The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides been especially designed to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage made from solid materials. This increases silent operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water safety relative to protection course IP65 in every lines.
One method to reduce backlash is to use precision gears. The concentrate on production in precision gears can be tighter tolerances, so all over the gear will be a tighter, more precise suit. And the tighter suit means less play in the apparatus teeth, which may be the cause of backlash to begin with. Of program, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. As for pre-loading, this could be done using a spring mechanism to carry the gears firmly set up. This also eliminates the perform between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can 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 ideals, the input stage is usually dimensionally smaller than the result stage. Its short design makes the GSD collection the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it an ideal fit for highly powerful applications where highest positioning and velocity 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 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 form makes the GSBL line the perfect match for all powerful applications where space is limited.
