The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially designed to reach high torques that defeat the competition for units of the same size. All planetary carriers are produced as a cage made from solid materials. This increases silent operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water security in accordance with protection class IP65 in all lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all around the gear will be a tighter, more precise suit. And the tighter fit means much less play in the gear teeth, which is the trigger of backlash in the first place. Of training course, precision gears are more expensive, if the application calls for high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to make sure one’s teeth mesh tightly together. That is typically performed by shortening the center distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the play between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the amount of backlash. So for example, some equipment types such as strain wave gears, or harmonic equipment drives, possess 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 usually dimensionally smaller compared to the result stage. Its short style makes the GSD line the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and speed accuracy is necessary. The flange result generates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in mixture 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 series the perfect match for all dynamic applications where space is limited.
