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 has been especially designed to reach high torques that defeat the competition for units of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety 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 certainly tighter tolerances, so all around the gear will be a tighter, more specific match. And the tighter match means much less play in the gear teeth, which may be the trigger of backlash in the first place. Of program, precision gears are more costly, but 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 reduce backlash is to ensure the teeth mesh tightly together. This is typically performed by shortening the center distance between gears. For pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly in place. 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. Due to the lower torque values, the input stage is dimensionally smaller compared to the result stage. Its short style makes the GSD series the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and acceleration accuracy is necessary. The flange result 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 stands for 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 series provide same advantages as the GSB line; the right angle shape makes the GSBL range the perfect match for all dynamic applications where space is limited.
