The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing has 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 made from solid material. This increases noiseless operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water security in accordance with protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears is definitely tighter tolerances, so all over the gear is a tighter, more precise fit. And the tighter match means much less play in the gear teeth, which is the cause of backlash to begin with. Of program, precision gears are more expensive, if the application calls for high accuracy, then precision gearing could be the way to go.
From a gear design perspective, an easy way to lessen backlash is to make sure one’s teeth mesh tightly together. That is typically completed by shortening the center 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 play between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the quantity of backlash. So for instance, some equipment types such as strain wave gears, or harmonic equipment 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 input stage is definitely dimensionally smaller compared to the output stage. Its short style makes the GSD series the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and acceleration accuracy is necessary. The flange output generates 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 permits a higher 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 shape makes the GSBL range an ideal match for all powerful applications where space is bound.
