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 has been especially made to reach high torques that beat the competition for systems of the same size. All planetary carriers are produced as a cage made from solid material. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water security relative to protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is certainly tighter tolerances, so all over the gear is a tighter, more specific match. And the tighter match means much less play in the gear teeth, which is the cause of backlash to begin with. Of training course, precision gears are more costly, 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 done by shortening the guts distance between gears. For pre-loading, this could be done using a spring mechanism to hold the gears firmly set up. This also eliminates the play between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for instance, 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. Due to the lower torque values, the input stage can be dimensionally smaller compared to the output stage. Its short design makes the GSD series the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and quickness accuracy is necessary. The flange result generates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available 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 series offer the same advantages as the GSB series; the right angle shape makes the GSBL collection an ideal match for all powerful applications where space is limited.
