An epicyclic gear teach (also called planetary gear) consists of two gears mounted to ensure that the centre of 1 gear revolves around the center of the other. A carrier links the Planetary Reducer Gearbox centres of both gears and rotates to transport one equipment, called the planet gear or world pinion, around the other, called sunlight gear or sun wheel. The earth and sunlight gears mesh so that their pitch circles roll without slip. A point on the pitch circle of the earth equipment traces an epicycloid curve. In this simplified case, sunlight equipment is set and the planetary equipment(s) roll around the sun gear.
An epicyclic gear teach can be assembled therefore the planet equipment rolls within the pitch circle of a fixed, outer gear ring, or ring gear, sometimes called an annular gear. In cases like this, the curve traced by a point on the pitch circle of the planet is a hypocycloid.
The combination 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 equipment is normally fixed and sunlight gear is driven.
Epicyclic gears obtain name from their earliest software, which was the modelling of the movements of the planets in the heavens. Believing the planets, as everything in the heavens, to become perfect, they could just travel in ideal circles, but their motions as seen from Earth could not become reconciled with circular motion. At around 500 BC, the Greeks invented 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, got gearing which was in a position to approximate the moon’s elliptical route through the heavens, and even to correct for the nine-12 months precession of that path.[3] (The Greeks could have seen it not as elliptical, but instead as epicyclic motion.)
EP, a versatile and multi-use option, is not just another simple planetary gearbox. EP high-tech planetary reducer is usually a genuine integrated concept, including many functions combined collectively to give you a complete sub-assembly to the most demanding machines.

The S Series design causes this gearmotor particularly effective for pump, blower applications and fan. To meet up the needs of clients in these sectors, the S Series can be available in the feet or flange editions and will be completed with an array of electric motors entirely created 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 consumers with a superb balance of cost performance, efficiency and dynamics.
