要選擇滿足使用環(huán)境條件的密封裝置進(jìn)行防塵保護(hù)。下面小編告訴大家THK直線導(dǎo)軌的防塵技巧。

Because dust and other foreign matters enter the linear motion system, it will cause abnormal wear and shorten the service life. This will also cause unnecessary losses! Therefore, it is necessary to select the sealing device to protect dust when dust and other foreign matters are expected to enter. The following small series tell you THK linear guide dust skills.

1、專用彈性護(hù)罩

1. Special elastic shield

關(guān)于THK-LM翻滾導(dǎo)軌，常常備有規(guī)范的專用彈性護(hù)罩。另外THK也制作滾珠螺桿和滾珠花鍵等其他直線運動體系的專用彈性護(hù)罩。直線運動體系有必要挑選可以滿意運用環(huán)境懇求的原料。為了可以在像易蝕性等這些苛求的環(huán)境中運用,某些直線運動體系可以運用馬氏體不銹鋼。（馬氏體不銹鋼可以運用于下列類型的 LM翻滾導(dǎo)軌∶SSR、SHW、SRS、HSR、SR、HRW、RSR、RSR-Z、RSH、RSH-Z和HR型。）直線運動體系的LM軌跡和軸的外表可以因防銹或?qū)徝乐鈭D進(jìn)行外表處置。THK供給了THK-AP處置,這是對準(zhǔn)直線運動體系的外表處置辦法。大致上有3種類型的THK-AP處置辦法∶ AP-HC、AP-C和AP-CF。

As for thk-lm rolling guide, there are usually special elastic shields. In addition, THK also makes special elastic shield for ball screw, ball spline and other linear motion systems. It is necessary for linear motion system to select raw materials which can satisfy the application environment. In order to be used in demanding environments such as erodibility, some linear motion systems can use martensitic stainless steel. (martensitic stainless steel can be used in the following types of LM rollover guides: SSR, SHW, SRS, HSR, Sr, HRW, RSR, rsr-z, RSH, rsh-z and HR.) The LM track of linear motion system and the appearance of axis can be treated for anti rust or aesthetic purpose. THK provides thk-ap treatment, which is the best way to deal with the appearance of linear motion system. Generally speaking, there are three types of thk-ap disposal methods: ap-hc, ap-c and ap-cf.

2、專用密封擋板

效果防塵密封用，在各直線導(dǎo)軌體系中備有下圖所示的高耐磨損性的特別合成橡膠制作的密封擋板（例如多層觸摸刮板LACS）和情節(jié)環(huán)等。別的，在運用環(huán)境惡劣的場所，有些類型備用專用的彈性護(hù)罩和專用防塵蓋。

In each linear guide rail system, there are sealing baffles (such as multi-layer touch scraper lacs) and rings made of special synthetic rubber with high wear resistance as shown in the figure below. In addition, some types of spare special elastic shield and special dust cover are used in places with bad operating environment.

隨著THK導(dǎo)軌的使用要求越來越嚴(yán)格苛刻，如今在其保養(yǎng)中防塵已經(jīng)成為重中之重，它比潤滑保養(yǎng)更頻繁，只要導(dǎo)軌被使用，就要隨時隨地進(jìn)行防塵保護(hù)。

Nowadays, the use of THK is more and more strict than the maintenance of dust-proof guide rail.
