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 has been especially made to reach high torques that defeat the competition for products of the same size. All planetary carriers are manufactured 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 ring ensures maximum dirt and splash water safety in accordance with protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is usually tighter tolerances, so all over the gear is a tighter, more specific match. And the tighter fit means less play in the gear teeth, which may be the trigger of backlash to begin with. Of program, precision gears are more costly, but if the application demands high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. This is typically done by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a large impact on the quantity of backlash. So for example, some gear types such as strain 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. Due to the lower torque values, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD line the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and speed accuracy is required. The flange result creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line means high performance in combination 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 range offer the same advantages as the GSB collection; the right angle shape makes the GSBL range the perfect match for all powerful applications where space is limited.
