The high-end economy lines GSN 
& GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing has been especially made to reach high torques that beat the competition for devices of the same size. All planetary carriers are produced as a cage made from solid materials. 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 security relative to protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more precise match. And the tighter match means much less play in the gear teeth, which is the trigger of backlash in the first place. Of program, precision gears are more expensive, but if the application demands 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 ensure one’s teeth mesh tightly together. This is typically completed by shortening the guts distance between gears. For pre-loading, this could be done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between the 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 example, some gear 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 ideals, the input stage is dimensionally smaller compared to the output stage. Its short design makes the GSD range the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange output generates highest torsional rigidity. For the lodging 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 permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB collection; the right angle shape makes the GSBL collection the perfect match for all powerful applications where space is bound.
