The high-end economy lines GSN & GFE combine high performance 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 designed 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 quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water safety relative to protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The focus on production in precision gears can be tighter tolerances, so all over the gear is a tighter, more exact fit. And the tighter match means much less play in the gear teeth, which may be the cause of backlash to start 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 lessen 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 play 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 equipment types such as stress wave gears, or harmonic equipment drives, have 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 insight stage is usually dimensionally smaller compared to the output stage. Its short style makes the GSD series the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and quickness accuracy is required. The flange output produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective 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 higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB collection; the right angle form makes the GSBL line the perfect match for all powerful applications where space is limited.
