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 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 precision and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water security in accordance with protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is tighter tolerances, so all around the gear will be a tighter, more exact suit. And the tighter suit means less play in the gear teeth, which is the cause of backlash to begin with. Of training course, precision gears are more expensive, but 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 make sure the teeth mesh tightly together. That is typically performed by shortening the center distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used can 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, 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 values, the input stage is certainly dimensionally smaller than the output stage. Its short style makes the GSD collection the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and acceleration accuracy is necessary. The flange result produces 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 stands for 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 collection offer the same advantages as the GSB collection; the right angle shape makes the GSBL collection the perfect match for all powerful applications where space is limited.
