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.

皮带导轨滑台和丝杆传动滑台两者之间的区别：

Differences between belt guide slide and screw drive slide:

1、滚珠丝杆传动即由电机通过联轴器或同步带轮驱动滚珠丝杆转动，进而推动固定在直线导轨上的滑块前后移动。滚珠丝杆具有定位精度高，摩擦力小，刚性高，负载能力强特点。可以实现精准的定位。

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，取决于电机的转速和丝杆导程的大小。丝杆导程越大，相同的电机输出速度下单轴机械手滑块移动的速度也越大。

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、同步齿形带传动是由电机驱动同步带的主动轮转动，进而有皮带导轨带动直线导轨上的滑块前后移动。同步齿形带具有噪音低，移动速度快，成本较低等特点。

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，一般可以实现比滚珠丝杠更高的速度。同时没有临界速度的限制，在长行程传送方面具有更加的性价比。

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.
