The high-end economy lines GSN & GFE combine high performance 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 offers been especially made to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases peaceful operating characteristics while at specifically the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water safety relative to protection course 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 match. And the tighter fit means much less play in the apparatus teeth, which is the trigger of backlash to begin with. Of training course, precision gears are more expensive, if the application calls for high accuracy, then precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to ensure the teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. As for pre-loading, this could be done using a spring mechanism to carry the gears firmly in place. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount of backlash. So for instance, some gear types such as stress wave gears, or harmonic gear 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 values, the insight stage is certainly dimensionally smaller than the result stage. Its short design makes the GSD series the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. The flange output generates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination 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 offer the 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.
