The high-end economy lines GSN & GFE combine powerful 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 provides been especially designed to reach high torques that beat the competition for products of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases silent operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band 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 focus on production in precision gears can be tighter tolerances, so all over the gear will be a tighter, more precise fit. And the tighter fit means less play in the apparatus teeth, which may be 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 may be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. This is typically completed by shortening the center distance between gears. As for pre-loading, this is often done using a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity 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. Due to the lower torque values, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and quickness accuracy is required. The flange output generates highest torsional rigidity. For the accommodation of particularly 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 allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB collection; the right angle shape makes the GSBL range the perfect match for all powerful 
applications where space is bound.
