An epicyclic gear teach (also referred to as planetary gear) consists of two gears mounted so that the centre of one gear revolves around the centre of the additional. A carrier links the centres of both gears and rotates to carry one gear, called the planet gear or world pinion, around the additional, called the sun gear or sun wheel. The planet and sun gears mesh to ensure that their pitch circles roll without slide. A point on the pitch circle of the planet equipment traces an epicycloid curve. In this simplified case, sunlight equipment is fixed and the planetary equipment(s) roll around sunlight gear.
An epicyclic gear teach can be assembled therefore the planet gear rolls within the pitch circle of a fixed, outer gear band, or ring equipment, sometimes named an annular equipment. In this case, 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 named a planetary gear train.[1][2] In this instance, the ring gear is normally fixed and sunlight 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 end up being perfect, they could just travel in perfect circles, but their motions as seen from Earth could not become reconciled with circular movement. At around 500 BC, the Greeks developed the thought 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 Mechanism, circa 80 BC, acquired gearing which was able to Planetary Reducer Gearbox approximate the moon’s elliptical path through the heavens, and actually to improve for the nine-season precession of that route.[3] (The Greeks could have seen it not as elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use alternative, is not only another simple planetary gearbox. EP high-tech planetary reducer can be a genuine integrated concept, including some functions combined along to give a complete sub-assembly to the virtually all demanding machines.
EP is the ultimate high-tech servo-reducer, specially focused on designs requiring:
Superior output torsional stiffness
Ultra-large output radial stiffness and Tilting moment
Patented output bearing design
A high-tech planetary gear train, predicated on REDEX’s differential know-how
ISO 9409-1 productivity drive flange for mounting pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and good torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or right angle arrangements
This versatile design helps it be easy for design engineers to 
find precise answers to the most demanding applications.
Parallel shaft Gearmotors
Helical Single-Stage
The S Series design produces this gearmotor particularly effective for fan, blower applications and pump. To meet up the needs of consumers in these sectors, the S Series is also available in the ft . or flange variants and can be completed with a variety 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 in conjunction with the S Series: with the breadth of its portfolio, EP provides buyers with an outstanding balance of efficiency, price effectiveness and dynamics.
