The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing provides been especially made to reach high torques that defeat the competition for units of the same size. All planetary carriers are produced as a cage created from solid materials. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water protection in accordance with protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears can be tighter tolerances, so all around the gear will be a tighter, more specific fit. And the tighter match means much less play in the gear teeth, which may be the cause of backlash in the first place. Of course, precision gears are more expensive, if the application demands high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to make sure the teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. For pre-loading, this can be done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between the gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for example, 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 ideals, the input stage is dimensionally smaller than the output stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and velocity accuracy is required. The flange output generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination with low backlash and high precision. Its robust, one-piece housing permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB line; the right angle shape makes the GSBL line the perfect match for all powerful applications where space is limited.
