Coffee Cup Rides


Coffee Cup Rides is one of amusement park rides. The spinning movement is based on planetary gear. Three types of gear sets are available with different rotation speed on this model. It is very easy to exchange these gears.

Furthermore, you will understand the mechanism of planetary gears by building the model. The planetary gear train consists of a sun gear, planet gears supported by the carrier and a ring gear. The number of planet gears and the number of gear teeth must satisfy three conditions. These conditions were shown in the following video. Actually three gear sets in the model are the only possibility for single-pinion planetary gear using a banana gear for a ring gear.

Please have a look at the video.
