Epicyclic gears get their name from their earliest application, 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 perfect 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 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 even to improve for the nine-calendar year precession of that route. (The Greeks would have seen it not as elliptical, but instead as epicyclic motion.)
EP, a versatile and multi-use remedy, is not only another simple planetary gearbox. EP high-tech planetary reducer is usually a genuine integrated concept, including more than a few functions combined alongside one another to give you a complete sub-assembly to the virtually all demanding machines.
EP is the best high-tech servo-reducer, specially focused on designs requiring:
Superior output torsional stiffness
Ultra-high output radial stiffness and Tilting moment
Patented output bearing design
A high-tech planetary gear train, based on REDEX’s differential know-how
ISO 9409-1 productivity 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 correct angle arrangements
This versatile design makes it possible for design engineers to find exact answers to the most demanding applications.
Parallel shaft Gearmotors
The S Series style makes this gearmotor particularly effective for pump, blower applications and fan. To meet the needs of consumers in these sectors, the S Series can be available in the feet or flange editions and will be completed with a wide 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) could be in Planetary Reducer Gearbox conjunction with the S Series: with the breadth of its portfolio, EP provides customers with a superb balance of cost efficiency, dynamics and efficiency.
The combination of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called a planetary gear train. In this instance, the ring gear is normally fixed and sunlight gear is driven.
