Gear Sets for Commercial Vehicles
Ever-Power new planetary reducers hire a floating sun gear rather than a set position one.
The word ”There’s nothing new beneath the sun’ certainly applies to planetary reducers. And, while floating sun gears have been around a long time, some engineers might 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 into the shaft. When this set sun equipment revolves, it turns the planet gears to create motion and/or power. Ever-Power new planetary reducers, however, are employing a floating sun equipment rather than a fixed position sun gear.
Why a floating sunlight equipment? ‘In the planetary concept, the sun may be the driver, or pinion, in the gear set,’Ever-Power design engineer Scott Hulstein said. ‘Because sunlight gear is in constant contact with the planets, it’s important that it is flawlessly centred among the three planets to be able to provide equal load posting among itself and all three planets.’
Due to normal manufacturing tolerances nevertheless, a sun equipment which is securely set upon a shaft will intermittently have more load on one planet equipment than on another equipment Hulstein explained. ‘By enabling the sun gear to float, it centres itself among the three planets and produces continuous, equal load sharing.’
Equal load posting is just one of the advantages of this design. The floating sunlight gear provides ‘true involute actions,’ according to Hulstein. True involute action happens when the rolling movement between your mating gears is really as complete as possible. The benefit of this full meshing of gears is longer reducer life, since less internal gear slippage means fewer damaged gear teeth.
That does mean lower noise amounts. When sunlight gear is permitted to completely roll into the planet gears, there’s much less ‘rattling’ as the teeth mesh. In place, the Ever-Power product provides ‘designed out’ the gear mesh sound by allowing sunlight equipment to float into place.
So why use a set sun gear at all? ‘Fixed sun gears are often used in accurate 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 application.’ Ever-Power engineers, however, were less worried about low backlash and more interested with higher torque and/or lower noise applications.
Our planetary reducers with floating sunlight gears were made to contend with parallel shaft reducers, where backlash was less critical,’ Pennings said.
Utilizing the floating sun gear concept, the Ever-Power planetary reducers have the ability to exceed the torque rankings of similar sized and larger sized parallel shaft reducers, yet maintain a lower noise levels.
Sun, Ring and Planet
The most basic kind of planetary gearset is proven in the figures above. The figure at still left shows a three-dimensional watch while the figure at correct provides a cross-section. In this geartrain, sun planet gear inputs and output can be taken from the carrier, band and sunlight gears, and only the planet experiences epicyclic motion. This is the many common kind of planetary gearset (apart from the differential) and it discovers application in swiftness reducers and automatic transmissions. Invest the aside a cordless drill, you’ll probably find this kind of planetary gearset directly behind the drill chuck.
Two Suns – Two Planets gearset
Two Suns, Two Planets
The gearset proven above has two sunlight gears, and both planet gears (the yellow gears) rotate as an individual unit. The sun gears (green and brownish) can rotate independently of one another. The inputs and output can be chosen from either sun equipment 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 – crimson 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 remaining and counterclockwise in the computer animation at right – despite the fact that sunlight rotates counterclockwise in both instances.
The gearset proven above differs from the preceding gearsets for the reason that it is made up of miter gears instead of spur (or helical) gears. The ‘sun’ gears are the ones that do not go through the epicyclic motion experienced by the planet. And the differential can be used to measure the difference in velocity between two shafts for the purpose of synchronization. Furthermore, the differential is frequently used in automotive drive trains to overcome the difference in wheel rate when a car encircles a corner.
