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 has been especially made to reach high torques that defeat the competition for units of the same size. All planetary carriers are produced as a cage made 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 protection relative to protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is usually tighter tolerances, therefore all around the gear is a tighter, more precise suit. And the tighter match means much less play in the gear teeth, which may be the trigger of backlash in the first place. Of program, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a large 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. Because of the lower torque ideals, the insight stage is certainly dimensionally smaller than the output stage. Its short style makes the GSD series 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 rate 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 allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB collection; the right angle form makes the GSBL collection an ideal match for all powerful applications where space is bound.
