The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing offers been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage made from solid material. This increases tranquil operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water security relative to protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is certainly tighter tolerances, so all over the gear will be a tighter, more specific fit. And the tighter fit means less play in the gear teeth, which may be the cause of backlash to begin with. Of program, precision gears are more expensive, if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a simple way to reduce backlash is to ensure one’s teeth mesh tightly together. That is typically done by shortening the guts distance between gears. For pre-loading, this could be done utilizing a spring mechanism to hold 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 can also have a large impact on the quantity of backlash. So for instance, some gear 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 usually dimensionally smaller than the result stage. Its short style makes the GSD collection the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and velocity accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available 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 series offer the same advantages as the GSB range; the right angle form makes the GSBL range an ideal match for all dynamic applications where space is limited.
