The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum 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 the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water security in accordance with protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is definitely tighter tolerances, so all over the gear is a tighter, more precise suit. And the tighter fit means less play in the gear teeth, which is the trigger of backlash to begin with. Of course, precision gears are more expensive, but if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a simple way to reduce backlash is to make sure one’s teeth mesh tightly together. This is typically performed 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 enjoy between the gear teeth and therefore 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 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. Because of the lower torque values, the input stage is definitely dimensionally smaller compared to the output stage. Its short style makes the GSD series the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and velocity accuracy is necessary. The flange output creates highest torsional rigidity. For the lodging of especially 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 allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series offer the same advantages as the GSB series; the right angle form makes the GSBL line the perfect match for all powerful applications where space is bound.
