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 made to reach high torques that defeat the competition for models of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water security in accordance with protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is tighter tolerances, so all over the gear will be a tighter, more specific fit. And the tighter suit means less play in the gear teeth, which is the trigger of backlash in the first place. Of course, precision gears are more costly, but if the application calls for high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to make sure one’s teeth mesh tightly together. This is typically completed by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to hold 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 can also have a huge impact on the quantity 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 input stage is definitely dimensionally smaller compared to the output stage. Its short style makes the GSD line the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it an ideal fit for highly powerful applications where 
highest positioning and velocity accuracy is required. The flange result produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination 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 range offer the same advantages as the GSB series; the right angle shape makes the GSBL range the perfect match for all dynamic applications where space is bound.
