What is the working principle of gsh10 linear actuator?

gsh10 linear actuator is a device capable of achieving linear motion. It is typically used in automated equipment, precision measuring instruments, and applications that require precise position control. Its working principle is based on converting the rotational motion of the motor into the linear motion of the slider (stage). The following are the basic components and working principle of the gsh10 linear actuator:

Components

Drive motor: Stepper motors or servo motors are usually used as the drive source because they can provide precise position control.

Transmission mechanisms: Common ones include ball screws, belts or rack and pinion gears, etc. Among them, ball screws are widely used due to their high efficiency, high precision and long service life.

Guide rails and sliders: Ensure that the slide table moves smoothly along the predetermined path, reduce frictional resistance, and improve motion accuracy.

Control system: It includes a controller and a driver, which are used to send instructions to the motor to achieve the required motion parameters such as speed, acceleration, and position.

Working principle

When the motor receives the signal sent by the control system, it starts to operate and directly or indirectly drives the transmission mechanism through the coupling.

For instance, in the case of using a ball screw, the rotational motion of the motor causes the screw to rotate, which in turn drives the nut (connected to the slider) to move in a straight line along the screw. Due to the design of the ball screw, the friction between the rolling elements (steel balls) is greatly reduced, which makes the energy transmission efficiency higher and at the same time improves the positioning accuracy and repeatability.

The guide rail ensures the stability and directional accuracy of the slider during movement, enabling it to move in a straight line along the preset trajectory.

The control system adjusts the motor's movement in real time based on the feedback mechanism (if any), such as the position information provided by the encoder, to ensure the accuracy of reaching the final target position.

In conclusion, the core working principle of the gsh10 linear actuator lies in converting the rotational motion generated by the motor into linear motion through a specific mechanical structure, and relying on the control system to achieve highly precise control of this process.
