The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides 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 created from solid materials. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water safety in accordance with protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is usually tighter tolerances, so all around the gear is a tighter, more exact match. And the tighter match means much less play in the gear teeth, which may be the trigger of backlash to begin with. Of program, precision gears are more costly, if the application calls for 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 make sure one’s teeth mesh tightly together. That is typically done by shortening the guts distance between gears. As for pre-loading, this could be done using a spring mechanism to carry the gears firmly set up. This also eliminates the perform between your 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 instance, some gear 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. Due to the lower torque values, the input stage is usually dimensionally smaller compared to the result stage. Its short style makes the GSD series the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and rate accuracy is necessary. The flange result creates 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 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 series; the right angle shape makes the GSBL series an ideal match for all powerful applications where space is limited.
