The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing offers been especially made to reach high torques that defeat the competition for products of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring 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 concentrate on production in precision gears is certainly tighter tolerances, so all over the gear will be a tighter, more exact fit. And the tighter match means much less play in the apparatus teeth, which is the cause of backlash in the first place. Of course, precision gears are more expensive, but 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 lessen backlash is to make sure the teeth mesh tightly together. This is typically done by shortening the guts distance between gears. For pre-loading, this could be done using a spring mechanism to hold the gears firmly in place. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a large impact on the amount of backlash. So for instance, 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. Due to the lower torque ideals, the input stage is usually dimensionally smaller compared to the result stage. Its short style makes the GSD series the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and speed accuracy is necessary. The flange result generates 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 higher 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 line; the right angle shape makes the GSBL series the perfect match for all dynamic applications where space is limited.
