The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing offers been especially made to reach high torques that beat 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 precision and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water security 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 is definitely tighter tolerances, so all around the gear will be a tighter, more specific match. And the tighter suit means much less play in the apparatus teeth, which may be the cause of backlash to begin with. Of training course, precision gears are more expensive, but if the application demands high accuracy, then precision gearing may 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. That is typically completed by shortening the guts distance between gears. For pre-loading, this could be done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the play between the gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the amount of backlash. So for instance, some gear types such as stress wave gears, or harmonic gear 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 ideals, the input stage is definitely dimensionally smaller compared to the output stage. Its short style makes the GSD range the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and rate accuracy is required. The flange output creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line stands for 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 collection offer the same advantages as the GSB collection; the right angle form makes the GSBL series an ideal match for all powerful applications where space is bound.
