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 applies to planetary reducers. And, while floating sun gears have already been around a long time, some engineers might not be aware of the 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 into the shaft. When this set sun gear revolves, it turns the planet gears to create movement and/or power. Ever-Power new planetary reducers, however, are employing a floating sun gear rather than a set position sun gear.
Why a floating sunlight equipment? ‘In the planetary idea, the sun may be the driver, or pinion, in the apparatus set,’Ever-Power design engineer Scott Hulstein said. ‘Because the sun gear is in constant contact with the planets, it’s important that it is flawlessly centred among the three planets to be able to provide equal load posting among itself and all three planets.’
Because of normal manufacturing tolerances however, a sun gear which is securely fixed upon a shaft will intermittently have significantly more load using one planet equipment than on another equipment Hulstein explained. ‘By permitting the sun equipment 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 sunlight gear provides ‘true involute action,’ according to Hulstein. Accurate involute action happens when the rolling movement between the mating gears is as complete as feasible. The benefit of this finish meshing of gears is definitely longer reducer lifestyle, since less internal equipment slippage means fewer broken gear teeth.
That does mean lower noise levels. When the sun gear is permitted to completely roll into the world gears, there’s much 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 fixed sun gear at almost all? ‘Fixed sun gears are often used in true servo applications,’ Greg Pennings, Ever-Power Consumer Advocate, explained. ‘A set sun gear is necessary when specific positioning and low backlash are an integral part of the program.’ Ever-Power engineers, nevertheless, 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.
Utilizing the floating sun gear concept, the Ever-Power planetary reducers can easily 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 kind of planetary gearset is proven in the figures above. The figure at left shows a three-dimensional watch as the figure at right provides a cross-section. In this geartrain, inputs and result can be taken from the carrier, band and sunlight gears, and only the planet experiences epicyclic motion. This is the most common type of planetary gearset (with the exception of the differential) and it finds application in swiftness 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
Cross-sectional view
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. The sun gears (green and brownish) can rotate independently of 1 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 suffer from low efficiency if not designed correctly.

Purple sun input – red sun fixed
The animations above show the ‘two suns – two planets’ gearset with one sunlight as input and the other sunlight fixed. Remember that the carrier rotates clockwise in the animation at left 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 in that it is made up 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 acceleration between two shafts for the purpose of synchronization. In addition, the differential is frequently used in automotive drive trains to overcome the difference in wheel quickness when a car goes around a corner.
