Epicyclic gears obtain name from their earliest program, which was the modelling of the motions of the planets in the heavens. Believing the planets, as everything in the heavens, to become perfect, they could just travel in perfect circles, but their motions as viewed from Earth cannot end up being reconciled with circular motion. At around 500 BC, the Greeks developed the thought of epicycles, of circles traveling 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, acquired gearing which was able to approximate the moon’s elliptical route through the heavens, and also to improve for the nine-12 months precession of that route.[3] (The Greeks could have seen it not as elliptical, but instead as epicyclic motion.)
EP, a versatile and multi-use choice, is not merely another simple planetary gearbox. EP high-tech planetary reducer can be a true integrated concept, including many functions combined mutually to give a complete sub-assembly to the most demanding machines.
EP is the best high-tech servo-reducer, specially dedicated to designs requiring:
Superior output torsional stiffness
Ultra-great 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 outcome drive flange for installation pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and exceptional torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or correct angle arrangements
This versatile design helps it be Planetary Reducer Gearbox possible for design engineers to find exact answers to the most demanding applications.
Parallel shaft Gearmotors
Helical Single-Stage
The S Series design makes this gearmotor particularly effective for pump, fan and blower applications. To meet the needs of consumers in these sectors, the S Series can be available in the foot or flange versions and can be completed with a variety of electric motors entirely produced 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 buyers with an outstanding balance of cost efficiency, efficiency and dynamics.

The combination 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 generally fixed and sunlight gear is driven.
