An epicyclic gear teach (also known as planetary gear) consists of two gears mounted so that the centre of one equipment revolves around the center of the other. A carrier connects the centres of the two gears and rotates to carry one equipment, called the planet gear or world pinion, around the various other, called the sun gear or sun wheel. The earth and sunlight gears mesh to ensure that their pitch circles roll without slide. A spot on the pitch circle of the earth equipment traces an epicycloid curve. In this simplified case, the sun equipment is fixed and the planetary gear(s) roll around the sun gear.
An epicyclic gear train can be assembled so the planet gear rolls on the inside of the pitch circle of a fixed, outer gear band, or ring gear, sometimes called an annular gear. In this case, the curve traced by a spot 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. In cases like this, the ring equipment is generally fixed and the sun gear is driven.
Epicyclic gears get their name from their earliest program, that was the modelling of the motions of the planets in the heavens. Believing the planets, as everything in the heavens, to be perfect, they could only travel in perfect circles, but their motions as viewed from Earth could not end up being reconciled with circular motion. At around 500 BC, the Greeks invented the idea of epicycles, of circles travelling on the circular orbits. With this theory Claudius Ptolemy in the Almagest in 148 AD could predict planetary orbital paths. The Antikythera Mechanism, circa 80 BC, had gearing which was able to approximate the moon’s elliptical route through the heavens, and actually to correct for the nine-season precession of that route. (The Greeks would have seen it not as elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use answer, 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 a complete sub-assembly to the virtually all demanding machines.

The S Series design may make this gearmotor particularly effective for fan, pump and blower applications. To meet up the needs of buyers in these sectors, the S Series can be available in the ft . or flange variations and can be completed with an array 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 consumers with a superb balance of dynamics, performance and cost effectiveness.
