The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing offers 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 tranquil operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water protection relative to protection course IP65 in every lines.
One method 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 precise fit. And the tighter fit means much less play in the apparatus teeth, which is the cause of backlash in the first place. 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 gear design perspective, an easy way to reduce backlash is to ensure one’s teeth mesh tightly together. That is typically performed by shortening 
the guts distance between gears. For pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the perform between your gear teeth and therefore 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 stress 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. Because of the lower torque ideals, the input stage is definitely dimensionally smaller compared to the result stage. Its short style makes the GSD line the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and quickness accuracy is required. 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 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 line provide same advantages as the GSB series; the right angle shape makes the GSBL range an ideal match for all dynamic applications where space is bound.
