The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing offers been especially made 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 tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water security relative to protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The focus on production in precision gears is certainly tighter tolerances, so all over the gear will be a tighter, more specific match. And the tighter match means much less play in the apparatus teeth, which may be the trigger of backlash to begin with. Of course, precision gears are more costly, if the application demands high accuracy, then precision gearing may be the way to go.
From a gear design perspective, a simple way to reduce backlash is to ensure the teeth mesh tightly together. That is typically completed by shortening the guts distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a huge impact on the amount of backlash. So for example, 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 can be dimensionally smaller than the output stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and quickness accuracy is necessary. The flange output creates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line means 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 line offer the same advantages as the GSB collection; the right angle shape makes the GSBL series the perfect match for all powerful applications where space is bound.
