The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing offers been especially designed to reach high torques that beat the competition for systems of the same size. All planetary carriers are produced as a cage created from solid materials. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water security in accordance with protection class IP65 in all lines.
One method to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears can be tighter tolerances, so all over the gear is a tighter, more specific fit. And the tighter match 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, if the application demands high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to make sure the teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. For pre-loading, this could be done using a spring mechanism to hold the gears firmly set up. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the quantity of backlash. So for example, some gear types such as stress wave gears, or harmonic equipment 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 compared to the result stage. Its short style makes the GSD range the ideal 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 speed accuracy is required. The flange output generates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available 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 series provide same advantages as the GSB collection; the right angle shape makes the GSBL collection an ideal match for all powerful applications where space is bound.
