The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped 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 defeat the competition for models of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases peaceful operating characteristics while at precisely 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 method to reduce backlash is to use precision gears. The concentrate on production in precision gears is definitely tighter tolerances, therefore all over the gear is a tighter, more exact match. And the tighter match means much less play in the gear teeth, which is the trigger of backlash to begin with. Of training course, precision gears are more expensive, if the application demands high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically done by shortening the center distance between gears. As for pre-loading, this could be done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the play 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 instance, some equipment types such as strain wave gears, or harmonic equipment 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 values, the input stage is certainly dimensionally smaller compared to the result stage. Its short design makes the GSD series the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and swiftness accuracy is required. The flange output creates 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 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 provide same advantages as the GSB range; the right angle shape makes the GSBL collection the perfect match for all powerful applications where space is bound.
