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 under the sun’ certainly applies to planetary reducers. And, while floating sunlight gears have been around a long time, some engineers may not become aware of the benefits this unusual gear design can offer.
Traditionally, planetary reducers have used a set sun gear, where the centre gear is mounted on or machined into the shaft. When this fixed sun equipment revolves, it turns the planet gears to create movement 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 gear? ‘In the planetary idea, the sun is the driver, or pinion, in the apparatus set,’Ever-Power design engineer Scott Hulstein stated. ‘Because sunlight gear is in continuous contact with the planets, it’s important that it is flawlessly centred among the three planets to be able to provide equal load posting among itself and all three planets.’
Due to normal manufacturing tolerances however, a sun gear which is securely set upon a shaft will intermittently have more load using one planet gear than on another gear 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 sun gear provides ‘true involute actions,’ according to Hulstein. True involute action occurs when the rolling motion between your mating gears is really as complete as possible. The advantage of this total meshing of gears is longer reducer lifestyle, since less internal gear slippage means fewer broken gear teeth.
That does mean lower noise levels. When sunlight gear is permitted to completely roll in to the planet gears, there’s much less ‘rattling’ as the teeth mesh. In effect, the Ever-Power product offers ‘designed out’ the gear mesh noise by allowing sunlight gear to float into place.
So why make use of a fixed sun gear at sun planet gear almost all? ‘Fixed sun gears tend to be used in true servo applications,’ Greg Pennings, Ever-Power Client Advocate, explained. ‘A fixed sun gear is essential when specific positioning and low backlash are an integral part of the program.’ Ever-Power engineers, however, 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 contend with parallel shaft reducers, where backlash was less critical,’ Pennings said.
By using the floating sun equipment concept, the Ever-Power planetary reducers are able 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 kind of planetary gearset is shown in the figures above. The figure at left shows a three-dimensional view while the figure at correct offers a cross-section. In this geartrain, inputs and result 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 (apart from the differential) and it discovers application in quickness reducers and automated transmissions. If you take 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 both planet gears (the yellow gears) rotate as an individual unit. The sun gears (green and brown) 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 have problems with low efficiency if not designed correctly.

Purple sun input – reddish sun fixed
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 still left and counterclockwise in the animation at right – even though the sun rotates counterclockwise in both situations.
The Differential
The gearset shown 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 those that do not undergo the epicyclic motion experienced by the planet. And the differential can be utilized to gauge the difference in velocity between two shafts for the purpose of synchronization. Furthermore, the differential is often used in automotive drive trains to conquer the difference in wheel rate when a car goes around a corner.
