The ferris wheel is a large wheel-shaped mechanical building facility. Hanging on the edge of the wheel is a passenger cabin (Gondola). Passengers sit on the Ferris wheel and turn up slowly, they can overlook the surroundings from a height. The most common occasions where the Ferris Wheel exists are amusement parks (or theme parks) and garden games. As a kind of playground mobile game, they are collectively called “Three Treasures of Paradise” with roller coasters and carousels. But the Ferris wheel often exists alone on other occasions, and is usually used as an active viewing platform.
Ferris Wheel Structure
The main structure of the ring-shaped ferris wheel is a combined steel box girder structure, which is supported by a steel pipe truss on the inside and a closed game cabin on the outside of the box girder.
Principle of Ferris Wheel
The ferris wheel’s rim is closely attached to the outer frame, and the drive wheel is used to rotate the rim to make the sightseeing cabin rotate along the wheel’s frame. Passengers ride on the basement uniformly. The speed of the sightseeing warehouse is relatively slow, with an average speed of 0.2 m / s. At present, the types of structures that have been completed in China include the “Ring of Life” in Fushun City, Liaoning Province, and the landscape tower of the Changzhou Bauhinia Park.

The traditional ferris wheel uses the central axis as the main transmission device. The central axis drives the support frame connected between the central axis and the track to transmit torque. This method of transmitting torque requires too much torque from the central axis. The supporting frame that transmits the torque increases the overall weight of the ferris wheel and needs to consume additional power. In addition, multiple supporting frames form the windward surface, which increases the overall wind receiving area of the ferris wheel and increases the difficulty of the fixed support of the ferris wheel.
