The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing provides been especially made to reach high torques that defeat the competition for units of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases silent operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water safety relative to protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is tighter tolerances, so all around the gear is a tighter, more exact match. And the tighter suit means less play in the gear teeth, which may be the cause of backlash in the first place. Of training course, precision gears are more expensive, but if the application demands high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. This is typically completed by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the amount of backlash. So for example, some equipment 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. Due to the lower torque values, the insight stage is certainly dimensionally smaller compared to the result stage. Its short design makes the GSD collection 
the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and swiftness accuracy is required. The flange output creates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line means high performance in combination with low backlash and high precision. Its robust, one-piece housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB collection; the right angle form makes the GSBL line an ideal match for all powerful applications where space is bound.
