Gear Sets for Commercial Vehicles
Ever-Power new planetary reducers hire a floating sun equipment rather than a fixed position one.
The word ”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 become aware of the benefits this unusual gear design 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 equipment revolves, it turns the planet 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 equipment? ‘In the planetary idea, the sun is the driver, or pinion, in the gear set,’Ever-Power style engineer Scott Hulstein said. ‘Because the sun gear is in continuous connection with the planets, it’s important that it is flawlessly centred among the three planets in order to provide equal load posting among itself and all three planets.’
Due to normal manufacturing tolerances nevertheless, a sun equipment which is securely fixed on a shaft will intermittently have more load on one planet gear than on another equipment Hulstein explained. ‘By allowing the sun gear to float, it centres itself among the three planets and produces continuous, equal load sharing.’
Equal load posting is merely one of the benefits of this design. The floating sunlight gear provides ‘accurate involute actions,’ according to Hulstein. Accurate involute action occurs when the rolling motion between your mating gears is really as complete as feasible. The benefit of this total meshing of gears can be 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 world gears, there’s much less ‘rattling’ as one’s teeth mesh. In effect, the Ever-Power product has ‘designed out’ the gear mesh noise by allowing the sun gear to float into place.
So why make use of a set sun gear at most? ‘Fixed sun gears tend to be used in true servo applications,’ Greg Pennings, Ever-Power Customer Advocate, explained. ‘A fixed sun gear is essential when precise positioning and low backlash are an intrinsic part of the app.’ Ever-Power engineers, nevertheless, were less worried about low backlash and more interested with higher torque and/or lower sound applications.
Our planetary reducers with floating sunlight gears were designed to contend 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 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 shown in the figures above. The figure at remaining shows a three-dimensional watch while the figure at correct offers a cross-section. In this geartrain, inputs and result can be extracted from the carrier, ring and sunlight gears, and just the planet experiences epicyclic motion. That is the most common kind of planetary gearset (apart from the differential) and it discovers application in quickness reducers and automatic transmissions. Invest the aside a cordless drill, you’ll probably find this type of planetary gearset directly behind the drill chuck.
Two Suns – Two Planets gearset
Cross-sectional view
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. Sunlight gears (green and dark brown) can rotate independently of 1 another. The inputs and result can be chosen from either sun gear and/or the carrier. High speed reductions may be accomplished with this unit, but it can have problems with 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. Note that 
the carrier rotates clockwise in the computer animation at left and counterclockwise in the animation at right – even though sunlight rotates counterclockwise in both cases.
The Differential
The gearset proven above differs from the preceding gearsets for the reason that it is composed of miter gears instead of spur (or helical) gears. The ‘sun’ gears are the ones that do not go through the epicyclic movement experienced by the planet. And the differential can be used to measure the difference in quickness between two shafts for the purpose of synchronization. Furthermore, the differential is often used in auto drive trains to overcome the difference in wheel swiftness when a car encircles a corner.
