Epicyclic gears obtain name from their earliest app, 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 reconciled with circular movement. At around 500 BC, the Greeks created the thought of epicycles, of circles venturing on the circular orbits. With this theory Claudius Ptolemy in the Almagest in 148 AD was able to predict planetary orbital paths. The Antikythera System, circa 80 BC, experienced gearing which was able to approximate the moon’s elliptical route through the heavens, and also to correct for the nine-season precession of that route. (The Greeks would have seen it not as elliptical, but instead as epicyclic motion.)
EP, a versatile and multi-use solution, is not simply another simple planetary gearbox. EP high-tech planetary reducer is definitely a true integrated concept, including some functions combined jointly to give a complete sub-assembly to the virtually all demanding machines.
EP is the best high-tech servo-reducer, specially focused on designs Planetary Reducer Gearbox 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 productivity drive flange for installation pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and superb 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 precise solutions to the most demanding applications.
Parallel shaft Gearmotors
The S Series design causes this gearmotor particularly effective for blower applications, fan and pump. To meet the needs of consumers in these sectors, the S Series is also available in the feet or flange variants and will be completed with a variety of electric motors entirely produced by EP. Asynchronous motors both IEC and compact (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 consumers with an outstanding balance of cost performance, efficiency and dynamics.
The mixture of epicycle gear trains with a planet engaging both a sun gear and a ring gear is named a planetary gear train. In this case, the ring gear is generally fixed and sunlight gear is driven.
