The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing offers been especially designed to reach high torques that defeat the competition for systems of the same size. All planetary carriers are produced as a cage made from solid material. This increases calm operating characteristics while at exactly the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water protection relative to protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is usually tighter tolerances, so all over the gear is a tighter, more specific match. And the tighter fit means much less play in the gear teeth, which is the cause of backlash in the first place. Of program, precision gears are more expensive, if the application calls for high accuracy, then precision gearing may be the way to go.
From a gear design perspective, an easy way to reduce backlash is to make sure one’s teeth mesh tightly together. This is typically done by shortening the guts distance between gears. For pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount of backlash. So for instance, some gear types such as strain wave gears, or harmonic equipment drives, have zero backlash.

The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Due to the lower torque values, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and swiftness accuracy is required. The flange output generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB range; the right angle shape makes the GSBL series the perfect match for all powerful applications where space is bound.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-stage motors used with a single-phase AC power supply and three-phase motors used in combination with a three-phase AC power supply. A single-phase motor can be operated by simply zero backlash planetary gearbox connecting it to a single-phase power via the provided capacitor. A three-phase motor will not require a capacitor. All you have to is for connecting the motor right to a three-phase AC power supply.
The new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) along with the high-end economy GSN and GFE lines. Particularly ideal applications for the brand new range are those which place the best demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
