The high-end economy lines GSN & GFE combine powerful 
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 devices of the same size. All planetary carriers are produced as a cage created from solid materials. This increases calm operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water safety in accordance with protection class IP65 in all lines.
One way to reduce backlash is by using precision gears. The concentrate on production in precision gears is usually tighter tolerances, so all over the gear is a tighter, more precise match. And the tighter fit means less play in the gear teeth, which is the cause of backlash to begin with. Of course, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to make sure the teeth mesh tightly together. This is typically completed by shortening the guts distance between gears. For pre-loading, this could be done utilizing 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 type of gears used may also have a huge impact on the quantity of backlash. So for example, 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 series the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange output creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line means high performance in mixture 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 range; the right angle shape makes the GSBL collection an ideal match for all dynamic applications where space is limited.
