The high-end economy lines GSN & GFE combine powerful 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 provides been especially made to reach high torques that defeat the competition for units of the same size. All planetary carriers are produced as a cage made from solid material. This increases tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water protection relative to protection course IP65 in every lines.
One method to reduce backlash is to use precision gears. The focus on production in precision gears is tighter tolerances, so all around the gear will be a tighter, more exact suit. And the tighter fit means much less play in the apparatus teeth, which may be the cause of backlash in the first place. Of program, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing could 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 completed by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly set up. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the type 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, 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 input stage can be dimensionally smaller than the output stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it the perfect fit for highly dynamic applications where highest positioning and quickness accuracy is necessary. The flange output generates highest torsional rigidity. For the lodging of particularly high 
axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line means high performance in mixture 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 offer the same advantages as the GSB collection; the right angle shape makes the GSBL series the perfect match for all powerful applications where space is bound.
