The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially made to reach high torques that defeat the competition for products of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water security in accordance with protection class IP65 in every lines.
One way to reduce backlash is by using precision gears. The focus on production in precision gears is tighter tolerances, so all over the gear is a tighter, more exact suit. And the tighter suit means less play in the apparatus teeth, which is the cause of backlash in the first place. Of course, precision gears are more costly, if the application calls for high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to make sure one’s teeth mesh tightly together. This is typically carried out by shortening the center distance between gears. As for pre-loading, this could be done using 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 can also have a huge 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. Because of the lower torque values, the input stage is dimensionally smaller compared to the output stage. Its short design makes the GSD collection the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and acceleration accuracy is necessary. The flange result generates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective 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 offer the same advantages as the GSB series; the right angle form makes the GSBL collection an ideal match for all powerful applications where space is limited.
