The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water protection in accordance with protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on production in precision gears is 
tighter tolerances, so all over the gear is a tighter, more exact match. And the tighter fit means less play in the apparatus teeth, which is 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 could be the way to go.
From a gear design perspective, a simple way to reduce backlash is to make sure the teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. For pre-loading, this could be done using a spring mechanism to hold the gears firmly set up. This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a large impact on the quantity of backlash. So for example, some equipment types such as strain 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 values, the input stage is dimensionally smaller than the output stage. Its short design makes the GSD range the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and acceleration accuracy is required. The flange result produces highest torsional rigidity. For the accommodation 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 combination with low backlash and high precision. Its robust, one-piece housing allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB range; the right angle form makes the GSBL collection an ideal match for all powerful applications where space is limited.
