* The traditional linear motion form can be divided into three categories according to its principle: screw motion (electric linear actuator and servo electric cylinder); hydraulic cylinder and air cylinder. With the application of modern processing technology,the performance of the product is continuously improved, and it is more prominent than the air cylinder and hydraulic cylinder.
Electric linear transmission has the following remarkable characteristics:
* 1. Self-locking performance-ordinary gear screw electric push rods, due to the worm gear structure, most of them have absolute dynamic load self-locking function, which increases the safety of equipment operation; ball screw electric push rods and servo electric cylinders cannot be absolutely self-locking , But it can be self-locked by adding a brake to the motor;
* 2. Accuracy positioning-the comprehensive position accuracy of the servo electric cylinder can reach 0.01mm;
* 3. Precise control-configure encoder, pressure sensor, displacement sensor to realize closed loop precise positioning;
* 4. Drive system-DC motor 12/24V, single-phase AC motor, three-phase AC motor, servo motor, etc., no air/hydraulic source is needed, maintenance is simpler and more convenient, and energy consumption is low;
* 5. Overload protection-can be equipped with a safety clutch to prevent overload; it can also be equipped with an overload pressure sensor to prevent overload;
* 6. Simple maintenance-low noise, can work normally in high/low temperature, anti-corrosion/explosion-proof environment.Important features of electric linear transmission equipment: self-locking performance, precision positioning, speed control, thrust control, and easy maintenance.
