The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially made to reach high torques that defeat the competition for units of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security in accordance with protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is certainly tighter tolerances, so all over the gear will be a tighter, more precise suit. 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, after that precision gearing may be the way to go.
From a gear design perspective, a simple way to reduce backlash is to ensure the teeth mesh tightly together. That is typically performed by shortening the guts 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 enjoy 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 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 values, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD series the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and quickness accuracy is required. The flange output 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 combination with low backlash and high precision. Its robust, one-piece housing allows for a high 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 shape makes the GSBL range an ideal match for all powerful applications where space is bound.
