Synchronous belt module guide rail: the working principle of the belt drive actuator is the same as that of the conveyor belt system. The belt drive converts rotary motion into linear motion by means of a timing belt connected between two annular pulleys. The timing belt is usually made of fiber reinforced elastic material. Omer, however, many other belt materials are available for more demanding applications. The belt contains teeth connected to the rotor pulley to effectively transmit torque and prevent slipping. The belt drive is enclosed in an aluminum body with the slider at the top, and the drive shaft interface is usually perpendicular to the side of the actuator.

滚珠丝杠驱动执行机构：滚珠丝杠驱动执行机构背后的基本原理实质上是对丝杠驱动系统的改进。滚珠丝杠驱动执行机构中，滚珠丝杠的旋转驱动滚珠螺母/安装支架，因为接口是螺柱和滚珠丝杠之间基本上是一个滚珠轴承系统，螺母中的硬化钢球沿着螺柱的滚道滚动。与皮带驱动执行机构类似，滚珠丝杠驱动执行机构的驱动部件封闭在铝体内，而机架在顶部移动。与皮带驱动执行器不同，驱动轴接口与滚珠丝杠对齐，位于执行器末端。

Ball screw drive actuator: the basic principle behind the ball screw drive actuator is essentially an improvement of the screw drive system. In the ball screw drive actuator, the rotation of the ball screw drives the ball nut / mounting bracket, because the interface is basically a ball bearing system between the stud and the ball screw, and the hardened steel balls in the nut roll along the raceway of the stud. Similar to the belt driven actuator, the driving part of the ball screw driven actuator is enclosed in the aluminum body, while the frame moves on top. Unlike belt driven actuators, the drive shaft interface is aligned with the ball screw and is located at the end of the actuator.

各自的优势和局限性：

Respective advantages and limitations:

对于需要长行程的应用，通常皮带驱动模组导轨机构，这比使用类似长度的滚珠丝杠驱动执行机构更具成本效益。MJUNIT迈捷关键运动部件，从而减少劳动密集型维护。尽管如此，为了确保扭矩的正确传递，皮带的适当张力关重要，通常需要在定期维护期间重新张紧皮带。

For applications requiring long stroke, belt driven module guide mechanisms are usually preferred, which is more cost-effective than using ball screws of similar length to drive actuators. Mjunit is a key moving part of maijie, thus reducing labor-intensive maintenance. However, in order to ensure the correct transmission of torque, the proper tension of the belt is very important, and it is usually necessary to re tension the belt during regular maintenance.

或者，滚珠丝杠装置与滚动滚珠轴承系统非常相似，因此能够承载更高的负载并获得更高的推力。因此，滚珠丝杠驱动执行机构在可能需要定位大型、重型负载的应用中是理想的。达到高精度。根据具体的执行机构设计，可能需要定期润滑滚珠丝杠。

Alternatively, the ball screw unit is very similar to the rolling ball bearing system, so it can carry higher load and obtain higher thrust. Therefore, ball screw driven actuators are ideal for applications that may require positioning large, heavy loads. Achieve high accuracy. Depending on the specific actuator design, it may be necessary to lubricate the ball screws regularly.
