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 entire needle bearing provides been especially made to reach high torques that beat the competition for devices of the same size. All planetary carriers are produced as a cage made from solid materials. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water protection relative to protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all over the gear will be a tighter, more specific match. And the tighter fit means much less play in the gear teeth, which is the trigger of backlash in the first place. Of course, precision gears are more costly, 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 make sure one’s teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. As for pre-loading, this could be done using a spring mechanism to hold the gears firmly in place. This also eliminates the play between your 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 example, some gear types such as stress wave gears, or harmonic gear drives, possess 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 can be dimensionally smaller than the result stage. Its short style makes the GSD collection the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and velocity 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 more. 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 line; the right angle shape makes the GSBL collection an ideal match for all dynamic applications where space 
is bound.
