The high-end economy lines GSN & GFE combine powerful 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 beat the competition for devices of the same size. All planetary carriers 
are produced as a cage made from solid materials. This increases silent operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water safety relative to protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all around the gear will be a tighter, more exact fit. And the tighter match means less play in the gear teeth, which may be the cause of backlash to begin with. Of program, precision gears are more costly, if the application calls for 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 make sure one’s teeth mesh tightly together. This is typically performed by shortening the center distance between gears. For pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the play between the gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for example, some equipment types such as strain wave gears, or harmonic equipment 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 definitely 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 line makes it an ideal fit for highly dynamic applications where highest positioning and speed accuracy is required. The flange output creates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. 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 series; the right angle form makes the GSBL series an ideal match for all dynamic applications where space is bound.
