An epicyclic gear teach 
(also known as planetary gear) contains two gears mounted to ensure that the centre of 1 gear revolves around the center of the additional. A carrier connects the centres of both gears and rotates to transport one gear, called the earth gear or world pinion, around the other, called the sun gear or sunlight wheel. The earth and sunlight gears mesh to ensure that their pitch circles roll without slip. A point on the pitch circle of the earth gear traces an epicycloid curve. In this simplified case, sunlight gear is set and the planetary equipment(s) roll around the sun 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 gear, sometimes named 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 called a planetary gear train.[1][2] In this instance, the ring equipment is usually fixed and sunlight gear is driven.
Epicyclic gears obtain name from their earliest app, which 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 become reconciled with circular motion. At around 500 BC, the Planetary Reducer Gearbox Greeks developed 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, got gearing which was able to approximate the moon’s elliptical route through the heavens, and also to correct for the nine-yr precession of that path.[3] (The Greeks could have seen it much less elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use remedy, is not merely another simple planetary gearbox. EP high-tech planetary reducer is a genuine integrated concept, including several functions combined jointly to provide a complete sub-assembly to the virtually all demanding machines.
EP is the best high-tech servo-reducer, specially focused on designs requiring:
Superior output torsional stiffness
Ultra-huge output radial stiffness and Tilting moment
Patented output bearing design
A high-tech planetary gear train, based on REDEX’s differential know-how
ISO 9409-1 output drive flange for installation pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and remarkable torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or proper angle arrangements
This versatile design helps it be possible for design engineers to find precise solutions to the most demanding applications.
Parallel shaft Gearmotors
Helical Single-Stage
The S Series style makes this gearmotor particularly effective for fan, pump and blower applications. To meet the needs of consumers in these sectors, the S Series can be available in the ft . or flange editions and can 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 customers with a superb balance of dynamics, efficiency and cost effectiveness.
