Electric push rod, English name is linear actuator, also known as push rod motor, electric cylinder and linear actuator. The electric push rod is a kind of electric driving device which transforms the rotary motion of the motor into the linear reciprocating motion of the push rod. It can be used in a variety of simple or complex process flow as executive machinery to achieve remote control, centralized control or automatic control.


2. Principle and structure of electric push rod
The electric push rod is a new type of electric actuator, which is mainly composed of drive motor, reduction gear, screw, nut, guide sleeve, push rod, sliding seat, spring, shell, turbine, micro control switch and other mechanisms, which can realize remote control and centralized control.




3. Principle of electric push rod
The electric push rod is a kind of electric driving device which transforms the rotary motion of the motor into the linear reciprocating motion of the push rod, Its principle is: after the motor is decelerated by gears, it drives a pair of screw nuts to turn the rotary motion of the motor into a linear motion. The push rod action is completed by using the positive and reverse rotation of the motor. For example, the complex actions such as rotation and shaking can be completed through various mechanisms such as lever, rocker or connecting rod. The stroke can be increased or increased by changing the length of lever arm.
