The high-end economy lines GSN & 
GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing provides been especially designed to reach high torques that beat the competition for products of the same size. All planetary carriers are produced as a cage created from solid materials. This increases peaceful operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water protection in accordance with protection class IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is usually tighter tolerances, so all over the gear is a tighter, more exact match. And the tighter suit means much less play in the apparatus teeth, which is the trigger of backlash to begin with. Of course, precision gears are more expensive, 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 one’s teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity of backlash. So for example, some gear types such as stress 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 values, the insight stage is usually dimensionally smaller compared to the output stage. Its short style makes the GSD series the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and quickness accuracy is necessary. The flange output produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available 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 high 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 powerful applications where space is bound.
