An epicyclic gear train (also known as planetary gear) contains two gears mounted so that the centre of one equipment revolves around the centre of the additional. A carrier connects the centres of the two gears and rotates to transport one equipment, called the planet gear or world pinion, around the various other, called the sun gear or sunlight wheel. The planet and sunlight gears mesh to ensure that their pitch circles roll without slip. A point on the pitch circle of the planet equipment traces an epicycloid curve. In this simplified case, the sun gear is set 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 equipment, sometimes named an annular gear. In cases like this, the curve traced by a spot on the pitch circle of the planet is a hypocycloid.
The mixture of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called a planetary gear train.[1][2] In this case, the ring gear is normally fixed and the sun gear is driven.
Epicyclic gears get their name from their earliest program, 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 seen from Earth cannot become reconciled with circular movement. At around 500 BC, the Greeks developed the idea 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 Mechanism, circa 80 BC, had gearing which was able to approximate the moon’s elliptical route through the heavens, and also to improve for the nine-year precession of that path.[3] (The Greeks could have seen it much less elliptical, but rather as epicyclic motion.)
EP, a versatile and multi-use solution, is not simply another simple planetary gearbox. EP high-tech planetary reducer is normally a true integrated concept, including some functions combined collectively to give a complete sub-assembly to the virtually all demanding machines.
EP is the best high-tech servo-reducer, specially focused on 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 productivity drive flange for mounting pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and good 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
Helical Single-Stage
The S Series design produces this gearmotor particularly effective for pump, blower applications and fan. To meet the needs of buyers in these sectors, the S Series can be available in the foot or flange variants and will be completed with an array of electric motors entirely manufactured by EP. Asynchronous motors both IEC and small (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 consumers with an outstanding balance of cost performance, dynamics and efficiency.
