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 provides been especially made to reach high torques that beat the competition for models of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases calm operating characteristics while at exactly the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water safety relative to protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears is tighter tolerances, so all over the gear will be a tighter, more exact fit. And 
the tighter match means much less play in the apparatus teeth, which may be the trigger of backlash in the first place. Of training course, precision gears are more costly, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure one’s teeth mesh tightly together. That is typically done by shortening the center distance between gears. For pre-loading, this could be done using a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity of backlash. So for example, some gear types such as stress 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. Due to the lower torque values, the input stage is usually dimensionally smaller compared to the result stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it the perfect fit for highly powerful applications where highest positioning and swiftness accuracy is necessary. The flange result creates highest torsional rigidity. For the lodging of especially 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 permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the GSB line; the right angle form makes the GSBL collection the perfect match for all powerful applications where space is bound.
