For the difference between belt guide slide and screw drive slide, it may be difficult for many users to distinguish. Technical engineers with many years of experience think that the positioning accuracy of synchronous belt drive is lower than that of ball screw drive in practical application.

皮帶導(dǎo)軌滑臺和絲桿傳動滑臺兩者之間的區(qū)別：

Differences between belt guide slide and screw drive slide:

1、滾珠絲桿傳動即由電機(jī)通過聯(lián)軸器或同步帶輪驅(qū)動滾珠絲桿轉(zhuǎn)動，進(jìn)而推動固定在直線導(dǎo)軌上的滑塊前后移動。滾珠絲桿具有定位精度高，摩擦力小，剛性高，負(fù)載能力強(qiáng)特點(diǎn)。可以實(shí)現(xiàn)精準(zhǔn)的定位。

1. Ball screw drive is that the motor drives the ball screw to rotate through the coupling or synchronous pulley, and then pushes the slider fixed on the linear guide to move back and forth. The ball screw has the characteristics of high positioning accuracy, small friction, high rigidity and strong load capacity. Accurate positioning can be achieved.

速度方面，取決于電機(jī)的轉(zhuǎn)速和絲桿導(dǎo)程的大小。絲桿導(dǎo)程越大，相同的電機(jī)輸出速度下單軸機(jī)械手滑塊移動的速度也越大。

Speed, depends on the speed of the motor and the size of the lead screw. The larger the lead of the lead screw, the faster the slider of the single axis manipulator moves at the same motor output speed.

2、同步齒形帶傳動是由電機(jī)驅(qū)動同步帶的主動輪轉(zhuǎn)動，進(jìn)而有皮帶導(dǎo)軌帶動直線導(dǎo)軌上的滑塊前后移動。同步齒形帶具有噪音低，移動速度快，成本較低等特點(diǎn)。

2. The synchronous toothed belt drive is driven by the motor, the driving wheel of the synchronous belt rotates, and the belt guide rail drives the slider on the linear guide rail to move back and forth. Synchronous toothed belt has the characteristics of low noise, fast moving speed and low cost.

速度方面，一般可以實(shí)現(xiàn)比滾珠絲杠更高的速度。同時沒有臨界速度的限制，在長行程傳送方面具有更加的性價比。

Speed, generally can achieve higher speed than the ball screw. At the same time, there is no limit of critical speed, so it has more cost-effective in long-distance transmission.
