Gear Sets for Commercial Vehicles

Ever-Power new planetary reducers hire a floating sun equipment rather than a set position one.
The word ”There’s nothing new under the sun’ certainly pertains to planetary reducers. And, while floating sun gears have been around quite a while, some engineers might not become aware of the benefits this unusual gear style can offer.
Traditionally, planetary reducers have used a set sun gear, where the centre gear is mounted on or machined into the shaft. When this fixed sun equipment revolves, it turns the earth gears to create motion and/or power. Ever-Power new planetary reducers, however, are having a floating sun equipment 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 gear set,’Ever-Power design engineer Scott Hulstein stated. ‘Because the sun gear is in constant connection with the planets, it’s important that it is properly centred among the three planets in order to provide equal load posting among itself and all three planets.’
Because of normal manufacturing tolerances nevertheless, a sun equipment which is securely fixed upon a shaft will intermittently have significantly more load on one planet equipment than on another gear Hulstein explained. ‘By allowing the sun gear to float, it centres itself among the three planets and produces continuous, equal load sharing.’
Equal load posting is just one of the benefits of this design. The floating sun gear provides ‘accurate involute action,’ according to Hulstein. Accurate involute action occurs when the rolling movement between your mating gears is as complete as feasible. The benefit of this comprehensive meshing of gears is certainly longer reducer lifestyle, since less internal equipment slippage means fewer sun planet gear damaged gear teeth.
That does mean lower noise levels. When sunlight gear is allowed to completely roll in to the planet gears, there’s much less ‘rattling’ as one’s teeth mesh. In place, the Ever-Power product provides ‘designed out’ the gear mesh sound by allowing the sun gear to float into place.
So why make use of a set sun gear at all? ‘Fixed sun gears tend to be used in accurate servo applications,’ Greg Pennings, Ever-Power Customer Advocate, explained. ‘A fixed sun gear is essential when specific positioning and low backlash are an intrinsic part of the software.’ Ever-Power engineers, nevertheless, were less concerned with low backlash and more interested with higher torque and/or lower sound applications.
Our planetary reducers with floating sunlight 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 are able 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 demonstrated in the figures above. The figure at still left shows a three-dimensional look at while the figure at right offers a cross-section. In this geartrain, inputs and result can be extracted from the carrier, ring and sun gears, and just the earth experiences epicyclic motion. That is the most common kind of planetary gearset (apart from the differential) and it finds application in swiftness reducers and automated 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
Cross-sectional view
Two Suns, Two Planets
The gearset shown above has two sunlight gears, and both planet gears (the yellow gears) rotate as an individual unit. Sunlight 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. Very 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 sunlight fixed. Note that the carrier rotates clockwise in the animation at remaining and counterclockwise in the computer animation at right – despite the fact that sunlight rotates counterclockwise in both situations.
The Differential
The gearset shown above differs from the preceding gearsets for the reason that it is composed of miter gears instead of spur (or helical) gears. The ‘sun’ gears are those that do not go through the epicyclic movement experienced by the planet. And the differential can be utilized to measure the difference in speed between two shafts for the intended purpose of synchronization. In addition, the differential is frequently used in automotive drive trains to get over the difference in wheel acceleration when a car goes around a corner.
