An epicyclic gear teach (also known as planetary gear) includes two gears mounted to ensure that the centre of 1 equipment revolves around the centre of the additional. A carrier connects the centres of both gears and rotates to carry one equipment, called the earth gear or planet pinion, around the additional, called the sun gear or sunlight wheel. The earth and sunlight gears mesh to ensure that their pitch circles roll without slide. A point on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, the sun equipment is fixed and the planetary equipment(s) roll around sunlight gear.

An epicyclic gear train can be assembled so the planet gear rolls within the pitch circle of a set, outer gear ring, or ring equipment, sometimes named an annular equipment. In this case, the curve traced by a point on the pitch circle of the planet is a hypocycloid.

The mixture of epicycle gear trains with a planet engaging both a sun gear and a ring gear is named a planetary gear train.[1][2] In this instance, the ring gear is generally fixed and the sun gear is driven.

Epicyclic gears obtain name from their earliest program, which was the modelling of the movements of the planets in the heavens. Believing the planets, as everything in the heavens, to be perfect, they could only Planetary Reducer Gearbox travel in perfect circles, but their motions as seen from Earth cannot be reconciled with circular movement. At around 500 BC, the Greeks created the thought of epicycles, of circles travelling on the circular orbits. With this theory Claudius Ptolemy in the Almagest in 148 AD was able to predict planetary orbital paths. The Antikythera Mechanism, circa 80 BC, had gearing which was in a position to approximate the moon’s elliptical route through the heavens, and also to improve for the nine-year precession of that path.[3] (The Greeks could have seen it not as elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use option, is not only another simple planetary gearbox. EP high-tech planetary reducer is a true integrated concept, including countless functions combined alongside one another to provide a complete sub-assembly to the virtually all demanding machines.

The S Series design produces this gearmotor particularly effective for blower applications, fan and pump. To meet up the needs of buyers in these sectors, the S Series is also available in the feet or flange editions and may be completed with an array of electric motors entirely produced by EP. Asynchronous motors both IEC and compact (B-BE-BX/M-ME-MX), servomotors (BMD) and reluctance motors (BSR) could be in conjunction with the S Series: with the breadth of its portfolio, EP provides clients with a superb balance of dynamics, efficiency and cost effectiveness.
