The high-end economy lines GSN & GFE combine high performance 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 has been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage created from solid material. This increases tranquil operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water security relative to protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all around the gear is a tighter, more exact fit. And the tighter suit means less play in the gear teeth, which may be the cause of backlash in the first place. Of program, precision gears are more costly, but if the application demands high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to ensure the teeth mesh tightly together. That is typically performed by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to hold the gears firmly in place. 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 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 values, the input stage is definitely dimensionally smaller compared to the output stage. Its short design makes the GSD series the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it the perfect fit for highly dynamic applications where highest positioning and swiftness accuracy is required. The flange result generates highest torsional rigidity. For the accommodation of particularly 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 collection provide same advantages as the GSB series; the right angle form makes the GSBL range an ideal match for all dynamic applications where space is bound.
