Gear Sets for Industrial Vehicles
Ever-Power new planetary reducers employ a floating sun gear rather than a set 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 be aware of the huge benefits this unusual gear design can offer.
Traditionally, planetary reducers possess used a set sun gear, where in fact the centre gear is mounted on or machined in to the shaft. When this set sun gear revolves, it turns the earth 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 sunlight equipment? ‘In the planetary concept, the sun may be the driver, or pinion, in the apparatus set,’Ever-Power design engineer Scott Hulstein said. ‘Because sunlight gear is in constant contact with the planets, it’s important that it’s perfectly 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 equipment which is securely set upon a shaft will intermittently have significantly more load using one planet gear than on another equipment Hulstein explained. ‘By allowing the sun gear to float, it centres itself among the three planets and produces constant, 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 as complete as possible. The benefit of this complete meshing of gears can be longer reducer lifestyle, since less internal equipment slippage means fewer damaged gear teeth.
That also means lower noise amounts. When sunlight gear is permitted to completely roll into the world gears, there’s much less ‘rattling’ as one’s teeth mesh. In place, the Ever-Power product provides ‘designed out’ the apparatus mesh noise by allowing sunlight gear to float into place.
So why use a set sun gear at every? ‘Fixed sun gears are often used in accurate servo applications,’ Greg Pennings, Ever-Power Consumer Advocate, explained. ‘A fixed sun gear is necessary when specific positioning and low backlash are an integral part of the app.’ Ever-Power engineers, nevertheless, 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 contend with parallel shaft reducers, where backlash was less critical,’ Pennings said.
Utilizing the floating sun equipment concept, the Ever-Power planetary reducers can easily 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 type of planetary gearset is shown in the figures above. The figure at remaining shows a three-dimensional view while the figure at right provides a cross-section. In this geartrain, inputs and output can be extracted from the carrier, ring and sunlight gears, and only the planet experiences epicyclic motion. That is the many 
common type of planetary gearset (with the exception of the differential) and it finds application in rate reducers and automated transmissions. Invest the apart a cordless drill, you’ll probably find this type of planetary gearset right behind the drill chuck.
Two Suns – Two Planets gearset
Cross-sectional view
Two Suns, Two Planets
The gearset shown above has two sun gears, and both planet gears (the yellow gears) rotate as an individual unit. The sun gears (green and brownish) can rotate independently of 1 another. The inputs and result can be selected 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.

Purple sun input – red 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 remaining and counterclockwise in the animation at right – despite the fact that the sun rotates counterclockwise in both situations.
The Differential
The gearset proven 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 the ones that do not undergo the epicyclic movement experienced by the planet. And the differential can be utilized to measure the difference in velocity between two shafts for the intended purpose of synchronization. Furthermore, the differential is often used in auto drive trains to conquer the difference in wheel acceleration when a car encircles a corner.
