Difference between belt guide slide and screw drive slide

1、滾珠絲桿傳動即由電機通過聯軸器或同步帶輪驅動滾珠絲桿轉動，進而推動固定在直線導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，負載能力強特點。可以實現精準的定位。

1. Ball screw drive means 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 rail to move back and forth. Ball screw has the characteristics of high positioning accuracy, low friction, high rigidity and strong load capacity. Accurate positioning can be achieved.

速度方面，取決于電機的轉速和絲桿導程的大小。絲桿導程越大，相同的電機輸出速度下單軸機械手滑塊移動的速度也越大。

In terms of speed, it depends on the speed of the motor and the lead of the screw. The larger the lead of the 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驅動同步帶的主動輪轉動，進而由皮帶導軌帶動直線導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。

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

速度方面，一般可以實現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。

In terms of speed, it can generally achieve a 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.
