The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing has been especially made to reach high torques that beat the competition for products of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases peaceful operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water security in accordance with protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is certainly tighter tolerances, so all around the gear is a tighter, more exact fit. And the tighter fit means much less play in the gear teeth, which is the cause of backlash in the first place. Of training course, precision gears are more costly, if the application demands high accuracy, after that 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. That is typically performed by shortening the guts distance between gears. For pre-loading, this can be done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount 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 certainly dimensionally smaller than the result stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange result generates highest torsional rigidity. For the accommodation 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 series provide same advantages as the GSB line; the right angle form makes the GSBL series the perfect match for all dynamic applications where space is bound.
