The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases peaceful operating characteristics while at exactly the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water protection in accordance with protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is definitely tighter tolerances, so all around the gear is a tighter, more precise fit. And the tighter fit means less play in the apparatus teeth, which may be the trigger of backlash to begin with. Of training 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 one’s teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity of backlash. So for instance, some equipment types such as stress wave gears, or harmonic gear 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 insight stage is dimensionally smaller than the output stage. Its short design makes the GSD collection the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and velocity accuracy is required. The flange output generates highest torsional rigidity. For the accommodation 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 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 line offer the same advantages as the GSB range; the right angle shape makes the GSBL line the perfect match for all powerful applications where space is bound.
