The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage made from solid material. This increases quiet 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 course IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is certainly tighter tolerances, so all over the gear is a tighter, more exact 
suit. And the tighter fit means less play in the apparatus teeth, which may be the cause of backlash in the first place. Of program, precision gears are more expensive, but if the application demands high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to ensure one’s teeth mesh tightly together. That is typically performed by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly set up. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a large impact on the amount of backlash. So for example, some gear types such as stress wave gears, or harmonic equipment 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 input stage is dimensionally smaller than the result stage. Its short design makes the GSD collection the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and quickness accuracy is required. The flange result produces highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line means high performance in combination 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 series provide same advantages as the GSB range; the right angle form makes the GSBL line the perfect match for all powerful applications where space is bound.
