Epicyclic gears get their name from their earliest software, that was the modelling of the movements of the planets in the heavens. Believing the planets, as everything in the heavens, to end up being perfect, they could just travel in ideal circles, but their motions as viewed from Earth cannot become Planetary Reducer Gearbox reconciled with circular motion. At around 500 BC, the Greeks invented 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 System, circa 80 BC, acquired gearing which was able to approximate the moon’s elliptical path through the heavens, and actually to improve for the nine-yr precession of that path.[3] (The Greeks would have seen it not as elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use option, is not merely another simple planetary gearbox. EP high-tech planetary reducer can be a true integrated concept, including several functions combined together to offer a complete sub-assembly to the most 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, 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 excellent 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 actual answers to the most demanding applications.
Parallel shaft Gearmotors
Helical Single-Stage
The S Series design makes this gearmotor particularly effective for blower applications, pump and fan. To meet the needs of customers in these sectors, the S Series can be available in the foot or flange types and can be completed with a wide 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) can be in conjunction with the S Series: with the breadth of its portfolio, EP provides buyers with an outstanding balance of efficiency, dynamics and cost effectiveness.

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 case, the ring equipment is usually fixed and the sun gear is driven.
