Epicyclic gears get their name from their earliest program, that was the modelling of the movements of the planets in the heavens. Believing the planets, as everything in the heavens, to be perfect, they could only travel in ideal circles, but their motions as viewed from Earth cannot be reconciled with circular movement. At around 500 BC, the Greeks created the idea 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 System, circa 80 BC, acquired gearing which was in a Planetary Reducer Gearbox position to approximate the moon’s elliptical route through the heavens, and also to improve for the nine-yr precession of that route. (The Greeks would have seen it much less elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use alternative, is not simply another simple planetary gearbox. EP high-tech planetary reducer is normally a genuine integrated concept, including many functions combined mutually to provide 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-high output radial stiffness and Tilting moment
Patented output bearing design
A high-tech planetary equipment 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 wonderful torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or proper angle arrangements
This versatile design helps it be easy for design engineers to find actual solutions to the most demanding applications.
Parallel shaft Gearmotors
The S Series style may make 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 foot or flange variants and will be completed with an array of electric motors entirely manufactured 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 clients with an outstanding balance of dynamics, expense effectiveness and efficiency.
The mixture of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called a planetary gear train. In cases like this, the ring gear is normally fixed and sunlight gear is driven.
