The high-end economy lines GSN & GFE combine high performance 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 made to reach high torques that defeat the competition for products of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water safety relative to protection course IP65 in every lines.
One method to reduce backlash is 
to use precision gears. The concentrate on production in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more precise match. And the tighter suit means less play in the gear teeth, which is the trigger of backlash to begin with. Of program, precision gears are more costly, but if the application calls for high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, a simple way to reduce 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 can be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a huge 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 certainly dimensionally smaller than the result stage. Its short style makes the GSD line the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and swiftness accuracy is required. The flange result creates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available 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 permits a higher 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 line; the right angle form makes the GSBL range an ideal match for all powerful applications where space is bound.
