The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing has 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 peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety in accordance with protection class IP65 in all lines.
One way to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is usually tighter tolerances, so all around the gear is a tighter, more precise suit. And the tighter match means much less play in the gear teeth, which is the trigger of backlash to begin with. Of program, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure the teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. As for pre-loading, this could be done using a spring mechanism to hold the gears firmly set up. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a large impact on the amount of backlash. So for example, some gear 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 result stage. Its short design makes the GSD range the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and swiftness accuracy is necessary. The flange output creates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available 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 permits a higher 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 collection; the right angle form makes the GSBL line the perfect match for all dynamic applications where space is bound.
