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 has 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 created from solid material. This increases silent 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 relative to protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more exact fit. And the tighter match 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 demands high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, a simple way to reduce backlash is to ensure the teeth mesh tightly together. That is typically performed by shortening the center distance between gears. As for pre-loading, this can be done utilizing 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 can also have a large impact on the quantity of backlash. So for instance, some equipment types such as stress 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 can be dimensionally smaller compared to the output stage. Its short style makes the GSD line the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange result generates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination with low backlash and high precision. Its robust, one-piece housing allows for 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 collection an ideal match for all powerful applications where space is limited.
