Epicyclic gears get their name from their earliest application, which was the modelling of the Planetary Reducer Gearbox 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 perfect circles, but their motions as viewed from Earth cannot become reconciled with circular movement. At around 500 BC, the Greeks invented the thought of epicycles, of circles travelling on the circular orbits. With this theory Claudius Ptolemy in the Almagest in 148 AD was able to 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 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 remedy, is not only another simple planetary gearbox. EP high-tech planetary reducer is certainly a genuine integrated concept, including countless functions combined mutually to offer 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-great 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 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 possible for design engineers to find specific solutions to the most demanding applications.
Parallel shaft Gearmotors
Helical Single-Stage
The S Series style causes this gearmotor particularly effective for fan, pump and blower applications. To meet up the needs of consumers in these sectors, the S Series can be available in the feet or flange editions and can be completed with a wide selection 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 coupled with the S Series: with the breadth of its portfolio, EP provides consumers with a superb balance of dynamics, effectiveness 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 this instance, the ring gear is generally fixed and the sun gear is driven.
