The high-end economy lines GSN & GFE combine high performance 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 provides been especially made to reach high torques that beat the competition for models of the same size. All planetary carriers are produced as a cage created from solid materials. This increases calm operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring 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 is tighter tolerances, so all around the gear will be a tighter, more exact match. And the tighter match means much less play in the apparatus teeth, which may be the cause of backlash in the first place. Of program, precision gears are more expensive, if the application calls for high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. This is typically done by shortening the center 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 your gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a large impact on the quantity of backlash. So for instance, some equipment types such as strain wave gears, or harmonic gear 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 is dimensionally smaller compared to the output stage. Its short style makes the GSD series the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and swiftness accuracy is required. The flange result 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 higher. The GSB line means high performance in mixture 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 line provide 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.
