Gear Sets for Industrial Vehicles
Ever-Power new planetary reducers hire a floating sun gear 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 huge benefits this unusual gear style can offer.
Traditionally, planetary reducers possess used a set sun gear, where the centre gear is mounted on or machined in to the shaft. When this set sun gear revolves, it turns the planet gears to create movement 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 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 is perfectly centred among the three planets in order to provide equal load sharing among itself and all three planets.’
Because of normal manufacturing tolerances however, a sun gear which is securely fixed on a shaft will intermittently have more load on one planet equipment than on another equipment Hulstein explained. ‘By allowing the sun equipment to float, it centres itself among the three planets and creates continuous, equal load sharing.’
Equal load sharing is just one of the benefits of this design. The floating sun gear provides ‘accurate involute actions,’ according to Hulstein. Accurate involute action happens when the rolling motion between the mating gears is really as complete as possible. The benefit of this full meshing of gears is usually longer reducer life, since less internal gear slippage means fewer damaged gear teeth.
That does mean lower noise levels. When the sun gear is permitted to completely roll into the world 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 the sun gear to float into place.
So why use a set sun gear at almost all? ‘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 precise positioning and low backlash are an intrinsic part of the program.’ Ever-Power engineers, nevertheless, were less concerned with low backlash and more interested with higher torque and/or lower noise applications.
Our planetary reducers with floating sunlight gears were made 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 can easily 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 left shows a three-dimensional view while the figure at correct provides a cross-section. In this geartrain, inputs and output can be taken from the carrier, ring and sun gears, and only the earth experiences epicyclic motion. This 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 apart a cordless drill, you will most probably find this type of planetary gearset right behind the drill chuck.
Two Suns – Two Planets gearset
Cross-sectional view
Two Suns, Two Planets
The gearset shown above has two sun gears, and both planet gears (the yellow gears) rotate as an individual unit. The sun gears (green and brownish) can rotate independently of 1 another. The inputs and result can be selected 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.
Reddish sun input – purple sun fixed
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. Remember that the carrier rotates clockwise in the computer animation at left and counterclockwise in the animation at right – despite the fact that sunlight rotates counterclockwise in both situations.
The Differential
The gearset shown above differs from the preceding gearsets in that it is made up of miter gears rather than 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 gauge the difference in acceleration 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.
