Gear Sets for Industrial Vehicles
Ever-Power new planetary reducers employ a floating sun gear rather than a fixed position one.
The saying ”There’s nothing new under the sun’ certainly applies to planetary reducers. And, while floating sunlight gears have already been around quite a while, some engineers might not end up being aware of the huge benefits this unusual gear design can offer.
Traditionally, planetary reducers have used a fixed 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 motion and/or power. Ever-Power new planetary reducers, however, are employing 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 apparatus set,’Ever-Power style engineer Scott Hulstein said. ‘Because the sun gear is in continuous contact with the planets, it’s important that it’s perfectly centred among the three planets to be able to provide equal load posting 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 more load using one planet gear than on another gear Hulstein explained. ‘By permitting the sun gear 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 action,’ according to Hulstein. Accurate involute action happens when the rolling motion between the mating gears is really as complete as feasible. The advantage of this total meshing of gears is usually longer reducer life, since less internal gear slippage means fewer broken gear teeth.
That also means lower noise levels. When the sun gear is permitted to completely roll into the planet gears, there’s less ‘rattling’ as the teeth mesh. In effect, the Ever-Power product has ‘designed out’ the apparatus mesh noise by allowing sunlight equipment to float into place.
So why use a fixed sun gear at most? ‘Fixed sun gears are often used in true servo applications,’ Greg Pennings, Ever-Power Client Advocate, explained. ‘A set sun gear is necessary when exact positioning and low backlash are an integral part of the application.’ Ever-Power engineers, nevertheless, were less worried about low backlash and more interested with higher torque and/or lower sound applications.
Our planetary reducers with floating sunlight gears were made to contend with parallel shaft reducers, where backlash was less critical,’ Pennings said.
Utilizing the floating sun gear concept, the Ever-Power planetary reducers have the ability to exceed the torque ratings 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 proven in the figures above. The figure at remaining shows a three-dimensional watch as the figure at correct provides a cross-section. In this geartrain, inputs and output can be taken from the carrier, band and sunlight gears, and only the planet experiences epicyclic motion. This is the the majority of common kind of planetary gearset (apart from the differential) and it discovers application in speed reducers and automatic transmissions. If you take aside a cordless drill, you will most probably find this kind of planetary gearset directly behind the drill chuck.
Two Suns – Two Planets gearset
Two Suns, Two Planets
The gearset demonstrated above has two sun gears, and the two planet gears (the yellow gears) rotate as a single unit. Sunlight gears (green and brownish) can rotate independently of one another. The inputs and output can be chosen from either sun equipment and/or the carrier. Very high speed reductions may be accomplished with this unit, but it can suffer from low efficiency if not really designed correctly.
Reddish colored sun input – purple sun fixed
Purple sun input – reddish sun fixed
The animations above show the ‘two suns – two planets’ gearset with one sunlight as input and the other sunlight fixed. Note that the carrier rotates clockwise in the computer animation at still left and counterclockwise in the computer animation at right – even though the sun rotates counterclockwise in both cases.
The gearset demonstrated above is different 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 undergo the epicyclic motion experienced by the earth. And the differential can be utilized to gauge the difference in rate between two shafts for the purpose of synchronization. Furthermore, the differential is often used in auto drive trains to overcome the difference in wheel velocity when a car goes around a corner.
