Gear Sets for Industrial Vehicles

Ever-Power new planetary reducers hire a floating sun gear rather than a set position one.
The saying ”There’s nothing new beneath the sun’ certainly applies to planetary reducers. And, while floating sun gears have already been around a long time, some engineers may not be aware of the huge benefits this unusual gear style can offer.
Traditionally, planetary reducers have used a set sun gear, where in fact 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 movement and/or power. Ever-Power new planetary reducers, however, are having a floating sun gear rather than a set position sun gear.
Why a floating sun equipment? ‘In the planetary concept, the sun may be the driver, or pinion, in the apparatus set,’Ever-Power design engineer Scott Hulstein said. ‘Because the sun gear is in continuous connection 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 set on a shaft will intermittently have significantly more load using one planet equipment than on another equipment Hulstein explained. ‘By allowing the sun equipment 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. True involute action takes place when the rolling movement between your mating gears is as complete as feasible. The benefit of this full meshing of gears can be longer reducer existence, since less internal equipment slippage means fewer broken gear teeth.
That does mean lower noise levels. When sunlight gear is permitted to completely roll in to the world gears, there’s much less ‘rattling’ as the teeth mesh. In place, the Ever-Power product has ‘designed out’ the gear mesh noise by allowing sunlight equipment to float into place.
So why make use of a fixed sun gear at almost all? ‘Fixed sun gears are often used in accurate servo applications,’ Greg Pennings, Ever-Power Client Advocate, explained. ‘A fixed sun gear is necessary when specific positioning and low backlash are an integral part of the program.’ Ever-Power engineers, however, were less concerned with 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, yet maintain a lesser noise levels.
Sun, Ring and Planet
The most basic kind of planetary gearset is shown in the figures above. The figure at left shows a three-dimensional watch while the figure at correct offers a cross-section. In this geartrain, inputs and output can be extracted from the carrier, band and sun gears, and just the earth experiences epicyclic motion. This is the the majority of common kind of planetary gearset (with the exception of the differential) and it discovers application in acceleration reducers and automatic transmissions. Invest the aside a cordless drill, you’ll probably find this kind of planetary gearset right behind the drill chuck.
Two Suns – Two Planets gearset
Cross-sectional view
Two Suns, Two Planets
The gearset proven above has two sunlight gears, and the two planet gears (the yellow gears) rotate as an individual unit. The sun gears (green and dark brown) can rotate independently of one 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 have problems with 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 remaining and counterclockwise in the animation at right – despite the fact that sunlight rotates counterclockwise in both instances.
The Differential
The gearset proven above differs from the preceding gearsets in that it is composed of miter gears rather than spur (or helical) gears. The ‘sun’ gears are those that do not undergo 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 automotive drive trains to overcome the difference in wheel swiftness when a car goes around a corner.
