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 entire needle bearing provides been especially designed to reach high torques that defeat the competition for products of the same size. All planetary carriers are produced as a cage made from solid material. This increases tranquil operating characteristics while at exactly the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water security in accordance with protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all over the gear will be a tighter, more exact suit. And the tighter fit means much less play in the gear teeth, which may be the trigger of backlash in the first place. Of course, precision gears are more expensive, if the application calls for high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically done by shortening the guts distance between gears. For pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between the gear teeth and thus 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 gear 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 definitely dimensionally smaller than the output stage. Its short style makes the GSD line 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 quickness accuracy is required. The flange result creates highest torsional rigidity. For the accommodation of especially 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB range; the right angle form makes the GSBL collection an ideal match for all powerful applications where space is bound.
