Gear Sets for Commercial Vehicles
Ever-Power new planetary reducers employ a floating sun gear rather than a fixed position one.
The word ”There’s nothing new under the sun’ certainly applies to planetary reducers. And, while floating sunlight gears have already been around a long time, some engineers might not end up being aware of the benefits this unusual gear style can offer.
Traditionally, planetary reducers have used a set sun gear, where the centre gear is attached to 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 gear rather than a set 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 style engineer Scott Hulstein stated. ‘Because sunlight gear is in constant connection with the planets, it’s important that it’s properly centred among the three planets in order to provide equal load posting among itself and all three planets.’
Because of normal manufacturing tolerances however, a sun equipment which is securely set on a shaft will intermittently have more load on one planet equipment than on another gear Hulstein explained. ‘By allowing 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 benefits of this design. The floating sun gear provides ‘true involute actions,’ according to Hulstein. True involute action takes place when the rolling movement between your mating gears is as complete as feasible. The advantage of this total meshing of gears can be longer reducer lifestyle, since less internal gear slippage means fewer broken gear teeth.
That also means lower noise amounts. When sunlight 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 sound by allowing the sun gear to float into place.
So why make use of a set sun gear at all? ‘Fixed sun gears are often used in accurate servo applications,’ Greg Pennings, Ever-Power Customer Advocate, explained. ‘A fixed sun gear is necessary when exact positioning and low backlash are an intrinsic part of the app.’ Ever-Power engineers, however, were less concerned with low backlash and more interested with higher torque and/or lower noise applications.
Our planetary reducers with floating sun gears were made to compete with parallel shaft reducers, where backlash was less critical,’ Pennings said.
Utilizing 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 lesser noise levels.
Sun, Ring and Planet
The most basic kind of planetary gearset is proven in the figures above. The figure at still left shows a three-dimensional look at while 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 just the earth experiences epicyclic motion. This is the the sun planet gear majority of common type of planetary gearset (apart from the differential) and it discovers application in acceleration reducers and automatic transmissions. Invest the aside a cordless drill, you will most probably find this type 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 brown) can rotate independently of 1 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, nonetheless it can have problems with low efficiency if not really designed correctly.
Red sun input – purple sun fixed
Purple sun input – crimson sun fixed
The animations above show the ‘two suns – two planets’ gearset with one sun as input and the other sunlight fixed. Note that the carrier rotates clockwise in the animation at left and counterclockwise in the animation at right – even though sunlight rotates counterclockwise in both cases.
The gearset shown above is different from the preceding gearsets for the reason that it is made up of miter gears rather than spur (or helical) gears. The ‘sun’ gears are those that do not go through the epicyclic motion experienced by the planet. And the differential can be used to measure the difference in quickness between two shafts for the purpose of synchronization. In addition, the differential is often used in automotive drive trains to conquer the difference in wheel swiftness when a car encircles a corner.
