The high-end economy lines GSN & GFE combine high performance with financial 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 systems of the same size. All planetary carriers are produced as a cage made from solid materials. This increases quiet operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water protection relative to protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is tighter tolerances, so all around the gear will be a tighter, more precise suit. And the tighter suit means much less play in the apparatus teeth, which may be the cause of backlash to begin with. Of training course, precision gears are more expensive, if the application demands high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to ensure the teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. As for pre-loading, this could be done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a large impact on the amount of backlash. So for example, some gear types such as stress 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 values, the input stage can be dimensionally smaller than the output stage. Its short design makes the GSD collection the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange output produces 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 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 series provide same advantages as the GSB line; the right angle form makes the GSBL line an ideal match for all dynamic applications where space is bound.
