An epicyclic gear teach (also known as planetary gear) consists of two gears mounted to ensure that the centre of one gear revolves around the center of the various other. A carrier connects the centres of the two gears and rotates to carry one equipment, called the planet gear or world pinion, around the various other, called the sun gear or sun wheel. The planet and sun gears mesh so that their pitch circles roll without slide. A point on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, sunlight equipment is fixed and the planetary gear(s) roll around sunlight gear.
An epicyclic gear train can be assembled therefore the planet gear rolls within the pitch circle of a set, outer gear band, or ring gear, sometimes named an annular gear. In this case, the curve traced by a point on the pitch circle of the planet is a hypocycloid.
The combination 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.
Epicyclic gears obtain name from their earliest application, which was the modelling of the movements of the planets in the heavens. Believing the planets, as everything in the heavens, to become perfect, they could just travel in perfect circles, but their motions as seen from Earth cannot end up being reconciled with circular motion. 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 was able to predict planetary orbital paths. The Antikythera Mechanism, circa 80 BC, experienced 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 remedy, is not just another simple planetary gearbox. EP high-tech planetary reducer is usually a genuine integrated concept, including different functions combined along to offer a complete sub-assembly to the most demanding Planetary Reducer Gearbox machines.
EP is the ultimate high-tech servo-reducer, specially dedicated to 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 productivity 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 exact answers to the most demanding applications.
Parallel shaft Gearmotors
The S Series design may make this gearmotor particularly effective for fan, blower applications and pump. To meet the needs of customers in these sectors, the S Series can be available in the feet or flange versions and can be completed with a 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) can be in conjunction with the S Series: with the breadth of its portfolio, EP provides consumers with an outstanding balance of cost effectiveness, efficiency and dynamics.
