线性执行器
Linear actuators are part of a motion control system that produces the desired motion. An actuator is a device that creates physical movement by converting various forms of energy to rotary or linear mechanical motion. A linear motion actuator is defined as a device that converts various forms of energy into linear motion or straight push/pull movements. Actuators (electric cylinders) are mainly thrust producing devices that use either an acme or ball screw as the driving mechanism.

我们携带的线性执行器
Rod Actuators
杆类型执行器产生更多的力，并且对肮脏的环境具有很高的耐受性，尽管它们需要轴承结构来承载载荷。当运动发生时，推力元件或杆从执行器的末端移出。
无杆执行器
在此执行器中，执行器的外壳完全围绕着螺钉，该螺钉提供了负载轴承和指导结构。无杆执行器不需要外部指南而承担载荷，特别适合在长时间长度上运输载荷。无杆无执行器很难密封，因此对于肮脏或潮湿的环境而言并不理想。
Other Types of Actuators
螺丝执行器
There are several different types of screw actuators including lead screw actuators, ball screw actuators, and planetary roller screw actuators.
铅螺钉执行器
Lead screw actuators have a threaded nut that moves with a screw, providing both simple construction and lowest cost. This type of actuator is mainly used when an industry needs a cost-effective solution. Lead screw actuators are quiet, flexible, corrosion-resistant, and have some self-locking capabilities.
Ball Screw Actuator
球螺钉执行器本质上是使用滚珠轴承的铅螺钉执行器。通常，由于其更快的速度速度和连续的占空比和承载更高负载的能力，因此选择它们。与铅螺丝执行器相比，它们更昂贵，但提供的摩擦较少。
Planetary Roller Screw Actuator
Planetary roller screw actuators are lead screw actuators that use threaded rollers surrounding the main threaded shaft. This actuator is the most expensive option, but also the most durable. Because their load-carrying rollers don’t contact each other, planetary roller screw actuators typically achieve higher speeds than ball screws.
Belt Actuators
皮带执行器是基于皮带驱动器的执行器，通常在速度很重要但准确性有限的地方使用。这些执行器以与传送带系统相同的原理运行；皮带驱动器将旋转运动转化为通过正时皮带的线性运动。皮带执行器设计用于长距离长速度的高速，非常适合快速定位和处理任务
Integrated Actuators
顾名思义，集成的执行器将杆样式执行器集成到电动机外壳中，以消除对耦合的需求。这些执行器提供最低的尺寸和重量，并更容易维护，但成本更高。

经常问的问题
什么是线性执行器？
A linear actuator is defined as a device that converts various forms of energy into linear motion or straight push/pull movements. Actuators (electric cylinders) are mainly thrust producing devices that use either an acme or ball screw as the driving mechanism. Linear actuators allow the device to slide, tilt, and lift as needed.
线性致动器如何工作？
电线线性执行器使用电能在直线上启用运动。活塞或杆根据控制信号来回移动。线性执行器使用电动机，该电动机会产生高速旋转运动和变速箱的变速箱，从而减缓其影响。这增加了用于转动铅螺钉的扭矩，从而导致轴或驱动螺母的线性运动。线性致动器通常使用12V DC电动机，但也可以使用其他电动机。将连接的极性从电动机切换到电池将使电动机沿相反方向旋转。
Why use a linear actuator?
Electric linear actuators increase efficiency and enable safe, secure, and precise motion.
How do I choose a linear actuator?
选择线性执行器时，请执行以下步骤：
- Determine the amount of force needed
- 确定执行器必须行驶的距离
- Determine the speed
- 根据您的特定项目规格和要求选择一种线性执行器
