An epicyclic gear teach (also known as planetary gear) contains two gears mounted to ensure that the centre of one gear revolves around the center of the other. A carrier connects the centres of both gears and rotates to carry one equipment, called the planet gear or planet pinion, around the various other, called sunlight gear or sunlight wheel. The earth and sunlight gears mesh to ensure that their pitch circles roll without slip. A spot on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, the sun gear is fixed and the planetary equipment(s) roll around the sun gear.
An epicyclic gear teach can be assembled so the planet equipment rolls on the inside of the pitch circle of a set, outer gear band, or ring equipment, sometimes named an annular gear. In this instance, the curve traced by a spot 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 called a planetary gear train.[1][2] In cases like this, the ring gear is usually fixed and the sun 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 only travel in ideal circles, but their motions as viewed from Earth cannot become reconciled with circular movement. At around 500 BC, the Greeks created the idea of epicycles, of circles traveling 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, got gearing which was able to approximate the moon’s elliptical path through the heavens, and also to improve for the nine-12 months precession of that path.[3] (The Greeks could have seen it much less elliptical, but instead as epicyclic motion.)
EP, a versatile and multi-use remedy, is not only another simple planetary gearbox. EP high-tech planetary reducer is usually a true integrated concept, including some functions combined together to offer a complete sub-assembly to the most demanding machines.
EP is the best high-tech servo-reducer, specially dedicated to designs Planetary Reducer Gearbox requiring:
Superior output torsional stiffness
Ultra-large 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 good torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or right angle arrangements
This versatile design helps it be possible for design engineers to find precise solutions to the most demanding applications.
Parallel shaft Gearmotors
Helical Single-Stage
The S Series style causes this gearmotor particularly effective for pump, blower applications and fan. To meet the needs of consumers in these sectors, the S Series is also available in the feet or flange versions and can be completed with an array of electric motors entirely created 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 consumers with an outstanding balance of dynamics, price effectiveness and efficiency.
