The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and 
smooth running. The full needle bearing provides been especially designed to reach high torques that beat the competition for units of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water security in accordance with protection course IP65 in every lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all over the gear will be a tighter, more precise fit. 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 demands high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, an easy way to reduce backlash is to make sure the teeth mesh tightly together. This is typically completed by shortening the guts distance between gears. For pre-loading, this is often done using a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity of backlash. So for instance, 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. Due to the lower torque ideals, the input stage is usually dimensionally smaller than the result stage. Its short design makes the GSD range the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and rate accuracy is necessary. The flange result creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. 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 collection offer the same advantages as the GSB collection; the right angle shape makes the GSBL series the perfect match for all dynamic applications where space is bound.
