The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing offers been especially designed to reach high torques that beat the competition for products of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases peaceful operating characteristics while at exactly the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water security in accordance with protection class IP65 in all lines.
One way to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears can be tighter tolerances, so all around the gear is a tighter, more precise match. And the tighter match means less play in the gear teeth, which is the trigger of backlash to begin with. Of training course, precision gears are more costly, if the application demands high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to ensure the teeth mesh tightly together. That is typically done by shortening the guts distance between gears. As for pre-loading, this could be done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge 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 ideals, the input stage is certainly dimensionally smaller than the result stage. Its short design makes the GSD series the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and swiftness accuracy is necessary. The flange result 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 stands for 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 range provide same advantages as the GSB range; the right angle shape makes the GSBL range the perfect match for all powerful applications where space is bound.
