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 provides been especially made to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases silent operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water security 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 can be tighter tolerances, so all over the gear will be a tighter, more specific match. And the tighter suit means less play in the gear teeth, which may be the cause of backlash in the first place. Of training course, precision gears are more expensive, if the application calls for high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically performed by shortening the center distance between gears. As for pre-loading, this can be done using a spring mechanism to carry the gears firmly set up. This also eliminates the play between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may 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, 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 compared to the result stage. Its short design makes the GSD series the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and swiftness accuracy is required. The flange output creates highest torsional rigidity. For the lodging of especially 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 allows for a higher 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 series an ideal match for all powerful applications where space is limited.
