What is the working principle of electric push rod？

After being reduced by gears or worm gears, the electric motor drives a pair of screw nuts. Transform the rotational motion of the motor into linear motion, and use the forward and reverse rotation of the motor to complete the push rod action. Various mechanisms such as levers, joysticks, or linkages can be used to complete complex movements such as rotation and shaking. By changing the length of the lever arm, the stroke can be increased or decreased. Travel control device

Worm gear transmission form: The worm gear on the motor gear drives the worm gear to rotate, causing the small screw rod inside the worm gear to move axially. The connecting plate drives the limit rod to move axially accordingly. When the desired stroke is reached, the power is cut off by adjusting the limit block to press the stroke switch, and the motor stops running (with the same forward and reverse control).

Gear transmission form: The motor drives the small screw rod installed in the inner tube through the reduction gear, and drives the axial running nut connected to it. When the set stroke is reached, the nut angle presses the limit switch to disconnect the power supply, and the motor stops moving (in the opposite direction).

An optional potentiometer can be used to display the travel status of the push rod, and an encoder can also be added to achieve complete travel in several steps (i.e. start stop stop).
