The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially designed to reach high torques that beat the competition for units of the same size. All planetary carriers are produced as a cage made from solid materials. This increases tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water security relative to protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is usually tighter tolerances, so all over the gear is a tighter, more precise match. And the tighter fit means much less play in the gear teeth, which may be the trigger of backlash in the first place. Of training course, precision gears are more expensive, but if the application calls for high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen 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 could be done using a spring mechanism to hold the gears firmly set up. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the amount of backlash. So for example, 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. Because of the lower torque ideals, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD line the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and quickness accuracy is necessary. The flange output creates 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 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 line offer the same advantages as the GSB series; the right angle shape makes the GSBL range an ideal match for all powerful applications where space is bound.
