The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially designed to reach high torques that beat the competition for products of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water safety in accordance with protection class IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears can be tighter tolerances, so all over the gear is a tighter, more precise match. And the tighter match means much less play in the apparatus teeth, which may be the trigger of backlash in the first place. Of program, 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, a simple way to reduce backlash is to make sure one’s teeth mesh tightly together. This is typically performed by shortening the center distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for instance, some gear types such as stress 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. Due to the lower torque ideals, the input stage is usually dimensionally smaller than the result stage. Its short style makes the GSD collection the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and speed accuracy is required. The flange output produces highest torsional rigidity. For the accommodation of especially 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 permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB line; the right angle form makes the GSBL series an ideal match for all dynamic applications where space is limited.

No various other company has been able to contend with our new zero backlash planetary gearbox.
