epicycle's Usage Examples:

In the Hipparchian, Ptolemaic, and Copernican systems of astronomy, the epicycle (from Ancient Greek: ἐπίκυκλος, literally upon the circle, meaning circle.

The combination of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called.

the path of a chosen point on the circumference of a circle—called an epicycle—which rolls without slipping around a fixed circle.

A given planet then moves around the epicycle at the same time the epicycle moves along the path marked by the deferent.

a deferent and epicycle model, the deferent carries a small circle, the epicycle, which carries the planet.

The deferent-and-epicycle model can mimic.

equant point, the epicycle's center (indicated by the small · ) would appear to move at a steady angular speed.

However, the epicycle's center will not.

allowed an equant in an astronomic model to be replaced with an equivalent epicycle that moved around a deferent centered at half the distance to the equant.

accuracy which led him to eliminate the epicycle in the Ptolemaic solar model and all the eccentrics, epicycles and equant in the Ptolemaic lunar model.

could have encountered such a model, where the primary epicycle carries the center of a second epicycle.

Earth): 3144 : 327+2⁄3 ; and for the epicycle model, the ratio between the radius of the deferent and the epicycle: 3122+1⁄2 : 247+1⁄2 .

of the deferent moves on a secondary epicycle, al-Zarqālī noted that the path of the center of the primary epicycle is not a circle, as it is for the other.

is transmitted through a single main transmission and then through an epicycle gear final drive on each side.

deferent, carrying an epicycle along which the Moon was assumed to move in a retrograde direction.

The center of the epicycle moved at a rate corresponding.
