Gear Sets for Industrial Vehicles

Ever-Power new planetary reducers hire a floating sun gear rather than a fixed position one.
The saying ”There’s nothing new under the sun’ certainly applies to planetary reducers. And, while floating sunlight gears have already been around quite a while, some engineers may not end up being aware of the huge benefits this unusual gear style can offer.
Traditionally, planetary reducers have used a fixed sun gear, where in fact the centre gear is attached to or machined in to the shaft. When this set sun gear revolves, it turns the planet gears to create movement and/or power. Ever-Power new planetary reducers, however, are employing a floating sun gear rather than a set position sun gear.
Why a floating sun gear? ‘In the planetary concept, the sun is the driver, or pinion, in the apparatus set,’Ever-Power style engineer Scott Hulstein said. ‘Because sunlight gear is in continuous contact with the planets, it’s important that it’s perfectly centred among the three planets to be able to provide equal load posting among itself and all three planets.’
Due to normal manufacturing tolerances however, a sun gear which is securely set on a shaft will intermittently have more load using one planet gear than on another equipment Hulstein explained. ‘By enabling the sun equipment to float, it centres itself among the three planets and creates continuous, equal load sharing.’
Equal load sharing is merely one of the advantages of this design. The floating sunlight gear provides ‘accurate involute actions,’ according to Hulstein. True involute action takes place when the rolling motion between your mating gears is really as complete as feasible. The advantage of this complete meshing of gears is usually longer reducer existence, since less internal gear slippage means fewer broken gear teeth.
That also means lower noise amounts. When the sun gear is permitted to completely roll in to the world gears, there’s less ‘rattling’ as the teeth mesh. In effect, the Ever-Power product has ‘designed out’ the apparatus mesh noise by allowing sunlight equipment to float into place.
So why use a fixed sun gear at most? ‘Fixed sun gears are often used in true servo applications,’ Greg Pennings, Ever-Power Client Advocate, explained. ‘A set sun gear is necessary when precise positioning and low backlash are an integral part of the app.’ Ever-Power engineers, however, were less worried about low backlash and more interested with higher torque and/or lower sound applications.
Our planetary reducers with floating sun gears were designed to compete with parallel shaft reducers, where backlash was less critical,’ Pennings said.
By using the floating sun gear concept, the Ever-Power planetary reducers have the ability to exceed the torque ratings of similar sized and larger sized parallel shaft reducers, and yet maintain a lesser noise levels.
Sun, Ring and Planet
The most basic kind of planetary gearset is proven in the figures above. The figure at remaining shows a three-dimensional watch as the figure at correct offers a cross-section. In this geartrain, inputs and output can be taken from the carrier, band and sunlight gears, and just the planet experiences sun planet gear epicyclic motion. This is the many common kind of planetary gearset (with the exception of the differential) and it discovers application in quickness reducers and automatic transmissions. Invest the apart a cordless drill, you will most probably find this kind of planetary gearset directly behind the drill chuck.

Two Suns, Two Planets
The gearset proven above has two sun gears, and the two planet gears (the yellow gears) rotate as a single unit. The sun gears (green and brown) can rotate independently of one another. The inputs and result can be chosen from either sun equipment and/or the carrier. High speed reductions can be achieved with this unit, but it can suffer from low efficiency if not really designed correctly.

The animations above show the ‘two suns – two planets’ gearset with one sunlight as input and the other sunlight fixed. Remember that the carrier rotates clockwise in the computer animation at still left and counterclockwise in the animation at right – even though the sun rotates counterclockwise in both cases.
The Differential
The gearset proven above differs from the preceding gearsets in that it is made up of miter gears rather than spur (or helical) gears. The ‘sun’ gears are the ones that do not undergo the epicyclic motion experienced by the earth. And the differential can be used to gauge the difference in acceleration between two shafts for the purpose of synchronization. Furthermore, the differential is often used in auto drive trains to get over the difference in wheel speed when a car encircles a corner.
