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 has been especially made to reach high torques that beat the competition for systems of the same size. All planetary carriers are produced as a cage made from solid material. This increases noiseless operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water security in accordance with protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is certainly tighter tolerances, therefore all over the gear is a tighter, more exact match. And the tighter match means less play in the gear teeth, which is the trigger of backlash in the first place. Of training course, precision gears are more costly, but if the application demands high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to ensure one’s teeth mesh tightly together. This is typically done by shortening the guts distance between gears. For pre-loading, this is often done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the amount of backlash. So for example, some equipment types such as stress wave gears, or harmonic gear drives, possess 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 insight stage is certainly dimensionally smaller compared to the result stage. Its short style makes the GSD collection the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it an ideal fit for highly powerful applications where highest positioning and velocity accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation of particularly 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the GSB range; the right angle form makes the GSBL collection the perfect match for all powerful applications where space is limited.
