The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing provides been especially made to reach high torques that beat the competition for devices of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases noiseless operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water protection relative to protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears can be tighter tolerances, so all around the gear will be a tighter, more specific suit. And the tighter fit means much less play in the apparatus teeth, which is the cause 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, an easy way to reduce backlash is to ensure one’s teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. For pre-loading, this can be done using a spring mechanism to hold the gears firmly in place. 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 amount of backlash. So for instance, some equipment 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. Due to the lower torque ideals, the input stage can be dimensionally smaller compared to the result stage. Its short design 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 acceleration accuracy is required. The flange output produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. 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 range offer the same advantages as the GSB range; the right angle form makes the GSBL line an ideal match for all dynamic applications where space is bound.
