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 full needle bearing offers been especially designed to reach high torques that beat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases silent operating characteristics while at precisely the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water safety in accordance with protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is definitely tighter tolerances, therefore all around the gear is a tighter, more precise suit. And the tighter fit means less play in the gear teeth, which may be the cause of backlash to start with. Of program, precision gears are more costly, if the application demands high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. For pre-loading, this is often done using a spring mechanism to hold 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 may also have a large impact on the amount of backlash. So for example, some equipment 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. Because of the lower torque values, the insight stage is usually dimensionally smaller compared to the result stage. Its short style makes the GSD range the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it an ideal fit for highly dynamic applications where highest positioning and speed 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 stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB series; the right angle shape makes the GSBL collection the perfect match for all powerful applications where space is bound.
