The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides been especially made 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 material. This increases tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water protection in accordance with protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears can be tighter tolerances, so all around the gear is a tighter, more precise fit. And the tighter fit means much less play in the apparatus teeth, which is the cause of backlash to begin with. Of course, precision gears are more expensive, if the application demands high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a large impact on the quantity of backlash. So for instance, some equipment 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. Because of the lower torque ideals, the input stage is dimensionally smaller than the result stage. Its short style makes the GSD range the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and quickness accuracy is necessary. The flange result produces 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 high 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 range; the right angle form makes the GSBL line the perfect match for all dynamic applications where space is bound.
