An epicyclic gear teach (also known as planetary gear) includes two gears mounted to ensure that the centre of 1 equipment revolves around the center of the additional. A carrier links the centres of the two gears and rotates to carry one equipment, called the earth gear or world pinion, around the other, called the sun gear or sun wheel. The planet and sun gears mesh so that their pitch circles roll without slide. A point on the pitch circle of the earth equipment traces an epicycloid curve. In this simplified case, sunlight gear is fixed and the planetary gear(s) roll around the sun gear.

An epicyclic gear teach can be assembled so the planet equipment rolls Planetary Reducer Gearbox within the pitch circle of a fixed, outer gear band, or ring equipment, sometimes named an annular equipment. In cases like this, the curve traced by a spot 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 named 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 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 only travel in ideal circles, but their motions as seen from Earth could not become reconciled with circular movement. At around 500 BC, the Greeks created the thought of epicycles, of circles venturing 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 path through the heavens, and also to improve for the nine-calendar year precession of that route.[3] (The Greeks could have seen it much less elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use alternative, is not merely another simple planetary gearbox. EP high-tech planetary reducer is definitely a true integrated concept, including several functions combined together to provide 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-substantial output radial stiffness and Tilting moment
Patented output bearing design
A high-tech planetary equipment train, predicated on REDEX’s differential know-how
ISO 9409-1 outcome drive flange for installation pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and good torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or proper angle arrangements
This versatile design helps it be easy for design engineers to find actual solutions to the most demanding applications.
Parallel shaft Gearmotors
Helical Single-Stage
The S Series design makes this gearmotor particularly effective for fan, pump and blower applications. To meet up the needs of buyers in these sectors, the S Series is also available in the foot or flange types and will be completed with a wide selection 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) can be coupled with the S Series: with the breadth of its portfolio, EP provides consumers with a superb balance of cost efficiency, dynamics and efficiency.
