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 beneath the sun’ certainly pertains to planetary reducers. And, while floating sun gears have already been around a long time, some engineers may not end up being aware of the benefits this unusual gear style can offer.
Traditionally, planetary reducers have used a fixed sun gear, where in fact the centre gear is mounted on or machined in to 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 having a floating sun gear rather than a fixed position sun gear.
Why a floating sun gear? 
‘In the planetary idea, the sun may be the driver, or pinion, in the gear set,’Ever-Power design engineer Scott Hulstein said. ‘Because sunlight gear is in continuous contact with the planets, it’s important that it is properly centred among the three planets in order to provide equal load posting among itself and all three planets.’
Due to normal manufacturing tolerances however, a sun equipment which is securely fixed on a shaft will intermittently have significantly 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 generates continuous, equal load sharing.’
Equal load posting is merely one of the benefits of this design. The floating sunlight gear provides ‘true involute actions,’ according to Hulstein. Accurate involute action occurs when the rolling movement between your mating gears is as complete as feasible. The advantage of this total meshing of gears is definitely 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 into the world gears, there’s less ‘rattling’ as one’s teeth mesh. In place, the Ever-Power product has ‘designed out’ the apparatus mesh noise by allowing sunlight gear to float into place.
So why use a set sun gear at all? ‘Fixed sun gears tend to be used in true servo applications,’ Greg Pennings, Ever-Power Customer Advocate, explained. ‘A set sun gear is essential when exact positioning and low backlash are an intrinsic part of the software.’ 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 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 have the ability to exceed the torque rankings of similar sized and larger sized parallel shaft reducers, and yet maintain a lower noise levels.
Sun, Ring and Planet
The most basic type of planetary gearset is demonstrated in the figures above. The figure at still left shows a three-dimensional watch while the figure at correct offers a cross-section. In this geartrain, inputs and result can be taken from the carrier, ring and sun gears, and only the earth experiences epicyclic motion. That is the many common kind of planetary gearset (with the exception of the differential) and it finds application in acceleration reducers and automatic transmissions. If you take aside a cordless drill, you’ll probably find this type of planetary gearset right behind the drill chuck.

Two Suns, Two Planets
The gearset proven above has two sunlight gears, and the two planet gears (the yellow gears) sun planet gear rotate as an individual unit. Sunlight gears (green and brownish) can rotate independently of 1 another. The inputs and output can be chosen from either sun gear 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 sun 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 – despite the fact that sunlight rotates counterclockwise in both instances.
The Differential
The gearset proven above is different from the preceding gearsets in that it is made up of miter gears instead of spur (or helical) gears. The ‘sun’ gears are those that do not go through the epicyclic movement experienced by the planet. And the differential can be utilized to measure the difference in rate between two shafts for the intended purpose of synchronization. In addition, the differential is often used in automotive drive trains to overcome the difference in wheel rate when a car encircles a corner.
