Epicyclic gears get their name from their earliest program, that was the modelling of the motions of the planets in the heavens. Believing the planets, as everything in the heavens, to end up being perfect, they could only travel in ideal circles, but their motions as viewed from Earth could not be reconciled with circular motion. At around 500 BC, the Greeks invented 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 Mechanism, circa 80 BC, got gearing which was in a position to approximate the moon’s elliptical route through the heavens, and also to correct for the nine-12 months precession of that route. (The Greeks could have seen it much less elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use choice, is not merely another simple planetary gearbox. EP high-tech planetary reducer is certainly a true integrated concept, including more than a few functions combined alongside one another to offer a Planetary Reducer Gearbox 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-substantial 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 result drive flange for mounting pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and superb torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or proper angle arrangements
This versatile design makes it 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 buyers in these sectors, the S Series can be available in the feet or flange variations and will be completed with a wide selection 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 clients with an outstanding balance of dynamics, performance and cost effectiveness.
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 usually fixed and sunlight gear is driven.
