Automatic doors are becoming increasingly common in factories, shops, and even private residences. While they offer the advantages they should, such as ease of use and security, they also require very specific maintenance and frequently break down.
In the following article, Tengchi will analyze the different types of automatic doors on the market, their characteristics, and how to optimize them to prevent malfunctions. Different models of automatic doors are related to the reducers they use and their proper installation and correct operation. These are the different types of automatic doors currently available:
Sliding doors are operated using worm gear reducers. Their design is simple and practical because, for transmission, they only use a crown wheel meshing with the worm, thus moving the teeth and reducing the transmission speed. These reducers move in a linear fashion, meaning the gearbox can operate at 90° angles. The worm gear drive is mounted at the top of the door and transmits its motion via a pulley and belt system to achieve linear displacement.
The maintenance gate is another type of automatic gate that uses the same worm gear drive system for operation. The reducer is located at the bottom of the gate and generates motion via a pinion and rack on a motor. This allows the gate to move in a straight line.
Segmented garage doors are based on linear reducers—devices designed to convert the rotary motion of a low-voltage DC motor into linear motion. This allows the automatic door of this type to be raised, adjusted, or tilted with the touch of a button. A major advantage is that it requires less installation space compared to other systems. In this case, the linear reducer is used to close and open the swing door.
Inspection gates for shops and supermarkets
These doors are operated by planetary gear reducers, whose components are a central gear that meshes with a bracket, and a crown gear or ring gear, so the system’s central axis can be the center of rotation of the ring. This makes changing direction easy. The planetary gear reducers installed on shop and supermarket doors are concealed within tubes that secure the door to the floor, resulting in an aesthetically pleasing design. In these doors, the movement of a geared motor causes the door to move.
Do you understand how to select the right motor for your automatic door? What kind of motor will you install in your automatic door system? Feel free to leave a comment and share your thoughts!
