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 full needle bearing offers been especially made to reach high torques that beat the competition for products of the same size. All planetary carriers are produced as a cage created from solid materials. This increases silent operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water protection in accordance with protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is usually tighter tolerances, so all over the gear will be a tighter, more precise suit. And the tighter match means less play in the apparatus 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 equipment design perspective, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount of backlash. So for example, some equipment 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. Because of the lower torque ideals, the input stage is certainly dimensionally smaller compared to the result stage. Its short design makes the GSD series the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and acceleration accuracy is necessary. The flange result creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line means 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 series provide same advantages as the GSB range; the right angle form makes the GSBL line the perfect match for all dynamic applications where space is bound.
