Electric push rods generally use two-stage transmission. There are mainly two types of primary transmission deceleration, one is to use worm gear for deceleration, and the other is for gear deceleration; most of the two-stage transmission uses screw nuts. Its working principle is briefly described as follows:Light hole vacuum carburizing gear for heavy duty gearbox The motor output shaft worm drives the worm wheel to rotate, which makes the screw connected in the worm wheel rotate, and the nut on the screw moves axially in the guide tube. When the required stroke is reached, the nut boss presses down the travel switch to cut off the power, and the motor stops. The positive and negative controls are the same.Heart Pacemaker Feeder Vacuum Brazing After the motor is decelerated by the gear, it drives a pair of screw nuts, and the nuts are co
