If you roll each circle along a 4-inch line, the first circle will cover the distance in a single full rotation; since the second circle's circumference is half that of the first circle, it has to complete two full rotations to cover the same distance. This explains why the two gears,...
Understanding the concept of the gear ratio is easy if you understand the concept of the circumference of a circle—the distance around the circle's perimeter. Let's say that you have circle whose circumference is 4 inches and a circle whose circumference is 2 inches. If you roll each circl...

The outer circumference of the cage assembly 40 is intercepted by the chord of a circle of a radius different than that of the cage diameter. The center of the chord is displaced from the center of the rotational member and cage assembly. The chord is formed on a flat plane support. ...
When the inclined angle of the pump swash plate 523 is close to the maximum positive inclined angle, the main transmission output shaft 512 rotates at the minimum speed (substantially zero) (see an outline circle mark in Fig. 23). In this embodiment, the traveling machine body 2 is ...
