The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing offers been especially designed to reach high torques that defeat the competition for products of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water security relative to protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is tighter tolerances, so all around the gear is a tighter, more exact suit. And the tighter suit means much less play in the apparatus teeth, which is the cause of backlash to begin with. Of course, precision gears are more expensive, but if the application demands high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure one’s teeth mesh tightly together. That is typically completed by shortening the center distance between gears. For pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy 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 equipment types such as strain wave gears, or harmonic equipment 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 values, the input stage is certainly dimensionally smaller than the output stage. Its short design makes the GSD collection the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and acceleration accuracy is required. The flange output creates highest torsional rigidity. For the lodging 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 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 provide same advantages as the GSB range; the right angle form makes the GSBL line an ideal match for all powerful applications where space is limited.
