滾珠絲杠的是將螺桿軸與螺母滾道內(nèi)裝進(jìn)鋼珠后進(jìn)行無限的滾動(dòng)和循環(huán)的一種機(jī)械形式,從而產(chǎn)生將旋轉(zhuǎn)運(yùn)動(dòng)轉(zhuǎn)化為直線定位運(yùn)動(dòng)。為減少鋼珠在滾道內(nèi)循環(huán)時(shí)產(chǎn)生的摩擦力矩,把絲桿和螺母滾道與鋼珠的線接觸設(shè)計(jì)成點(diǎn)接觸結(jié)構(gòu)。
Ball screw is a mechanical form of infinite rolling and circulation after installing steel balls into the screw shaft and nut raceway, so as to convert the rotating motion into linear positioning motion. In order to reduce the friction torque generated when the steel ball circulates in the raceway, the linear contact between the screw rod and nut raceway and the steel ball is designed as a point contact structure.
知識(shí)點(diǎn)!滾珠絲杠和普通絲杠的區(qū)別在哪里?
Knowledge point! What is the difference between ball screw and ordinary screw?
自鎖性:自鎖性一般與傳統(tǒng)效率成反比,傳動(dòng)效率越高,自鎖性就越小,因此,滾珠絲杠幾乎沒有自鎖性,而普通絲杠(即梯形絲杠)具有一定的自鎖性。
Self locking: self locking is generally inversely proportional to the traditional efficiency. The higher the transmission efficiency, the smaller the self-locking. Therefore, the ball screw has almost no self-locking, while the ordinary screw (i.e. trapezoidal screw) has a certain self-locking.
經(jīng)濟(jì)性:從以前和目前的情況來看,滾珠絲杠因其結(jié)構(gòu)較梯形復(fù)雜,仍然比梯形絲杠高。不過,隨著自動(dòng)化設(shè)備的增多而產(chǎn)量大,差異越來越小。
Economy: from the previous and current situation, the price of ball screw is still higher than that of trapezoidal screw because its structure is more trapezoidal and complex. However, with the increase of automation equipment and large output, the price difference is becoming smaller and smaller.
傳動(dòng)速度:滾珠絲杠是滾動(dòng)摩擦,梯形絲杠是滑動(dòng)摩擦,工作時(shí)前者的溫升遠(yuǎn)低于后者,因此可以承擔(dān)高速傳動(dòng)任務(wù)。
Transmission speed: the ball screw is rolling friction and the trapezoidal screw is sliding friction. When working, the temperature rise of the former is much lower than that of the latter, so it can undertake the task of high-speed transmission.
使用壽命:滾動(dòng)摩擦的表面損傷比滑動(dòng)摩擦的小很多,因此在清潔、潤(rùn)滑等條件符合時(shí),滾珠絲杠的維持壽命比梯形絲杠高得多。
Service life: the surface damage of rolling friction is much smaller than that of sliding friction. Therefore, when the cleaning, lubrication and other conditions are met, the maintenance life of ball screw is much higher than that of trapezoidal screw.

傳動(dòng)效率:滾珠絲杠由于滾動(dòng)絲杠副的絲杠軸與絲杠螺母之間有很多滾珠在做滾動(dòng)運(yùn)動(dòng),所以運(yùn)動(dòng)效率高。
Transmission efficiency: the ball screw has high movement efficiency because there are many balls rolling between the screw shaft of the rolling screw pair and the screw nut.
