The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing offers been especially designed to reach high torques that beat the competition for systems of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water security in accordance with protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is usually tighter tolerances, so all over the gear is a tighter, more precise match. And the tighter suit means much less play in the gear teeth, which may be the trigger of backlash in the first place. Of training course, precision gears are more expensive, if the application calls for high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically completed by shortening the guts distance between gears. For pre-loading, this could be done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for example, some gear types such as strain wave gears, or harmonic equipment 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 ideals, the input stage is certainly dimensionally smaller compared to the output stage. Its short style makes the GSD collection the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is required. The flange result creates highest torsional rigidity. For the lodging of especially 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 range provide same advantages as the GSB line; the right angle form makes the GSBL series an ideal match for all dynamic applications where space is limited.
