The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing offers been especially made to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water safety relative to protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is usually tighter tolerances, so all around the gear will be a tighter, more precise match. And the tighter suit means less play in the gear teeth, which may be the cause of backlash in the first place. Of course, precision gears are more costly, but if the application demands high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to make sure one’s teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. As 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 type of gears used can also have a huge impact on the amount of backlash. So for instance, some gear types such as stress 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. Because of the lower torque ideals, the input stage is usually dimensionally smaller compared to the result stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange output generates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line means high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series offer the same advantages as the GSB series; the right angle shape makes the GSBL range an ideal match for all powerful applications where space is bound.
