The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing has been especially designed to reach high torques that defeat the competition for units of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases silent operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water protection in accordance with protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is usually tighter tolerances, so all over the gear is a tighter, more exact suit. And the tighter suit means less play in the apparatus teeth, which is the trigger of backlash in the first place. Of program, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing may 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. That is typically carried out by shortening the center distance between gears. For pre-loading, this could be done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the quantity of backlash. So for example, some gear types such as strain wave gears, or harmonic gear drives, possess zero backlash.

The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Because of the lower torque values, the input stage is certainly dimensionally smaller compared to the result stage. Its short design makes the GSD series 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 required. The flange result creates highest torsional rigidity. For the accommodation 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 range; the right angle form makes the GSBL line an ideal match for all dynamic applications where space is limited.
