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 full needle bearing has been especially designed to reach high torques that defeat the competition for systems of the same size. All planetary carriers are produced as a cage made from solid material. This increases quiet operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water protection in accordance with protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, therefore all around 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 cause of backlash to start with. Of program, 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, a simple way to lessen backlash is to make sure one’s teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. As for pre-loading, this could be done using a spring mechanism to hold the gears firmly in place. This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a large 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 ideals, the input stage is usually dimensionally smaller than the output stage. Its short style makes the GSD collection the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. The flange output creates highest torsional rigidity. For the accommodation 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 allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line offer the same advantages as the GSB line; the right angle shape makes the GSBL range the perfect match for all dynamic applications where space is limited.
