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 offers been especially designed to reach high torques that defeat the competition for products of the same size. All planetary carriers are produced as a cage created from solid material. This increases peaceful operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water safety relative to protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all around the gear is a tighter, more precise suit. And the tighter fit means much less play in the gear teeth, which may be the trigger of backlash in the first place. Of course, precision gears are more costly, but if the application demands high accuracy, then precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to ensure the teeth mesh tightly together. This 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 perform between your 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 example, some equipment types such as stress 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. Due to the lower torque values, the insight stage is dimensionally smaller compared to the output stage. Its short style makes the GSD series the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it the perfect fit for highly dynamic 
applications where highest positioning and rate accuracy is required. The flange output generates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective 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 provide same advantages as the GSB collection; the right angle form makes the GSBL line the perfect match for all powerful applications where space is bound.
