The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum 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 made from solid material. This increases quiet 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 in accordance with protection class 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 precise match. And the tighter match means less play in the gear teeth, which is the cause of backlash in the first place. Of training course, precision gears are more costly, 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 make sure the teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. For pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the perform between the 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 example, some equipment types such as stress 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 values, the insight stage can be dimensionally smaller than the result stage. Its short style makes the GSD range the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it the perfect fit for highly dynamic applications where highest positioning and acceleration accuracy is required. The flange output generates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line means 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 line provide same advantages as the GSB line; the right angle shape makes the GSBL line the perfect match for all dynamic applications where space is bound.
