Epicyclic gears get their name from their earliest app, that was the modelling of the motions of the planets in the heavens. Believing the planets, as everything in the heavens, to be perfect, they could just travel in perfect circles, but their motions as seen from Earth cannot become reconciled with circular movement. At around 500 BC, the Greeks Planetary Reducer Gearbox developed the thought of epicycles, of circles travelling on the circular orbits. With this theory Claudius Ptolemy in the Almagest in 148 AD could predict planetary orbital paths. The Antikythera System, circa 80 BC, got gearing which was able to approximate the moon’s elliptical route through the heavens, and actually to improve for the nine-12 months precession of that path. (The Greeks would have seen it much less elliptical, but instead as epicyclic motion.)
EP, a versatile and multi-use choice, is not only another simple planetary gearbox. EP high-tech planetary reducer is definitely a genuine integrated concept, including different functions combined along to offer a complete sub-assembly to the most demanding machines.
EP is the best high-tech servo-reducer, specially dedicated to designs requiring:
Superior output torsional stiffness
Ultra-excessive 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 mounting 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 makes it possible for design engineers to find specific answers to the most demanding applications.
Parallel shaft Gearmotors
The S Series design produces this gearmotor particularly effective for blower applications, fan and pump. To meet up the needs of customers in these sectors, the S Series is also available in the ft . or flange types and will be completed with an array 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) could be coupled with the S Series: with the breadth of its portfolio, EP provides buyers with an outstanding balance of efficiency, dynamics and cost effectiveness.
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 this case, the ring gear is generally fixed and the sun gear is driven.
