The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing offers been especially designed to reach high torques that beat the competition for units of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases tranquil operating characteristics while at 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 class IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is tighter tolerances, so all around the gear will be a tighter, more precise match. And the tighter match means much less play in the gear teeth, which is the trigger of backlash in the first place. Of training course, precision gears are more costly, but if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, an easy way to reduce backlash is to make sure the teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. As for pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the play between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount of backlash. So for example, some equipment types such as strain wave gears, or harmonic equipment drives, possess 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 input stage is usually dimensionally smaller than the output stage. Its short design makes the GSD series the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and rate accuracy is necessary. 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 more. The GSB line stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits 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 collection an ideal match for all dynamic applications where space is limited.
