An epicyclic gear train (also known as planetary gear) includes two gears mounted so that the centre of 1 gear revolves around the center of the additional. A carrier connects the centres of both gears and rotates to carry one gear, called the earth gear or planet pinion, around the additional, called the sun gear or sun wheel. The earth and sunlight gears mesh so that their pitch circles roll without slide. A spot on the pitch circle of the earth equipment traces an epicycloid curve. In this simplified case, the sun gear 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 set, outer gear ring, or ring equipment, sometimes named an annular equipment. In cases like this, the curve traced by a spot on the pitch circle of the earth 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 cases like this, the ring equipment is normally fixed and the sun gear is driven.
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 be perfect, they could just travel in perfect circles, but their motions as viewed from Earth Planetary Reducer Gearbox cannot be reconciled with circular movement. At around 500 BC, the Greeks created the thought of epicycles, of circles venturing 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 path through the heavens, and also to correct for the nine-season precession of that route. (The Greeks could have seen it much less elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use alternative, is not only another simple planetary gearbox. EP high-tech planetary reducer is a genuine integrated concept, including different functions combined together to give 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-huge 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 installation pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and exceptional torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or correct angle arrangements
This versatile design helps it be possible for design engineers to find actual answers to the most demanding applications.
Parallel shaft Gearmotors
The S Series style makes this gearmotor particularly effective for blower applications, pump and fan. To meet up the needs of buyers in these sectors, the S Series is also available in the foot or flange types and will be completed with an array 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) could be in conjunction with the S Series: with the breadth of its portfolio, EP provides buyers with an outstanding balance of cost effectiveness, efficiency and dynamics.
