Gear Sets for Industrial Vehicles

Ever-Power new planetary reducers hire a floating sun equipment rather than a fixed position one.
The word ”There’s nothing new beneath the sun’ certainly applies to planetary reducers. And, while floating sunlight gears have been around a long time, some engineers may not be aware of the benefits this unusual gear style can offer.
Traditionally, planetary reducers have used a fixed sun gear, where the centre gear is attached to or machined into 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 employing a floating sun gear rather than a fixed 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 style engineer Scott Hulstein said. ‘Because sunlight gear is in constant contact with the planets, it’s important that it is properly 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 on a shaft will intermittently have significantly more load using one planet gear than on another equipment Hulstein explained. ‘By enabling the sun gear to float, it centres itself among the three planets and produces continuous, 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 your mating gears is really as complete as possible. The advantage of this comprehensive meshing of gears can be longer reducer life, since less internal gear slippage means fewer broken gear teeth.
That does mean lower noise levels. When the sun gear is allowed 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 tend to be used in true servo applications,’ Greg Pennings, Ever-Power Consumer Advocate, explained. ‘A fixed sun gear is necessary when exact 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 sound applications.
Our planetary reducers with floating sunlight gears were made to compete with parallel shaft reducers, where backlash was less critical,’ Pennings said.
By using the floating sun gear concept, the Ever-Power planetary reducers are able to 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 shown in the figures above. The figure at remaining shows a three-dimensional watch while 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. That is the most common kind of planetary gearset (with the exception of the differential) and it discovers application in quickness reducers and automatic 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 demonstrated above has two sun gears, and the two planet gears (the yellow gears) rotate as an individual unit. The sun gears (green and dark brown) can rotate independently of 1 another. The inputs and output can be selected 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 – reddish 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 shown above is different from the preceding gearsets for the reason that it is composed of miter gears rather than spur (or helical) gears. The ‘sun’ gears are those that do not undergo the epicyclic motion experienced by the planet. And the differential can be utilized to measure the difference in swiftness between two shafts for the purpose of synchronization. In addition, the differential is often used in automotive drive trains to overcome the difference in wheel speed when a car goes around a corner.
