The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also 
built 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 units of the same size. All planetary carriers are produced as a cage created from solid materials. This increases calm operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety relative to protection class IP65 in all lines.
One way to reduce backlash is by using precision gears. The focus on production in precision gears can be tighter tolerances, so all around the gear is a tighter, more precise fit. And the tighter fit means much less play in the gear teeth, which is the cause of backlash to begin with. Of program, precision gears are more costly, but if the application demands high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to ensure one’s teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. For pre-loading, this could be done using a spring mechanism to carry the gears firmly set up. This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity of backlash. So for instance, some gear types such as strain wave gears, or harmonic equipment drives, have zero backlash.
The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Because of the lower torque ideals, the input stage is definitely dimensionally smaller compared to the result stage. Its short style makes the GSD collection the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and acceleration accuracy is required. The flange result produces highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line means high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range provide same advantages as the GSB line; the right angle form makes the GSBL line the perfect match for all powerful applications where space is bound.
