servo planetary gearbox

The high-end economy lines GSN & GFE combine high performance 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 units of the same size. All planetary carriers are produced as a cage created from solid materials. This increases peaceful operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water security in accordance with protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is certainly tighter tolerances, so all over the gear will be a tighter, more precise suit. And the tighter fit means much less play in the apparatus teeth, which is the cause of backlash to begin with. Of 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 lessen backlash is to make sure one’s teeth mesh tightly together. This is typically done by shortening the center distance between gears. As for pre-loading, this is often done utilizing 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 type of gears used may also have a large impact on the quantity of backlash. So for instance, some gear types such as stress 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 output stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange output creates highest torsional rigidity. For the accommodation 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 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 line 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.
