The high-end economy lines GSN & GFE combine high performance with economic 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 made to reach high torques that beat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water security in accordance with protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears can be tighter tolerances, so all over the gear is a tighter, more exact fit. 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 costly, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a gear design perspective, an easy way to lessen backlash is to ensure the teeth mesh tightly together. This is typically completed by shortening the center distance between gears. For pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity of backlash. So for example, some equipment 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 input stage can be dimensionally smaller compared to the output stage. Its short style makes the GSD line the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and speed accuracy is required. The flange result generates 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 combination 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 series provide same advantages as the GSB series; the right angle form makes the GSBL range the perfect match for all powerful applications where space is limited.
