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 beneath the sun’ certainly pertains to planetary reducers. And, while floating sunlight gears have been around a long time, some engineers may not become aware of the huge benefits this unusual gear style can offer.
Traditionally, planetary reducers possess used a set sun gear, where the centre gear is attached to or machined in to the shaft. When this fixed sun gear revolves, it turns the planet gears to create movement and/or power. Ever-Power new planetary reducers, however, are having a floating sun equipment rather than a set position sun gear.
Why a floating sun gear? ‘In the planetary concept, the sun is the driver, or pinion, in the apparatus set,’Ever-Power style engineer Scott Hulstein said. ‘Because sunlight gear is in continuous contact with the planets, it’s important that it’s flawlessly 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 fixed upon a shaft will intermittently have more load using one planet gear than on another equipment Hulstein explained. ‘By allowing the sun equipment to float, it centres itself among the three planets and creates 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 movement between your mating gears is as complete as possible. The benefit of this finish meshing of gears can be longer reducer life, since less internal gear slippage means fewer damaged gear teeth.
That also means lower noise levels. When sunlight gear is allowed to completely roll in to the world gears, there’s much less ‘rattling’ as one’s teeth mesh. In place, the Ever-Power product offers ‘designed out’ the apparatus mesh sound by allowing the sun equipment to float into place.
So why make use of a fixed sun gear at every? ‘Fixed sun gears tend to be used in accurate servo applications,’ Greg Pennings, Ever-Power Customer Advocate, explained. ‘A set sun gear is necessary when precise positioning and low backlash are an integral part of the app.’ 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.
Utilizing the floating sun equipment concept, the Ever-Power planetary reducers have the ability to exceed the torque ratings of similar sized and larger sized parallel shaft reducers, 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 remaining shows a three-dimensional watch while the figure at correct offers a cross-section. In this geartrain, inputs and result can be taken from the carrier, ring and sunlight gears, and only the planet experiences epicyclic motion. That is the the majority of common kind of planetary gearset (with the exception of the differential) and it finds application in rate reducers and automatic transmissions. Invest the apart 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 shown above has two sun gears, and both planet gears (the yellow gears) rotate as an individual unit. Sunlight gears (green and brown) can rotate independently of one another. The inputs and output can be selected from either sun gear and/or the carrier. High speed reductions may be accomplished with this unit, nonetheless it can have problems with low efficiency if not designed correctly.
Crimson sun input – purple sun fixed
Purple sun input – red sun fixed
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 sun planet gear computer animation at left and counterclockwise in the computer animation at right – despite the fact that the sun rotates counterclockwise in both cases.
The gearset demonstrated 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 earth. And the differential can be used to gauge the difference in quickness between two shafts for the purpose of synchronization. Furthermore, the differential is often used in auto drive trains to overcome the difference in wheel acceleration when a car goes around a corner.
