Our Gears inventory features the ring and pinion product line from Ever-Power. They are essential parts in your stock of carrier components. At Ever-Power, you will find rings and pinions with OE quality that are designed for strength and reliability. Each established is manufactured to aid your vehicle’s optimized performance. The band and pinions are mated during production and high temperature treated for the exact hardness the application demands. These important pieces of equipment keep your automobiles moving. Whenever a repair or alternative is required, you can turn to Ever-power to provide the exact component required. The band and pinions we share are built with the components and procedures to meet up OE specifications. As genuine replacement gears, they’re produced to the same criteria as the manufacturer’s parts. Compromising a component could mean compromising efficiency. And there’s no need to do that when you’re able to look to our extensive gear inventory.
Gear Sets for Commercial Vehicles

Ever-Power new planetary reducers hire a floating sun equipment rather than a set position one.
The saying ”There’s nothing new under the sun’ certainly pertains to planetary reducers. And, while floating sunlight gears have already been around a long time, some engineers may not become aware of the huge benefits this unusual gear style can offer.
Traditionally, planetary reducers possess used a set sun gear, where the centre gear is mounted on or machined in to the shaft. When this fixed 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 fixed position sun gear.
Why a floating sunlight gear? ‘In the planetary concept, the sun is the driver, or pinion, in the gear set,’Ever-Power style engineer Scott Hulstein said. ‘Because sunlight gear is in constant connection with the planets, it’s important that it’s flawlessly centred among the three planets in order to provide equal load posting among itself and all three planets.’
Because of normal manufacturing tolerances however, a sun equipment which is securely set upon a shaft will intermittently have significantly more load on one planet gear than on another equipment Hulstein explained. ‘By enabling the sun gear to float, it centres itself among the three planets and generates constant, equal load sharing.’
Equal load sharing is just one of the benefits of this design. The floating sunlight gear provides ‘accurate involute action,’ according to Hulstein. True involute action takes place when the rolling movement between the mating gears is really as complete as possible. The benefit of this complete meshing of gears is usually longer reducer life, since less internal equipment slippage means fewer broken gear teeth.
That also means lower noise levels. When the sun gear is allowed to completely roll in to the planet gears, there’s much less ‘rattling’ as one’s teeth mesh. In effect, the Ever-Power product has ‘designed out’ the apparatus mesh sound by allowing sunlight equipment to float into place.
So why make use of a set sun gear at most? ‘Fixed sun gears are often used in accurate servo applications,’ Greg Pennings, Ever-Power Customer Advocate, explained. ‘A fixed sun gear is necessary when specific positioning and low backlash are an intrinsic 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 gear concept, the Ever-Power planetary reducers have the ability to exceed the torque rankings of similar sized and bigger sized parallel shaft reducers, and yet maintain a lesser noise levels.
Sun, Ring and Planet
The most basic kind of planetary sun planet gear gearset is demonstrated in the figures above. The figure at remaining shows a three-dimensional watch while the figure at right offers a cross-section. In this geartrain, inputs and output can be extracted from the carrier, band and sunlight gears, and only the earth experiences epicyclic motion. That is the many common type of planetary gearset (apart from the differential) and it finds application in quickness reducers and automatic transmissions. If you take apart a cordless drill, you’ll probably find this kind 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 an individual unit. Sunlight gears (green and brown) can rotate independently of one another. The inputs and result can be selected from either sun gear and/or the carrier. High speed reductions can be achieved with this unit, nonetheless it can suffer from low efficiency if not designed correctly.

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 still left and counterclockwise in the computer animation at right – despite the fact that the sun rotates counterclockwise in both cases.
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 motion experienced by the earth. And the differential can be used to measure the difference in velocity between two shafts for the purpose of synchronization. In addition, the differential is frequently used in auto drive trains to overcome the difference in wheel rate when a car encircles a corner.
