The high-end economy lines GSN & GFE combine high performance with economic 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 models of the same size. All planetary carriers are produced as a cage made from solid materials. This increases noiseless operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety relative to protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is 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 is the cause of backlash to begin with. Of program, precision gears are more costly, if the application demands high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, an easy way to reduce backlash is to ensure one’s teeth mesh tightly together. This is typically completed by shortening the center distance between gears. For pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the perform between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity of backlash. So for instance, some gear 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. Due to the lower torque values, the input stage is certainly dimensionally smaller compared to the output stage. Its short style makes the GSD line the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it the perfect fit for highly dynamic 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 higher. The GSB line stands for 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 range; the right angle form makes the GSBL line an ideal match for all dynamic applications where space is bound.
