Epicyclic gears get their name from their earliest software, that was the modelling of the motions of the planets in the heavens. Believing the planets, as everything in the Planetary Reducer Gearbox heavens, to end up being perfect, they could just travel in ideal circles, but their motions as viewed from Earth cannot become 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, had gearing which was in a position to approximate the moon’s elliptical route through the heavens, and even to correct for the nine-year precession of that path.[3] (The Greeks would have seen it not as elliptical, but instead as epicyclic motion.)
EP, a versatile and multi-use option, is not only another simple planetary gearbox. EP high-tech planetary reducer is definitely a genuine integrated concept, including more than a few functions combined together to give you a complete sub-assembly to the virtually all 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 gear train, predicated on REDEX’s differential know-how
ISO 9409-1 output drive flange for mounting pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and superb torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or correct 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 causes this gearmotor particularly effective for pump, blower applications and fan. To meet up the needs of consumers in these sectors, the S Series can be available in the ft . or flange editions and will be completed with a wide selection 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 coupled with the S Series: with the breadth of its portfolio, EP provides clients with a superb balance of cost performance, 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 gear is normally fixed and the sun gear is driven.
