The high-end economy lines GSN & GFE combine powerful with economic 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 defeat the competition for devices of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water security relative to protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears is definitely tighter tolerances, so all over the gear is a tighter, more specific suit. And the tighter fit means much less play in the gear teeth, which is the trigger of backlash to begin with. Of course, precision gears are more costly, if the application calls for high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to make sure the teeth mesh tightly 
together. This is typically performed by shortening the center distance between gears. For pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount of backlash. So for instance, some gear 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. Because of the lower torque values, the input stage is definitely dimensionally smaller than the output stage. Its short style makes the GSD range the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it an ideal fit for highly dynamic applications where highest positioning and swiftness accuracy is necessary. The flange output generates 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 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 range offer the same advantages as the GSB line; the right angle form makes the GSBL collection the perfect match for all powerful applications where space is limited.
zero backlash planetary gearbox is utilized to fit in any daily regimen.
