The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing provides been especially made to reach high torques that defeat the competition for products of the same size. All planetary carriers are produced as a cage created 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 dirt and splash water security relative to protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is tighter tolerances, so all over the gear is a tighter, more specific fit. And the tighter suit 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, but if the application calls for high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. As for pre-loading, this is often done using 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 huge 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. Because of the lower torque ideals, the input stage can be dimensionally smaller than the result stage. Its short design makes the GSD line the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and rate accuracy is required. The flange result produces 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 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 line offer the same advantages as the GSB line; the right angle shape makes the GSBL line an ideal match for all powerful applications where space is bound.
