We stock the quality Ever-Power gears that meet the needs of a range of commercial, industrial and military applications, both off-highway and on-highway. 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 could find rings and pinions with OE quality that are designed for toughness and reliability. Each set is manufactured to support your vehicle’s optimal performance. The ring and pinions are mated during production and temperature treated for the precise hardness your application demands. These important pieces of equipment keep your automobiles moving. When a repair or substitute is necessary, you can turn to Ever-power to provide the specific component sun planet gear required. The band and pinions we share are designed with the materials and procedures to meet OE specifications. As legitimate replacement gears, they’re produced to the same standards as the manufacturer’s parts. Compromising a part could mean compromising functionality. 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 employ a floating sun gear rather than a fixed position one.
The word ”There’s nothing new under the sun’ certainly applies to planetary reducers. And, while floating sunlight gears have been around quite a while, some engineers might not become aware of the huge benefits this unusual gear style can offer.
Traditionally, planetary reducers have used a set sun gear, where in fact the centre gear is mounted on or machined in to the shaft. When this set sun gear revolves, it turns the earth gears to create motion and/or power. Ever-Power new planetary reducers, however, are employing a floating sun equipment rather than a set 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 design engineer Scott Hulstein said. ‘Because sunlight gear is in constant connection with the planets, it’s important that it’s properly 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 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 allowing the sun gear to float, it centres itself among the three planets and generates continuous, equal load sharing.’
Equal load sharing is just one of the benefits of this design. The floating sunlight gear provides ‘true involute actions,’ according to Hulstein. Accurate involute action occurs when the rolling movement between the mating gears is as complete as possible. The advantage of this complete meshing of gears is usually longer reducer life, since less internal equipment slippage means fewer damaged gear teeth.
That does mean lower noise levels. When sunlight gear is permitted to completely roll in to the world gears, there’s less ‘rattling’ as the teeth mesh. In place, the Ever-Power product offers ‘designed out’ the apparatus mesh noise by allowing the sun equipment to float into place.
So why make use of a fixed sun gear at every? ‘Fixed sun gears tend to be used in true 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 program.’ 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 sunlight gears were designed to compete with parallel shaft reducers, where backlash was less critical,’ Pennings said.
Utilizing the floating sun equipment 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 lower noise levels.
Sun, Ring and Planet
The most basic kind of planetary gearset is demonstrated in the figures above. The figure at remaining 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 sun gears, and only the earth experiences epicyclic motion. That is the most common kind of planetary gearset (with the exception of the differential) and it discovers application in speed reducers and automatic transmissions. Invest the apart a cordless drill, you will most probably find this kind of planetary gearset directly behind the drill chuck.
Two Suns – Two Planets gearset

Two Suns, Two Planets
The gearset demonstrated above has two sun gears, and both planet gears (the yellow gears) rotate as an individual unit. The sun gears (green and dark brown) can rotate independently of one another. The inputs and output can be chosen from either sun equipment 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 sun fixed. Note that the carrier rotates clockwise in the animation at still left and counterclockwise in the computer animation at right – even though sunlight rotates counterclockwise in both situations.
The Differential
The gearset demonstrated 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 the ones that do not go through the epicyclic movement experienced by the earth. And the differential can be utilized to measure the difference in acceleration between two shafts for the intended purpose of synchronization. In addition, the differential is frequently used in auto drive trains to get over the difference in wheel swiftness when a car encircles a corner.
