The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing provides been especially made to reach high torques that beat the competition for devices of the same size. All planetary carriers are produced as a cage created from solid material. This increases quiet operating characteristics while at exactly the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water safety in accordance with protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is tighter tolerances, so all over the gear is a tighter, more exact match. And the tighter suit means less play in the apparatus teeth, which is the trigger of backlash in the first place. Of program, precision gears are more expensive, but if the application demands high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically 
done by shortening the center distance between gears. For pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity 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. Due to the lower torque values, the input stage is certainly dimensionally smaller than the result stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it an ideal fit for highly dynamic applications where highest positioning and rate accuracy is required. 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 more. 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 range provide same advantages as the GSB series; the right angle shape makes the GSBL collection the perfect match for all powerful applications where space is limited.
