Linear Actuators
线性致动器是一个运动控制系统的一部分em 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.

Linear Actuators we Carry
Rod Actuators
Rod type actuators produce more force and are highly tolerant of dirty environments, although they require a bearing structure to carry the load. The thrust element or rod moves out of the end of the actuator as motion takes place.
无杆执行器
In this actuator, the actuator housing completely surrounds the screw, which provides a load bearing and guidance structure. Rodless actuators carry the load without the need for external guides and are particularly suited for transporting loads at long stroke lengths. Rodless actuators are difficult to seal and thus are not ideal for dirty or wet environments.
Other Types of Actuators
螺丝执行器
有几种不同类型的螺丝执行器，包括铅螺钉执行器，球螺钉执行器和行星辊螺丝执行器。
Lead Screw Actuator
铅螺钉执行器具有螺纹螺母，可用螺钉移动，提供简单的结构和最低的成本。当行业需要具有成本效益的解决方案时，主要使用这种执行器。铅螺丝执行器是安静，柔性，耐腐蚀的，并且具有一些自锁定能力。
球螺钉执行器
Ball screw actuators are essentially lead screw actuators that use ball bearings. They are usually chosen due to their faster rates of speed with continuous duty cycles and ability to carry higher loads. They are more expensive but offer less friction when compared to lead screw actuators.
Planetary Roller Screw Actuator
行星辊螺钉执行器是铅螺钉执行器，使用主螺纹轴周围的螺纹滚筒。该执行器是最昂贵的选择，但也是最耐用的选择。由于他们的载荷滚筒不会相互接触，因此行星辊螺钉执行器通常比球螺钉更高的速度。
Belt Actuators
Belt actuators are actuators based on belt drives and are often used where speed is important but with limited accuracy. These actuators operate under the same principle as the conveyor belt system; the belt drive translates rotary motion to linear motion via a timing belt. Belt actuators are designed for high speeds with long distances and are perfect for fast positioning and handling tasks
Integrated Actuators
Integrated actuators, as the name suggests, integrate a rod style actuator into a motor housing to eliminate the need for coupling. These actuators provide the lowest size and weight with easier maintenance, but at a higher cost.

Frequently Asked Questions
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.
How do linear actuators work?
电线性执行器使用电能来使运动在直线中。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，从而减慢其影响。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。
