Epicyclic gears get their name from their earliest app, which was the modelling of the actions 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 could not end up being reconciled with circular movement. At around 500 BC, the Greeks created the idea 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, experienced gearing which was in a position to approximate the moon’s elliptical route through the heavens, and even to improve for the nine-yr precession of that route. (The Greeks could have seen it much less elliptical, but instead as epicyclic motion.)
EP, a versatile and multi-use solution, is not only another simple planetary gearbox. EP high-tech planetary reducer is definitely a genuine integrated concept, including many functions combined collectively to give you a complete sub-assembly to the virtually all demanding machines.
EP is the best high-tech servo-reducer, specially dedicated to designs requiring:
Superior output torsional stiffness
Ultra-huge 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, Planetary Reducer Gearbox couplings, etc.
High input speeds
Superior acceleration and good torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or proper angle arrangements
This versatile design makes it possible for design engineers to find actual answers to the most demanding applications.
Parallel shaft Gearmotors
The S Series design produces this gearmotor particularly effective for pump, fan and blower applications. To meet the needs of consumers in these sectors, the S Series can be available in the foot or flange editions and can be completed with a variety 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) could be coupled with the S Series: with the breadth of its portfolio, EP provides consumers with a superb balance of cost efficiency, 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 instance, the ring gear is normally fixed and the sun gear is driven.
