Screw Driven Linear Modular Actuators are devices used to convert rotary motion into linear motion. Screw Driven Linear Modular Actuators consist of a motor, a screw shaft, and a nut, which are combined to create linear motion along the axis of the screw.
Here’s how a typical Screw Driven Linear Modular Actuators works:
Motor: The actuator is equipped with a motor, usually an electric motor, which provides the rotational power required for the actuator to function. The motor can be either stepper or servo motor, depending on the application requirements.
Screw Shaft: The screw shaft is a long, threaded rod that runs through the actuator. It has a helical thread that engages with the nut and converts the rotational motion of the motor into linear motion.
Nut: The nut is a component that contains a threaded hole matching the thread on the screw shaft. As the screw shaft rotates, the nut moves along the length of the shaft, causing linear displacement. The nut is usually mounted to the load or the movable part of the system.
Modular Design: The term “modular” refers to the ability to customize or configure the actuator to meet specific requirements. Screw-driven modular linear actuators are often designed with a modular structure, allowing users to choose different screw shaft lengths, motor types, and other options to suit their application needs.
Control System: The actuator is typically controlled by a control system that manages the motor’s speed, direction, and position. This control system can be as simple as an on/off switch or a more sophisticated setup using microcontrollers or programmable logic controllers (PLCs).
Screw-driven modules find applications in various industries, including robotics, automation, CNC machinery, 3D printing, medical devices, and more. They offer precise and controllable linear motion, making them suitable for applications that require accurate positioning, repetitive motion, or pushing/pulling loads.
It’s worth noting that there are different types of screw-driven actuators, including ball screw actuators and lead screw actuators. Ball screws use ball bearings to reduce friction and enhance efficiency, making them suitable for high-load and high-precision applications. Lead screws, on the other hand, have a simpler design and are often used in applications where lower precision or lower cost is acceptable.
Overall, Screw Driven Linear Modular Actuators are versatile devices that provide controlled linear motion and can be customized to meet specific application requirements.
