The challenge for mechanical automation systems is to successfully transform rotary motion from a motor or mechanical motor into a useful linear motion form. A breakthrough in this area, the conveyor belt system represents the conversion of rotation to linear motion used in production environments. These systems can transport various raw materials and workpieces in a more useful way than before using mechanical force, and can be used in a very useful production environment.

今天，在旋转运动转换领域的重要工程工作已经产生了各种各样的线性机械执行器，这些执行器对广泛的自动化应用非常有用。挑战在于为所需的功能选择合适的执行器，无论它是意味着原材料在制造环境中的移动，或更的运动系统的构造，旨在将模具移动到精确的位置。

Today, important engineering work in the field of rotary motion conversion has produced a variety of linear mechanical actuators, which are very useful for a wide range of advanced automation applications. The challenge is to select the appropriate actuator for the required function, whether it means the movement of raw materials in the manufacturing environment or the construction of more advanced motion systems, aimed at moving the mold to a precise position.

为了选择合适的线性机械执行机构，需要考虑一些重要的考虑因素，如所需的负载能力或推力以及必要的行程距离。虽然这些是主要考虑因素，但其他因素，如维护负担，无疑起着重要作用。同样重要的角色。

In order to select a suitable linear mechanical actuator, some important considerations need to be considered, such as the required load capacity or thrust and the necessary travel distance. Although these are the main considerations, other factors, such as the maintenance burden, undoubtedly play an important role. An equally important role.

两种广泛使用的机械化线性执行器因其驱动机制而有所不同-皮带驱动和滚珠丝杠驱动执行器。这两种类型在类似的应用中都被采用，但两种类型在功能上有显着差异。每种类型都具有独特的强度和重要限制，在选择执行机构时需要仔细考虑这些限制。

The two widely used mechanized linear actuators differ depending on their driving mechanisms - belt driven and ball screw driven. Both types are used in similar applications, but there are significant differences in functions between the two types. Each type has unique strengths and important limitations that need to be carefully considered when selecting an actuator.

同步带模组导轨：带传动执行机构的工作原理与输送带系统相同。带传动通过连接在两个环形滑轮之间的正时皮带将旋转运动转换为线性运动。正时皮带通常由纤维增强弹性材料制成。奥默，但许多其他的皮带材料可用于更苛刻的应用。皮带包含与转子皮带轮连接的齿，以有用地传递扭矩和防止打滑。皮带传动被封闭在铝体内，而滑块位于顶部，驱动轴接口通常垂直于执行机构的侧面。

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 through a timing belt connected between two circular pulleys. The timing belt is usually made of fiber reinforced elastic material. Omer, but many other belt materials can be used 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 aluminum, while the slider is 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 the improvement of the lead screw drive system. In the ball screw drive actuator, the rotation of the ball screw drives the ball nut/mounting bracket. Because the interface between the stud and the ball screw is basically a ball bearing system, the hardened steel ball in the nut rolls along the raceway of the stud. Similar to the belt driven actuator, the drive part of the ball screw driven actuator is enclosed in the aluminum body, while the rack moves at the top. Unlike belt drive actuators, the drive shaft interface is aligned with the ball screw at the end of the actuator.

各自的优势和局限性：

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, it is usually more cost-effective to drive the guide mechanism of the module with a belt than to drive the actuator with a ball screw of similar length. MJUNIT takes advantage of key moving parts to reduce labor-intensive maintenance. However, in order to ensure the correct transmission of torque, the proper tension of the belt is essential 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。

Or, the ball screw device is very similar to the rolling ball bearing system, so it can carry higher loads and obtain higher thrust. Therefore, ball screw driven actuators are ideal for applications where large, heavy loads may need to be located. Achieve high accuracy. Depending on the specific actuator design, it may be necessary to lubricate the ball screw regularly.

两种执行器类型之间的进一步比较揭示了皮带驱动执行器的其他缺点，尽管其简单。对于更高的负载/推力需求，需要更厚的皮带。皮带也容易受到冲击负载的影响，尽管这一问题可能是通过对皮带材料的精心选择，在一定程度上减轻了皮带的弹性，增加了强度。另外，由于皮带容易伸长，滚珠丝杠执行机构的定位精度往往优于皮带驱动执行机构。正因为如此，滚珠丝杠驱动执行机构更适合于在长时间内要求高可靠性和重复性的应用。滚珠丝杠驱动执行机构是高加速度和高推力要求的选择，因为在这种重复要求下，皮带传动皮带轮很容易在转子处滑动。

A further comparison between the two actuator types reveals other disadvantages of belt driven actuators, despite their simplicity. For higher load/thrust demands, thicker belts are required. The belt is also vulnerable to impact load, although this problem may be due to careful selection of belt materials, which to some extent reduces the elasticity of the belt and increases the strength. In addition, because the belt is easy to stretch, the positioning accuracy of the ball screw actuator is often better than that of the belt driven actuator. Because of this, the ball screw driven actuator is more suitable for applications requiring high reliability and repeatability for a long time. The ball screw drive actuator is the choice for high acceleration and high thrust requirements, because under such repeated requirements, the belt drive pulley is easy to slide at the rotor.

综上所述，滚珠丝杠驱动执行机构在需要高负载和/或推力以及高精度定位的应用中是更好的选择。然而，由于其简单，对于负载较低的应用，尤其是需要更高速度的应用，皮带驱动执行机构仍然是更好的选择。对于长行程应用，皮带驱动执行机构也可以是一种经济有用的解决方案。尽管在皮带驱动和滚珠丝杠驱动的机械执行机构之间进行选择的任务可能令人望而生畏。乍一看，每个设计的优点和缺点为每个独特的应用提供了明确的选择。

To sum up, the ball screw driven actuator is a better choice in applications requiring high load and/or thrust and high-precision positioning. However, due to its simplicity, belt driven actuators are still a better choice for applications with lower loads, especially those requiring higher speeds. Belt driven actuators can also be a cost-effective solution for long stroke applications. Although the task of choosing between belt driven and ball screw driven mechanical actuators can be daunting. At first glance, the advantages and disadvantages of each design provide a clear choice for each unique application.
