Working principle of electric cylinder, internal structure diagram of electric cylinder

Electric cylinders have many names, such as servo electric cylinders, electric actuators, electric slides... The function of electric cylinders is to convert the rotational power of servo motors into linear motion. Because of this function, electric cylinders are widely used in experiments Equipment, military equipment, medical equipment... Next, follow the electric cylinder manufacturer to take a look at the internal structure diagram of the electric cylinder and the working principle of the electric cylinder.





Internal structure diagram of electric cylinder


The structure of the electric cylinder is simply divided into: screw rod, cylinder block, motor and power tube. All electric cylinders currently on the market are the same. Let's take a look at the structures of different types of electric cylinders.

The internal structure diagram of domestic electric cylinders is generally divided into the following three types:





1. Servo motor, double tail lug, ball screw, cylinder block, linear displacement sensor, front end cover, rod end double tail lug.








2. Pulley cover, rear bottom plate, bearing seat, lower limit switch, cylinder block, upper limit switch, front flange, piston rod, front end cover, servo motor, planetary reducer.








3. Servo motor, side flange, bearing seat, cylinder block, grating ruler, piston rod.





Internal structure diagram of heavy-duty electric cylinder





Manual axle, motor, brake, spring assembly, frame, lead screw, top clamp, rod.





Internal structure diagram of high-performance electric cylinder





Servo motor, planetary reducer, synchronous belt box, synchronous belt, roller nut, electric cylinder block, power tube.





Working principle of electric cylinder


The working principle of the electric cylinder is to use electricity as the direct power source, using various types of motors (such as AC servo motors, stepper servo motors, DC servo motors) to drive different forms of lead screws (or nuts) to rotate, and pass between the components. The spiral motion is converted into the linear motion of the nut (or screw), and then the nut (or screw) drives the cylinder or load to make reciprocating linear motion. Traditional electric cylinders generally use an electric motor to drive the screw to rotate, and convert the spiral motion between components into linear motion of the nut. The "nut reversal type" electric cylinders that have emerged in recent years (such as integral planetary roller screw electric cylinders) use the opposite driving method, that is, the drive nut rotates and is converted into linear motion of the screw through the spiral motion between the components. .
