Gear Sets for Industrial Vehicles

Ever-Power new planetary sun planet gear reducers employ a floating sun gear rather than a set position one.
The word ”There’s nothing new under the sun’ certainly pertains to planetary reducers. And, while floating sun gears have already been around quite a while, some engineers might not become aware of the benefits this unusual gear design can offer.
Traditionally, planetary reducers have used a set sun gear, where in fact the centre gear is mounted on or machined into the shaft. When this fixed sun gear revolves, it turns the planet gears to create motion and/or power. Ever-Power new planetary reducers, however, are having a floating sun equipment rather than a fixed position sun gear.
Why a floating sunlight 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 connection with the planets, it’s important that it’s perfectly 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 more load using one planet equipment than on another gear Hulstein explained. ‘By permitting the sun equipment to float, it centres itself among the three planets and generates continuous, equal load sharing.’
Equal load sharing is merely one of the benefits of this design. The floating sunlight gear provides ‘true involute action,’ according to Hulstein. True involute action happens when the rolling motion between your mating gears is as complete as feasible. The advantage of this finish meshing of gears is certainly longer reducer life, since less internal gear slippage means fewer damaged gear teeth.
That does mean lower noise amounts. When the sun gear is allowed to completely roll in to 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 the sun gear to float into place.
So why use a fixed sun gear at all? ‘Fixed sun gears are often used in true servo applications,’ Greg Pennings, Ever-Power Consumer Advocate, explained. ‘A fixed sun gear is necessary when precise positioning and low backlash are an integral 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 sunlight gears were made 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 can exceed the torque ratings of similar sized and bigger sized parallel shaft reducers, yet maintain a lower noise levels.
Sun, Ring and Planet
The most basic type of planetary gearset is shown in the figures above. The figure at left shows a three-dimensional watch as the figure at right offers a cross-section. In this geartrain, inputs and output can be extracted from the carrier, ring and sun gears, and just the planet experiences epicyclic motion. This is the most common kind of planetary gearset (apart from the differential) and it finds application in swiftness reducers and automated transmissions. If you take aside a cordless drill, you’ll probably find this kind of planetary gearset directly behind the drill chuck.
Two Suns – Two Planets gearset

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 result can be chosen from either sun gear and/or the carrier. Very high speed reductions can be achieved with this unit, nonetheless 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 sun fixed. Note that the carrier rotates clockwise in the animation at remaining and counterclockwise in the animation at right – even though sunlight rotates counterclockwise in both situations.
The Differential
The gearset demonstrated above is different from the preceding gearsets for the reason 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 utilized to gauge the difference in speed between two shafts for the purpose of synchronization. Furthermore, the differential is frequently used in automotive drive trains to get over the difference in wheel velocity when a car goes around a corner.
