The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that beat the competition for products of the same size. All planetary carriers are produced as a cage made from solid materials. This increases calm operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water protection relative to protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all around the gear will be a tighter, more exact suit. And the tighter suit means less play in the gear teeth, which is the cause of backlash in the first place. Of course, precision gears are more expensive, 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 lessen backlash is to ensure the teeth mesh tightly together. That is typically done by shortening the guts distance between gears. As for pre-loading, this is often done using a spring mechanism to hold the gears firmly in place. This also eliminates the perform between the gear teeth and therefore 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 definitely dimensionally smaller than the result stage. Its short design makes the GSD line the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and acceleration accuracy is required. The flange result produces highest torsional rigidity. For the accommodation 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 allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB range; the right angle shape makes the GSBL line an ideal match for all powerful applications where space is bound.
