Ever-Power High Precision Planetary Gearboxes
High precision Ever-Power planetary gearboxes are high quality gear units with a mixture of innovation and years of experience. Ever-Power planetary gearboxes are created to use servomotors in devices requiring high accuracy positioning.
The Ever-Power high precision planetary gearbox series ensures a minimum torsional backlash because of an extremely high torsional rigidity for the best precision and dynamics. Furthermore, the reinforced angular contact output bearingsoffer high radial and axial capacities, incredibly high level of resistance against tilt, perfect control precision and intensely low-noise running thanks to an optimized tooth profile.

Ever-Power series provides up to 12000 Nm high precision gearboxes
Ever-Power High Precision Planetary Gear units have the next advantages:
High capacity output bearing offers high radial and axial capacity and an extreme resistance against tilting moment thanks to the over-sized taper roller bearings.
High torsional rigidity thanks to an huge, robust, planet carrier with stable two-sided support for the planetary gears.
Maximum operating safety
Low running noise because of the optimized gear tooth profile
High efficiency (98%)
High quality seals offer long term sealing
Triple emergency stop torque
For intermittent and continuous operation
With 4 planet wheels assembled on the primary stage, Ever-Power high precision planetary gear units attain a very good load balancing, resulting in high operating safety and very smooth operation. The standard series includes 1, 2, 3 and 4 levels planetary gearboxes with ratios from 3 to 1000. Higher gear reductions can be attained by adding additional stages.
All of the torques you can ever need. Just imagine you skill with it.
Let’s speak about torque and precision. From many years Ever-Power high precision planetary gearboxes are popular brand for high precision gearboxes with high torque values. Even though many manufacturers stop the typical range in about 1000 Nm, we produce heavy-load high precision planetary gearboxes with up to 12000 Nm for big machines that require high accuracy positioning combined with a high value of torque transmitting. However if you need more torque, Ever-Power also offers heavy-load precision gearboxes series that allow torques up to 16000 Nm (SGH).
The largest Backlash range. Purchase what you need, no more.
Frequently customers ask us “I need a robust precision planetary gearbox yet I don’t really want to pay a price for <3 arcmin gearbox, because 10 arcmin is enough for the device...”. We have the solution. Ever-Power supplies the biggest range of backlash for his or her customers, ca.0' <1' <3' <5' or <10'. Just pay for what you need
Unmatched torsional stiffness. Effective and market-leading machines
There are plenty of planetary gearboxes on the market with compatible output dimensions. Therefore, you count yourself lucky because you can choose among many brands, right? But if you produce high precision devices and you are searching for a kick-ass high precision planetary gearbox, after that it is not very easy. Ever-Power Ever-Power planetary gearboxes are created for the highest torsional rigidity. Why? Because torsional backlash generally is the main component of the total backlash when the engine is running at complete load. Therefore we did a hand and hand comparison between a typical model Ever-Power and the best alternatives. Ever-Power arrived ahead, and not by chance. Ever-Power supplies the planetary gearbox (with result shaft) with the best torsional stiffness. Ever-Power gearboxes are more specific and that offer greater results even (and specially) in high-dynamic situations.
Transmitting Ratios. World’s biggest range
Our customers create many types of machines. Thus we offer the biggest range of transmitting ratios in the world. Thus, our customer can optimize their machine properly.
For ratios 4 to 1000, Ever-Power delivers. You can trust Ever-Power to have their clients needs in the front line.
High capacity output bearings
All Ever-Power high precision planetary gearboxes are made to offer the maximum capacity at the result shaft. So, we’ve designed the Ever-Power gearboxes with a single-piece huge diameter output shaft – planet carrier. We utilized the biggest high performance taper roller bearings acquiring the highest torsional rigidity. We are proud to announce that the Ever-Power high precision planetary gearboxes offer the best accuracy and output capacity for machines with a big number of cycles each and every minute. From today’s packaging machine to a strong NC tool machine, Ever-Power is the perfect solution.
Efficiency
A precision design, ultra restricted tolerance machining and great surface finishes, enable the Ever-Power to operate at high efficiency values, 98% for one stage gearbox and 96% for a two phases gearbox. Efficiency values rely on torsional backlash, rate, ratio, ambient temperature, etc. The common efficiency level varies based on the number of levels as proven in the specialized data sheets for every gearbox model.
Lubrication
All SG high precision gearboxes are given a particular synthetic lubricant that provides lifetime lubrication.
Gears, world carrier and housing
The ring gear, manufactured from steel, is an integral area of the housing, sunlight and world wheels are made of contemporary treated steels, and the input bearing flange is made from aluminum. The one piece world carrier and output shaft is constructed of ductile iron, resulting a robust style.
Design and mounting positions
Ever-Power high precision planetary gear units usually have an square result flange with holes and will be mounted in virtually any position. Nevertheless, on demand, we can also supply gearboxes with round result flanges with threaded holes.
Motor connection
The motor installation is quite easy thanks to clamping ring technology, that ensures a slip free and non wearing transmission. This reliable insight coupling system is ideal for continuous and intermittent support with even shaft servomotors.
Low noise operation
This series provides high efficiency and low running noise because of high gearing quality, optimized gear profile, uncaged needle bearings for the earth gears and high quality synthetic lubricant.
