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

An epicyclic gear teach can be assembled so the planet equipment rolls on the inside of the pitch circle of a set, outer gear ring, or ring gear, sometimes named an annular gear. In cases like this, 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 called a planetary gear train.[1][2] In this case, the ring gear is normally fixed and the sun gear is driven.

Epicyclic gears get their name from their earliest application, that was the modelling of the motions of the planets in the heavens. Believing the planets, as everything in the heavens, to end up being perfect, they could only travel in ideal circles, but their motions as viewed from Earth cannot become reconciled with circular motion. At around 500 BC, the Greeks created the idea of epicycles, of circles venturing 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, experienced gearing which was able to approximate the moon’s elliptical path through the heavens, and even to improve for the nine-year precession of that route.[3] (The Greeks would have seen it much less elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use answer, is not only another simple planetary gearbox. EP high-tech planetary reducer is usually a genuine integrated concept, including many functions combined mutually to give you a complete sub-assembly to the most demanding machines.

The S Series design may make this gearmotor particularly effective for pump, blower applications and fan. To meet the needs of customers in these sectors, the S Series can be available in the feet or flange variations and can be completed with a wide selection of electric motors entirely made by EP. Asynchronous motors both IEC and small (B-BE-BX/M-ME-MX), servomotors (BMD) and reluctance motors (BSR) can be in conjunction with the S Series: with the breadth of its portfolio, EP provides buyers with a superb balance of efficiency, cost effectiveness and dynamics.
