The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially designed to reach high torques that beat the competition for units of the same size. All planetary carriers are produced as a cage made from solid materials. This increases tranquil operating characteristics while at specifically the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water safety relative to protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all over the gear will be a tighter, more precise fit. And the tighter suit means less play in the apparatus teeth, which may be the cause of backlash in the first place. Of course, precision gears are more costly, but if the application demands high accuracy, then precision gearing may be the way to go.
From a gear design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. That is typically completed by shortening the guts distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may 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, 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 insight stage is usually dimensionally smaller compared to the output stage. Its short design makes the GSD range the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange output generates highest torsional rigidity. For the lodging of particularly 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 permits a higher 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 collection; the right angle form makes the GSBL series an ideal match for all dynamic applications where space is bound.
