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 entire needle bearing offers been especially made to reach high torques that beat the competition for units of the same size. All planetary carriers are produced as a cage created from solid material. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft 
sealing ring ensures maximum dirt and splash water safety relative to protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all around the gear will be a tighter, more exact match. And the tighter fit means less play in the gear teeth, which is the cause of backlash to begin with. Of course, precision gears are more costly, 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 one’s teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a large impact on the quantity 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 ideals, the input stage can be dimensionally smaller than the result stage. Its short style makes the GSD range the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and speed accuracy is required. The flange result creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available 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 allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB range; the right angle shape makes the GSBL series the perfect match for all dynamic applications where space is limited.
