The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially designed to reach high torques that defeat the competition for products of the same size. All planetary carriers are manufactured as a cage created from solid materials. 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 security in accordance with protection class IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on production in precision gears is tighter tolerances, therefore all over the gear is a tighter, more precise fit. 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, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. This is typically completed by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to hold the gears firmly in place. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the amount of backlash. So for instance, some gear types such as strain wave gears, or harmonic gear drives, possess 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 insight stage is definitely dimensionally smaller compared to the output stage. Its short style makes the GSD range the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and swiftness accuracy is necessary. The flange output produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line means 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 provide same advantages as the GSB range; the right angle form makes the GSBL range an ideal match for all dynamic applications where space is limited.
