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 provides been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage created from solid material. This increases calm operating characteristics while at specifically the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water safety relative to protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all around the gear will be a tighter, more specific match. And the tighter fit means less play in the apparatus teeth, which is the trigger of backlash to begin with. Of course, precision gears are more costly, if the application calls for high accuracy, then precision gearing may be the way to go.
From a gear design perspective, a simple way to reduce backlash is to ensure one’s teeth mesh tightly together. This is typically done by shortening the guts distance between gears. For pre-loading, this could be done utilizing 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 type of gears used can 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 can be dimensionally smaller compared to the result stage. Its short design 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 velocity accuracy is required. The flange output produces 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 means high performance in combination with low backlash and high precision. Its robust, one-piece housing allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection provide same advantages as the GSB line; the right angle shape makes the GSBL line the perfect match for all powerful applications where space is bound.
