The Difference between Belt Guide Slide and Screw Drive Slide对于带式导轨滑台与螺旋传动滑台的区别，很多用户可能难以区分。多年经验的技术工程师认为同步带传动在实际应用中定位精度低于滚珠丝杠定位精度。

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

　　带式导轨滑台与螺旋传动滑台的区别:

　　The difference between belt slide and screw drive slide:

　　滚珠丝杠传动是由电机通过联轴器或同步带轮带动滚珠丝杠转动，然后推动固定在直线导轨上的滑块前后移动。滚珠丝杠定位精度高，摩擦小，刚性高，负载大。能够完成准确定位。
                      

　　Ball screw drive is driven by a motor through a coupling or synchronous pulley to rotate the ball screw, and then push the slider fixed on the linear guide to move forward and backward. Ball screw has high positioning accuracy, low friction, high rigidity and heavy load. Accurate positioning can be achieved.

　　速度取决于电机转速和引线长度。引线越高，在电机输出速度相同的情况下，机械手滑块运动越快。

　　Speed depends on motor speed and lead length. The higher the lead wire is, the faster the slider of the manipulator moves at the same output speed of the motor.

　　2. 同步齿形带传动是由电机带动同步带的主动轮旋转，然后由皮带导轨带动直线导轨上的滑块前后移动。同步齿形带噪音小，运行速度快，成本低。

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

　　在速度方面，普通的滚珠丝杠可以达到比滚珠丝杠更高的速度。与此同时，没有临界速度限制，在长途运输中已经越来越具有成本效益。

　　In terms of speed, ordinary ball screw can achieve higher speed than ball screw. At the same time, there is no critical speed limit, which has become more and more cost-effective in long-distance transportation.
