直線導(dǎo)軌和滾珠絲桿區(qū)別很大,雖然同屬直線傳動(dòng)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(dòng)方面表現(xiàn)卻都非常出色。
There is a significant difference between linear guides and ball screws. Although they both belong to linear transmission equipment, their working principle requirements and scope of use are different. However, both have excellent performance in linear transmission.
滾珠絲杠是工具機(jī)械和精密機(jī)械上zui常使用的傳動(dòng)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(dòng)轉(zhuǎn)換成線性運(yùn)動(dòng),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)床大型設(shè)備雕刻機(jī)械等較為普遍,非常方便的把旋轉(zhuǎn)的運(yùn)動(dòng)轉(zhuǎn)換成直線運(yùn)動(dòng),用起來(lái)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 a commonly used transmission component in tool machinery and precision machinery, consisting of screw, nut, steel ball, pre press plate, reverser, dust collector. Its main function is to convert rotational motion into linear motion or torque into axial repetitive force, while also possessing high precision reversibility and high efficiency. It is mainly used for some large machine tools, equipment, carving machinery, etc. It is very convenient to convert rotary motion into linear motion, which is very convenient to use and greatly reduces the wear and tear of the entire equipment in terms of rotation.
直線導(dǎo)軌使用非常廣泛但種類很多,方型四排高珠導(dǎo)軌用于一些大型機(jī)床設(shè)備,如平面磨床,切片機(jī)線切割等;也因工作條件的不同選用的直線導(dǎo)軌也是不同的,zui適于精密測(cè)量?jī)x器半導(dǎo)體制造和檢驗(yàn)設(shè)備非標(biāo)自動(dòng)化機(jī)械設(shè)備以及其他精密直線運(yùn)動(dòng)為重要的應(yīng)用場(chǎng)合等,因不同設(shè)備需要選擇正確的導(dǎo)軌也是關(guān)重要的。
Linear guide rails are widely used but have many types. Square four row high ball guide rails are used in some large machine tools and equipment, such as surface grinders, slicers, and wire cutting; The selection of linear guides varies depending on the working conditions. They are suitable for precision measurement instruments, semiconductor manufacturing and inspection equipment, non-standard automated mechanical equipment, and other applications where precision linear motion is crucial. Choosing the correct guide is also crucial for different equipment needs.
與滑動(dòng)絲桿副相比驅(qū)動(dòng)力矩為
Compared to the sliding screw pair, the driving torque is
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(dòng)運(yùn)動(dòng),所以能得到較高的運(yùn)動(dòng)效率.與過(guò)去的滑動(dòng)絲桿副相比驅(qū)動(dòng)力矩達(dá)到1/3以下,即達(dá)到同樣運(yùn)動(dòng)結(jié)果所需的動(dòng)力為使用滾動(dòng)絲桿副的1/3.在省電方面很有幫助。
Due to the rolling motion of many balls between the screw shaft and the screw nut of the ball screw pair, high motion efficiency can be achieved. Compared with previous sliding screw pairs, the driving torque can reach less than 1/3, which requires 1/3 of the power required to achieve the same motion result when using a rolling screw pair. This is very helpful in terms of power saving.
高精度的保證
High precision assurance
滾珠絲桿副是用日本制造的世界zui高水平的機(jī)械設(shè)備連貫生產(chǎn)出來(lái)的,特別是在研削組裝檢查各工序的工廠環(huán)境方面,對(duì)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
The ball screw pair is produced continuously using world-class mechanical equipment manufactured in Japan, especially in the factory environment for grinding, assembly, and inspection of various processes. The temperature and humidity are strictly controlled, and the precision is fully guaranteed due to a sound quality management system
微進(jìn)給可能
Micro feed may
滾珠絲桿副由于是利用滾珠運(yùn)動(dòng),所以啟動(dòng)力矩ji小,不會(huì)出現(xiàn)滑動(dòng)運(yùn)動(dòng)那樣的爬行現(xiàn)象,能保證實(shí)現(xiàn)精確的微進(jìn)給
The ball screw pair utilizes ball motion, so the starting torque is small and there will be no crawling like sliding motion, ensuring accurate micro feed
無(wú)側(cè)隙剛性高
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(guò)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 subjected to preloading, which can cause the axial clearance to reach a negative value, thereby obtaining higher rigidity (in the ball screw, preloading is applied to the ball, and when used in mechanical devices, the repulsive force of the ball can enhance the rigidity of the screw head)
高速進(jìn)給可能
High speed feed may
滾珠絲桿由于運(yùn)動(dòng)效率高發(fā)熱小所以可實(shí)現(xiàn)高速進(jìn)給(運(yùn)動(dòng))。
Ball screw can achieve high-speed feed (motion) due to its high motion efficiency and low heat generation.
