The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing offers been especially designed to reach high torques that beat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt 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 definitely tighter tolerances, so all over the gear will be a tighter, more exact fit. And the tighter fit means less play in the gear teeth, which may be the trigger of backlash to begin with. Of training course, precision gears are more costly, but if the application demands high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically done by shortening the guts distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the amount of backlash. So for instance, some equipment types such as strain 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. Due to the lower torque ideals, the input stage is certainly dimensionally smaller compared to the output stage. Its short style makes the GSD line the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is required. The flange output generates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line means high performance in combination 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 collection offer the same advantages as the GSB series; the right angle form makes the GSBL series an ideal match for all powerful applications where space is bound.
