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 entire needle bearing offers been especially designed to reach high torques that beat the competition for systems of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water safety in accordance with protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is tighter tolerances, so all around the gear is a tighter, more exact fit. And the tighter fit means less play in the apparatus teeth, which is the trigger of backlash in the first place. Of training course, precision gears are more costly, but 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. This is typically completed by shortening the center distance between gears. For pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a huge impact on the quantity of backlash. So for instance, 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 output stage. Its short style makes the GSD line the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it an ideal fit for highly powerful applications where highest positioning and velocity accuracy is necessary. The flange output produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available 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 higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the GSB collection; the right angle form makes the GSBL collection an ideal match for all powerful applications where space is limited.
