Electric cylinder motor drives a pair of screw nut electric push rod after gear deceleration, English name Linear Actuator, electric cylinder and linear actuator. The electric push rod is an electric drive device that converts the rotational motion of the motor into a linear reciprocating motion of the push rod. It can be used in a variety of simple or complex process flows to perform mechanical operations to achieve long-distance control, centralized control, or automatic control.
1, according to the form of screw: trapezoidal screw (Kangfei Ya KA10-70), ball screw type, planetary ball screw type, planetary roller screw and so on.
2, according to the type of motor: DC motor type (12/24/36V), AC motor type (220/380V), stepper motor type, servo motor type.
The electric push rod is composed of a drive motor, a reduction gear, a screw, a nut, a guide bush, a push rod, a slide, a spring, a shell and a turbine, and a micro-motion control switch.
The electric push rod is a new type of electric actuator. The electric push rod is mainly a new linear actuator composed of a motor, a push rod and a control device, and can realize remote control and centralized control. The electric push rod makes a round-trip movement within a certain range of stroke. The standard stroke of the electric push rod is generally 100, 150, 200, 250, 300, 350, 400mm. The special stroke can also be customized according to different application conditions. The electric push rod can be designed with different thrust electric push rods according to different application loads, generally its maximum thrust can reach 6000N, the no-load running speed is 4mm~35mm/s, and the electric push rod is powered by 24V/12V DC permanent magnet motor. The source converts the rotational motion of the motor into a linear reciprocating motion. Push a set of linkage mechanisms to complete the switching work of dampers, valves, gates, and baffles. The use of electric actuators as actuators not only reduces the air supply and auxiliary equipment required for pneumatic actuators, but also reduces the weight of the actuators. Pneumatic actuators require a certain amount of air pressure during the entire control operation. Although small amounts of amplifiers can be used, the air consumption is still huge. With the electric actuator actuator, when the control opening is changed, power supply is needed, and when the required opening degree is reached, the power supply can be stopped. Therefore, from the viewpoint of energy saving, the electric actuator actuator has obvious energy-saving advantages over the pneumatic actuator. It is suitable for long-distance operation and is widely used for opening and closing of dampers, valves, gates, etc. in electric power, chemical industry, metallurgy, mining, light industry, traffic, ships and other departments, material handling, and flow control. It has been used by more and more departments to replace the automatic devices of the hand, hydraulic valve, and deceleration transmission mechanism.
After the motor is decelerated by gears, it drives a pair of screw nuts. The motor's rotary motion is changed to linear motion, and the push rod motion is completed by using the forward and reverse rotation of the motor. For example, a variety of levers, rockers, or connecting rods can be used to complete complex motions such as turning and shaking. By changing the length of the lever arm, it is possible to increase or increase the stroke.
