The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing provides been especially designed to reach high torques that defeat the competition for devices of the same size. All planetary carriers are produced as a cage created from solid material. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security relative to protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears can be tighter tolerances, therefore all around the gear will be a tighter, more precise suit. And the tighter suit means much less play in the apparatus 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 equipment design perspective, a simple way to reduce backlash is to ensure the teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. For pre-loading, this could be done utilizing a spring mechanism to carry 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 can also have a large impact on the amount 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 insight stage can be dimensionally smaller than the output stage. Its short design makes the GSD line the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and quickness accuracy is necessary. 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 higher. The GSB line means high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for 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 line; the right angle form makes the GSBL line the perfect match for all dynamic applications where space is limited.
This is exactly how worm drive servo can be used for your advantage.
