epicyclical การใช้

It was steered by an epicyclical transmission combined with hydraulically reinforced brake disks, which failed to provide the desired precision during tests.
Because of its reliance on special epicyclical gearwheels rather than levers, this incredible watch can be quickly adjusted both forwards and backwards!
Though most hub gear systems use one rear sprocket, Canyon introduced the 144 2, a hybrid hub which uses a similar epicyclical / derailleur combination.
One sphere / slice is the deferent, with a centre offset somewhat from the Earth; the other sphere / slice is an epicycle embedded in the deferent, with the planet embedded in the epicyclical sphere / slice.
Epicyclical motion is used in the Antikythera mechanism, an ancient Greek astronomical device for compensating for the elliptical orbit of the Moon, moving faster at perigee and slower at apogee than circular orbits would, using four gears, two of them engaged in an eccentric way that quite closely approximates Kepler's second law.
