planetary reducer gearbox

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

An epicyclic gear train can be assembled so the planet equipment rolls on the inside of the pitch circle of a set, outer gear band, or ring equipment, sometimes named an annular gear. In this case, the curve traced by a point on the pitch circle of the earth 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 instance, the ring gear is generally 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 be perfect, they could only travel in ideal circles, but their motions as viewed from Earth cannot end up being reconciled with circular movement. At around 500 BC, the Greeks Planetary Reducer Gearbox created the idea 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 System, circa 80 BC, had gearing which was able to approximate the moon’s elliptical route through the heavens, and even to improve for the nine-season precession of that route.[3] (The Greeks could have seen it much less elliptical, but rather as epicyclic motion.)

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