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 has 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 materials. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water safety in accordance with protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The concentrate on production in precision gears is certainly tighter tolerances, so all over the gear will be a tighter, more exact match. And the tighter match means much less play in the apparatus teeth, which is the cause of backlash to begin with. Of course, precision gears are more expensive, but if the application calls for high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, an easy way to lessen 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 utilizing 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 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 ideals, the input stage can be dimensionally smaller than 
the output stage. Its short style makes the GSD collection the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and speed accuracy is necessary. The flange result creates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for 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 collection; the right angle form makes the GSBL range an ideal match for all powerful applications where space is bound.
This is how servo planetary gearbox could be utilised for your advantage.
