The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing offers been especially made to reach high torques that defeat the competition for products of the same size. All planetary carriers are produced as a cage made from solid materials. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water security in accordance with protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The focus on production in precision gears can be tighter tolerances, so all over the gear is a tighter, more precise fit. And the tighter match means less play in the gear teeth, which is the trigger of backlash to begin with. Of training course, precision gears are more costly, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically performed by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly set up. This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the kind 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 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 series makes it an ideal fit for highly powerful applications where highest positioning and swiftness accuracy is necessary. The flange result generates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line means high performance in mixture 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 line provide same advantages as the GSB line; the right angle shape makes the GSBL series an ideal match for all dynamic applications where space is bound.
