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.

滾珠絲杠驅動執行機構：滾珠絲杠驅動執行機構背后的基本原理實質上是對絲杠驅動系統的改進。滾珠絲杠驅動執行機構中，滾珠絲杠的旋轉驅動滾珠螺母/安裝支架，因為接口是螺柱和滾珠絲杠之間基本上是一個滾珠軸承系統，螺母中的硬化鋼球沿著螺柱的滾道滾動。與皮帶驅動執行機構類似，滾珠絲杠驅動執行機構的驅動部件封閉在鋁體內，而機架在頂部移動。與皮帶驅動執行器不同，驅動軸接口與滾珠絲杠對齊，位于執行器末端。

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.

各自的優勢和局限性：

Respective advantages and limitations:

對于需要長行程的應用，通常皮帶驅動模組導軌機構，這比使用類似長度的滾珠絲杠驅動執行機構更具成本效益。MJUNIT邁捷關鍵運動部件，從而減少勞動密集型維護。盡管如此，為了確保扭矩的正確傳遞，皮帶的適當張力關重要，通常需要在定期維護期間重新張緊皮帶。

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，滾珠絲杠裝置與滾動滾珠軸承系統非常相似，因此能夠承載更高的負載并獲得更高的推力。因此，滾珠絲杠驅動執行機構在可能需要定位大型、重型負載的應用中是理想的。達到高精度。根據具體的執行機構設計，可能需要定期潤滑滾珠絲杠。

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.
