The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing provides been especially made to reach high torques that beat the competition for models of the same size. All planetary carriers are produced as a cage created from solid materials. This increases peaceful operating characteristics while at specifically the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water security relative to protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, therefore all over the gear will be a tighter, more exact match. And the tighter suit means much less play in the gear teeth, which is the cause of backlash to start with. Of training course, precision gears are more costly, but if the application demands high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to make sure the teeth mesh tightly together. This is typically done by shortening the center distance between gears. For pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly set up. 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 example, some gear types such as strain 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 ideals, the input stage can be dimensionally smaller compared to the result stage. Its short style makes the GSD line the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it the perfect fit for highly dynamic applications where highest positioning and acceleration accuracy is necessary. The flange output produces 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 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 offer the same advantages as the GSB line; the right angle shape makes the GSBL series the perfect match for all dynamic applications where space is limited.
