Gear Sets for Industrial Vehicles

Ever-Power new planetary reducers employ a floating sun equipment rather than a fixed position one.
The saying ”There’s nothing new under the sun’ certainly applies to planetary reducers. And, while floating sun gears have been around a long time, some engineers may not end up being aware of the benefits this unusual gear design can offer.
Traditionally, planetary reducers have used a fixed sun gear, where the centre gear is attached to or machined in to the shaft. When this fixed 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 equipment rather than a fixed position sun gear.
Why a floating sun equipment? ‘In the planetary idea, the sun is 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’s properly centred among the three planets to be able to provide equal load sharing among itself and all three planets.’
Due to normal manufacturing tolerances nevertheless, a sun gear which is securely fixed on a shaft will intermittently have significantly more load using one planet equipment than on another equipment Hulstein explained. ‘By enabling the sun equipment to float, it centres itself among the three planets and creates constant, equal load sharing.’
Equal load sharing is just one of the advantages of this design. The floating sunlight gear provides ‘true involute actions,’ according to Hulstein. True involute action takes place when the rolling motion between your mating gears is really as complete as possible. The benefit of this complete meshing of gears can be longer reducer existence, since less internal equipment slippage means fewer damaged gear teeth.
That does mean lower noise levels. When the sun 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 provides ‘designed out’ the apparatus mesh sound by allowing sunlight gear to float into place.
So why make use of a set sun gear at most? ‘Fixed sun gears tend to be used in accurate servo applications,’ Greg Pennings, Ever-Power Client Advocate, explained. ‘A set sun gear is necessary when specific positioning and low backlash are an intrinsic part of the software.’ 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 sun gears were made to compete with parallel shaft reducers, where backlash was less critical,’ Pennings said.
Utilizing the floating sun gear concept, the Ever-Power planetary reducers can exceed the torque rankings of similar sized and bigger sized parallel shaft reducers, 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 left shows a three-dimensional watch while the figure at right provides a sun planet gear cross-section. In this geartrain, inputs and output can be taken from the carrier, band and sun 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 speed reducers and automatic transmissions. If you take 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 both planet gears (the yellow gears) rotate as an individual unit. Sunlight gears (green and brown) can rotate independently of 1 another. The inputs and result can be chosen from either sun equipment and/or the carrier. High speed reductions may be accomplished with this unit, but it can have problems with low efficiency if not designed correctly.

The animations above show the ‘two suns – two planets’ gearset with one sunlight as input and the other sun fixed. Remember that the carrier rotates clockwise in the computer animation at left and counterclockwise in the animation at right – even though the sun rotates counterclockwise in both situations.
The Differential
The gearset demonstrated above is different from the preceding gearsets in 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 earth. And the differential can be used to gauge the difference in quickness between two shafts for the purpose of synchronization. In addition, the differential is often used in auto drive trains to overcome the difference in wheel rate when a car goes around a corner.
