The high-end economy lines GSN & GFE combine powerful 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 offers been especially designed 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 materials. This increases quiet operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water safety relative to protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The concentrate on production in precision gears is tighter tolerances, so all over the gear is a tighter, more precise suit. And the tighter suit means less play in the gear teeth, which may be the cause of backlash to begin with. Of program, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically performed by shortening the center distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly in place. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the amount of backlash. So for example, some equipment 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. Because of the lower torque values, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is required. The flange result produces highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. 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 provide same advantages as the GSB collection; the right angle form makes the GSBL collection an ideal match for all dynamic applications where 
space is bound.
