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 has 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 tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water protection in accordance with protection class IP65 in all 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 will be a tighter, more exact match. And the tighter fit means much less play in the apparatus teeth, which may be the cause of backlash to begin with. Of training course, precision gears are more expensive, but if the application demands high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically carried out by shortening the center 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 the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount of backlash. So for example, some gear 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 input stage is usually dimensionally smaller compared to 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 series makes it the perfect fit for highly dynamic applications where highest positioning and speed accuracy is required. The flange result creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective 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 permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB series; the right angle form makes the GSBL line the perfect match for all powerful applications where space is limited.
