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 designed to reach high torques that beat the competition for systems of the same size. All planetary carriers are produced as a cage created from solid material. This increases noiseless operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water safety relative to protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears is certainly tighter tolerances, so all around the gear is a tighter, more precise suit. And the tighter match means less play in the apparatus teeth, which may be the cause of backlash in the first place. Of course, precision gears are more costly, if the application calls for high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. That is typically carried out by shortening the center 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 therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for example, some equipment types such as stress wave gears, or harmonic gear 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 insight stage is dimensionally smaller than the result stage. Its short style makes the GSD collection the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and velocity accuracy is necessary. 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 higher. 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 range provide same advantages as the GSB line; the right angle form makes the GSBL range an ideal match for all powerful applications where space is limited.
