The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing offers been especially made to reach high torques that defeat the competition for devices of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water protection in accordance with protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is usually tighter tolerances, so all around the gear will be a tighter, more specific match. And the tighter fit means much less play in the apparatus teeth, which is the trigger of backlash in the first place. Of course, 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, a simple way to reduce backlash is to ensure one’s teeth mesh tightly together. This is typically performed by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between the 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 equipment types such as strain wave gears, or harmonic gear 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 values, the input stage is definitely dimensionally smaller than the output stage. Its short design makes the GSD line the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD collection makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is required. The flange output creates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in mixture 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 collection; the right angle shape makes the GSBL line an ideal match for all dynamic applications where space is bound.
