Linear actuator, also known as linear drive, is mainly a new type of linear actuator composed of a motor push rod and a control device. It can be considered as an extension of the rotary motor in terms of structure.
Linear actuator is an electric drive device that converts the rotary motion of the motor into the linear reciprocating motion of the push rod. It can be used as an executive machine in various simple or complex technological processes to realize remote control, centralized control or automatic control.
It is mostly used in motion drive units in household appliances, kitchen utensils, medical equipment, automobiles and other industries.
The linear actuator is composed of a drive motor, a reduction gear, a screw, a nut, a guide sleeve, a push rod, a sliding seat, a spring, a casing, a turbine, and a micro-control switch.
The linear actuator is a new type of electric actuator. The linear actuator is mainly composed of a motor, a push rod and a control device. It is a new type of linear actuator, which can realize remote control and centralized control. The electric push rod makes a reciprocating motion within a certain range of strokes. Generally, the standard stroke of the linear actuator is 100, 150, 200, 250, 300, 350, 400mm, and the special stroke can also be designed and customized according to different application conditions. Electric push rods can be designed with different thrusts according to different application loads. Generally, the maximum thrust can reach 6000N, and the no-load running speed is 4mm~35mm/s. The linear actuator is powered by a 24V/12V DC permanent magnet motor. source, which converts the rotary motion of the motor into linear reciprocating motion. Push a set of linkage mechanisms to complete the switching work of dampers, valves, gates, baffles, etc. The use of electric push rod as the actuator can not only reduce the air source device and auxiliary equipment required by the pneumatic actuator, but also reduce the weight of the actuator. Pneumatic actuators need a certain air pressure in the entire control operation process. Although amplifiers with small consumption can be used, the air consumption is still huge over time. Using electric push rod actuator, when changing the control opening, power supply is required, and no power supply is required when the required opening degree is reached. Therefore, from the perspective of energy saving, linear actuator actuators have obvious energy saving advantages over pneumatic actuators. It is suitable for long-distance operation and is widely used in the opening and closing, material loading and unloading, flow control, etc. It has been used by more and more departments to replace the automatic device of the mechanism hand, hydraulic valve and reduction transmission mechanism.
