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 full needle bearing offers been especially designed to reach high torques that beat the competition for units of the same size. All planetary carriers are produced as a cage made from solid materials. This increases peaceful operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety relative to protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is usually 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 course, precision gears are more expensive, 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 reduce backlash is to ensure the teeth mesh tightly together. This is typically performed by shortening the center distance between gears. As for pre-loading, this could be done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a huge impact on the amount of backlash. So for instance, some equipment 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 ideals, the input stage is dimensionally smaller than the result stage. Its short design makes the GSD series the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is required. 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 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 collection provide same advantages as the GSB range; the right angle form makes the GSBL series an ideal match for all powerful applications where space is limited.
