The tubular linear actuator is mainly composed of a drive motor, a reduction gear, a screw, a nut, a push rod, a spring, a micro-control switch, etc. Used in furniture, electronics, machinery, medical, metallurgy, transportation, petroleum, chemical, transportation, construction and other industries.

tubular linear actuator is a new type of electric actuator, its shell is heavy-duty aluminum shell, mainly composed of driving motor, reduction gear, screw, nut, guide tube, guide sleeve, push rod, mounting seat, spring, shell and worm gear. , micro-control switch, etc., the easy-to-use interface and the integrated power electronic device interface are directly connected to the control system, which can realize long-distance control and centralized control. Generally, two-stage transmission is adopted, and there are two main types of first-stage transmission deceleration. One is to use worm gear to reduce speed, and the other is to use gear to reduce speed.

Worm gear deceleration: The motor output shaft worm drives the worm gear to rotate, so that the lead screw connected in the worm gear rotates, and the nut on the lead screw moves axially in the guide tube. The motor stops running, and the forward and reverse control is the same.

Gear deceleration: After the motor is decelerated by the gear, it drives a pair of lead screw nuts, which are connected to the push rod, turning the rotary motion of the motor into the linear motion of the push rod, and using the forward and reverse rotation of the motor to complete the push rod action. Through various levers, rockers or connecting rods and other mechanisms, complex movements such as rotation and shaking can be completed.
