The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing offers been especially designed to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases silent operating characteristics while at exactly the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water protection relative to protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The concentrate on production in precision gears is usually tighter tolerances, so all over the gear will be a tighter, more specific fit. And the tighter fit means much less play in the gear teeth, which may be the cause of backlash in the first place. Of program, precision gears are more costly, but if the application demands high accuracy, then precision gearing could 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. For pre-loading, this can be done using a spring mechanism to hold the gears firmly in place. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may 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 ideals, the input stage is usually dimensionally smaller than the result stage. Its short style makes the GSD line the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and rate accuracy is necessary. The flange output creates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available 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 provide same advantages as the GSB series; the right angle form makes the GSBL series the perfect match for all powerful applications where space is bound.
