The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing offers been especially designed to reach high torques that defeat the competition for units of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dirt 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 manufacturing in precision gears is definitely tighter tolerances, therefore all over the gear will be a tighter, more precise match. And the tighter match means much less play in the gear teeth, which is the trigger of backlash to begin with. Of program, precision gears are more expensive, but if the application demands high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to ensure one’s teeth mesh tightly together. This is typically completed by shortening the guts distance between gears. For pre-loading, this could be done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity of backlash. So for example, some gear types such as strain 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 ideals, the input stage is definitely dimensionally smaller than the output stage. Its short style makes the GSD series the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and rate accuracy is required. The flange output produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line means high performance in combination with low backlash and high precision. Its robust, one-piece housing permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series offer the same advantages as the GSB collection; the right angle shape makes the GSBL line an ideal match for all powerful applications where space is bound.
