The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built 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 units of the same size. All planetary carriers are produced as a cage created from solid materials. This increases calm operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water protection in accordance with protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is definitely tighter tolerances, so all around the gear is a tighter, more precise suit. And the tighter match means less play in the gear teeth, which may be the cause of backlash in the first place. Of program, precision gears are more costly, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to make sure the teeth mesh tightly together. This is typically done by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to hold the gears firmly set up. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity of backlash. So for instance, some equipment 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 is definitely dimensionally smaller than the output stage. Its short design makes the GSD line 
the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and speed 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection provide same advantages as the GSB series; the right angle form makes the GSBL series the perfect match for all dynamic applications where space is bound.
