Epicyclic gears get their 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 be perfect, they could only travel in perfect circles, but their motions as seen from Earth could not be 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 Reducer Gearbox planetary orbital paths. The Antikythera Mechanism, circa 80 BC, had gearing which was in a position to approximate the moon’s elliptical path through the heavens, and actually to improve for the nine-12 months 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 option, is not only another simple planetary gearbox. EP high-tech planetary reducer is a genuine integrated concept, including countless functions combined alongside one another to give you a complete sub-assembly to the most demanding machines.
EP is the ultimate high-tech servo-reducer, specially dedicated to designs requiring:
Superior output torsional stiffness
Ultra-large output radial stiffness and Tilting moment
Patented output bearing design
A high-tech planetary equipment train, based on REDEX’s differential know-how
ISO 9409-1 end result drive flange for mounting 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 makes it possible for design engineers to find exact answers 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 up the needs of customers in these sectors, the S Series can be available in the ft . or flange types and may be completed with a broad range of electric motors entirely created by EP. Asynchronous motors both IEC and small (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 dynamics, proficiency and cost effectiveness.
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 cases like this, the ring equipment is usually fixed and the sun gear is driven.
