Gear Sets for Industrial Vehicles
Ever-Power new planetary reducers employ a floating sun gear rather than a set position one.
The saying ”There’s nothing new beneath the sun’ certainly applies to planetary reducers. And, while floating sunlight gears have been around quite a while, some engineers might not become aware of the huge benefits this unusual gear style can offer.
Traditionally, planetary reducers have used a set sun gear, where the centre gear is attached to or machined into the shaft. When this set sun equipment revolves, it turns the earth gears to create motion 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 sunlight gear? ‘In the planetary concept, the sun may be the driver, or pinion, in the gear set,’Ever-Power style engineer Scott Hulstein said. ‘Because the sun gear is in continuous contact with the planets, it’s important that it is perfectly centred among the three planets in order to provide equal load posting among itself and all three planets.’
Because of normal manufacturing tolerances nevertheless, a sun gear which is securely set upon a shaft will intermittently have sun planet gear significantly more load on one planet gear than on another equipment Hulstein explained. ‘By permitting the sun equipment to float, it centres itself among the three planets and generates constant, equal load sharing.’
Equal load posting is merely one of the benefits of this design. The floating sunlight gear provides ‘accurate involute action,’ according to Hulstein. True involute action takes place when the rolling motion between your mating gears is really as complete as possible. The advantage of this full meshing of gears is longer reducer lifestyle, since less internal gear slippage means fewer damaged gear teeth.
That does mean lower noise levels. When sunlight gear is allowed to completely roll in to the planet gears, there’s less ‘rattling’ as one’s teeth mesh. In effect, the Ever-Power product offers ‘designed out’ the gear mesh noise by allowing sunlight equipment to float into place.
So why use a set sun gear at almost all? ‘Fixed sun gears tend to be used in true servo applications,’ Greg Pennings, Ever-Power Consumer Advocate, explained. ‘A fixed sun gear is essential when exact positioning and low backlash are an intrinsic part of the program.’ Ever-Power engineers, nevertheless, were less worried about low backlash and more interested with higher torque and/or lower noise 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 equipment concept, the Ever-Power planetary reducers are able to exceed the torque ratings of similar sized and bigger sized parallel shaft reducers, yet maintain a lesser noise levels.
Sun, Ring and Planet
The most basic type of planetary gearset is demonstrated in the figures above. The figure at remaining shows a three-dimensional view as the figure at right offers a cross-section. In this geartrain, inputs and result can be taken from the carrier, ring and sunlight gears, and only the planet experiences epicyclic motion. That is the the majority of common type of planetary gearset (with the exception of the differential) and it discovers application in quickness reducers and automatic transmissions. Invest the aside a cordless drill, you’ll probably find this kind of planetary gearset right behind the drill chuck.
Two Suns – Two Planets gearset
Two Suns, Two Planets
The gearset proven above has two sun gears, and both planet gears (the yellow gears) rotate as a single unit. The sun gears (green and brown) can rotate independently of 1 another. The inputs and output can be chosen from either sun gear and/or the carrier. High speed reductions may be accomplished with this unit, nonetheless it can have problems with low efficiency if not designed correctly.

Purple sun input – reddish colored sun fixed
The animations above show the ‘two suns – two planets’ gearset with one sunlight as input and the other sunlight fixed. Note that the carrier rotates clockwise in the animation at still left and counterclockwise in the computer animation at right – despite the fact that sunlight rotates counterclockwise in both situations.
The gearset shown above differs from the preceding gearsets for the reason that it is composed of miter gears rather than spur (or helical) gears. The ‘sun’ gears are those that do not undergo the epicyclic motion experienced by the planet. And the differential can be used to gauge the difference in velocity between two shafts for the purpose of synchronization. Furthermore, the differential is often used in automotive drive trains to overcome the difference in wheel swiftness when a car goes around a corner.
