An epicyclic gear teach (also called planetary gear) contains two gears mounted so that the centre of 1 equipment revolves around the centre of the additional. A carrier links the centres of both gears and rotates to transport one equipment, called the earth gear or world pinion, around the additional, called the sun gear or sun wheel. The earth and sunlight gears mesh to ensure that their pitch circles roll without slide. A spot on the pitch circle of the earth 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 on the inside of the pitch circle of a fixed, outer gear band, or ring gear, sometimes called an annular gear. In cases like this, the curve traced by a point on the pitch circle of the earth is a hypocycloid.
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 equipment is usually fixed and sunlight gear is driven.
Epicyclic gears obtain name from their earliest app, which 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 just travel in perfect circles, but their motions as viewed from Earth could not become reconciled with circular motion. At around 500 BC, the Greeks invented the idea of epicycles, of circles venturing 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, got gearing which was able to approximate the moon’s elliptical route through the heavens, and even to improve for the nine-year precession of that route. (The Greeks would have seen it not as elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use option, is not only another simple planetary gearbox. EP high-tech planetary reducer is normally a true integrated concept, including different functions combined along to give you a complete sub-assembly to the virtually all demanding machines.
EP is the ultimate high-tech servo-reducer, specially dedicated to designs requiring:
Superior output torsional stiffness
Ultra-great 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 result drive flange for mounting pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and remarkable torque Planetary Reducer Gearbox 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 style causes this gearmotor particularly effective for fan, blower applications and pump. To meet up the needs of consumers in these sectors, the S Series can be available in the foot or flange variations and may 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 consumers with an outstanding balance of cost performance, efficiency and dynamics.
