The high-end economy lines GSN & GFE combine high performance with financial 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 designed to reach high torques that defeat the competition for devices of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water protection in accordance with protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is usually tighter tolerances, so all around the gear is a tighter, more exact suit. And the tighter match means much less play in the apparatus teeth, which may be the cause of backlash in the first place. Of program, precision gears are more costly, if the application calls for high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. This is typically performed by shortening the center distance between gears. For pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the play between the gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a huge impact on the quantity of backlash. So for example, some equipment 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. Due to the lower torque values, the input stage can be dimensionally smaller than the output stage. Its short style makes the GSD collection the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and acceleration accuracy is necessary. The flange result produces highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line stands for 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 series offer the same advantages as the GSB range; the right angle shape makes the GSBL line the perfect match for all powerful applications where space is limited.
