They are convenient and stable to install and use. They are a mechanism responsible for opening and closing the elevator hall car door. When they receive the elevator door opening and closing signals, the elevator door machine controls the door opening motor through its own control system, converts the torque generated by the motor into a force in a specific direction, closes or opens the door, and is convenient for protective use to achieve a certain opening and closing effect.

[0003] The circular door machine is a type of elevator door machine, which is often used in supermarkets and sightseeing elevators in some scenic spots. The circular door machine is mainly composed of a car top assembly, a car door assembly, and a bottom support assembly, and the car door assembly is mainly used to control the opening and closing of the car door. For the circular door machine, because the car door opens and closes in an arc, if the traditional gear drive is used, the power loss during the transmission process is large. At the same time, after long-term use, it is very easy to generate friction noise due to factors such as dust accumulation, thereby reducing the comfort of passengers. Utility Model Content
