Gear Sets for Industrial Vehicles
Ever-Power new planetary reducers hire a floating sun gear rather than a set 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 become aware of the benefits this unusual gear style can offer.
Traditionally, planetary reducers possess used a fixed sun gear, where in fact the centre gear is attached to or machined into the shaft. When this fixed sun equipment revolves, it turns the planet gears to create movement and/or power. Ever-Power new planetary reducers, however, are having a floating sun gear rather than a fixed position sun gear.
Why a floating sunlight 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 constant connection with the planets, it’s important that it is perfectly centred among the three planets in order to provide equal load sharing among itself and all three planets.’
Due to normal manufacturing tolerances however, a sun gear which is securely set upon a shaft will intermittently have more load on one planet gear than on another equipment Hulstein explained. ‘By allowing the sun equipment to float, it centres itself among the three planets and generates continuous, equal load sharing.’
Equal load sharing is just one of the advantages of this design. The floating sunlight gear provides ‘accurate involute action,’ according to Hulstein. True involute action occurs when the rolling motion between the mating gears is really as complete as possible. The benefit of this full meshing of gears is longer reducer lifestyle, since less internal gear slippage means fewer broken gear teeth.
That also means lower noise levels. When the sun gear is allowed to completely roll in to the world gears, there’s less ‘rattling’ as the teeth mesh. In effect, the Ever-Power product has ‘designed out’ the gear 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 essential when precise positioning and low backlash are an intrinsic part of the application.’ 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 designed to compete with parallel shaft reducers, where backlash was less critical,’ Pennings said.
Utilizing the floating sun gear concept, the Ever-Power planetary reducers have the ability to exceed the torque rankings of similar sized and bigger sized parallel shaft reducers, yet maintain a lower noise levels.
Sun, Ring and Planet
The most basic type of planetary gearset is proven in the figures above. The figure at still left 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, band and sunlight gears, and only the earth experiences epicyclic motion. That is the the majority of common type of planetary gearset (with the exception of the differential) and it discovers application in velocity reducers and automatic transmissions. If you take aside a cordless drill, you’ll probably find this type of planetary gearset right behind the drill chuck.
Two Suns – Two Planets gearset
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 result can be selected from either sun equipment 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.
Reddish colored 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 remaining and counterclockwise in the animation at right – despite the fact that the sun rotates counterclockwise in both cases.
The gearset proven above differs from the preceding gearsets in that it is composed of miter gears instead of spur (or helical) gears. The ‘sun’ gears are the ones that do not undergo the epicyclic movement experienced by the earth. And the differential can be used to measure the difference in velocity between two shafts for the purpose of synchronization. Furthermore, the differential is frequently used in automotive drive trains to overcome the difference in wheel rate when a car goes around a corner.
