The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that defeat the competition for devices of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases peaceful operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water protection in accordance with protection class IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears can be tighter tolerances, therefore all around the gear is a tighter, more specific match. And the tighter fit means much less play in the gear teeth, which is the trigger of backlash to begin with. Of training course, precision gears are more expensive, if the application calls for high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically done by shortening the center distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a huge impact on the amount of backlash. So for instance, some equipment types such as strain wave gears, or harmonic equipment drives, have 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 certainly dimensionally smaller than the result stage. Its short style makes the GSD line the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it the perfect fit for highly powerful applications where highest positioning and quickness accuracy is required. The flange output creates highest torsional rigidity. For the accommodation 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 combination with low backlash and high precision. Its robust, one-piece housing allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection 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 limited.
