The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing offers been especially designed to reach high torques that beat the competition for products of the same size. All planetary carriers are produced as a cage created from solid material. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water protection relative to protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is definitely tighter tolerances, so all around the gear is a tighter, more exact fit. And the tighter fit means less play in the gear teeth, which is the cause of backlash to begin with. Of 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, an easy way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically carried out by shortening the center distance between gears. As for pre-loading, this can be done using a spring mechanism to hold the gears firmly set up. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount 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 result stage. Its short design makes the GSD series the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it an ideal fit for highly dynamic applications where highest positioning and quickness accuracy is necessary. The flange output produces highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the GSB line; the right angle form makes the GSBL range the perfect match for all powerful applications where space is limited.
