The Main Structure of the Linear Actuator

Linear actuators are widely used in various fields， from robotics and medical devices to aerospace and defense, automotive, and home automation. Today’s article will take us through the main structure of the electric actuator.

The linear actuators is composed of a drive motor, a reduction gear, a screw, a nut, a guide bush, a push rod, a sliding seat, a spring, a shell and a turbine, and a micro control switch.They are a type of actuator that converts rotational motion into linear motion. Linear actuator 12v and linear actuator motor are some of the commonly used devices in these applications.The motor provides the rotational motion, which is transmitted through the gears to the screw. The screw, in turn, moves the nut along its axis, producing linear motion.

The linear actuators is a new type of electric actuator, and the electric push rod is mainly composed of a motor, a push rod and a control device, which can achieve remote control and centralized control. Linear actuators in a certain range of travel for round-trip movement, the general linear actuators standard travel in, 100,150,200,250,300,350,400 mm, special travel can also be customized according to different application conditions.

The linear actuators can be designed according to different application loads and different thrust of the electric push rod, generally its maximum thrust up to 6000N, no-load running speed of 4mm~35mm/s, the linear actuators with 24V/12V DC permanent magnet motor as the power source, the rotating motion of the motor into a linear reciprocating motion.

Push a set of linkage mechanisms to complete the switch of damper, valve, gate, baffle, etc. The use of linear actuators as the actuator can not only reduce the air supply device and auxiliary equipment required by the pneumatic actuator, but also reduce the weight of the actuator. The pneumatic actuator needs a certain air pressure during the whole control operation process, although the amplifier with small consumption can be used, but over time, the gas consumption is still huge.

The linear actuators actuator requires power supply when changing the control opening, and can no longer be powered when the required opening is reached, so from the perspective of energy saving, the linear actuators has obvious energy-saving advantages than the pneumatic actuator. Suitable for remote control and widely used in electric power, chemical, metallurgy, mining, light industry, transportation, ships and other departments of the damper, valve, gate mechanism opening and closing, material handling, flow control. It has been used by more and more departments to replace the automatic device of the mechanism hand, hydraulic valve and deceleration transmission mechanism.
