The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that defeat the competition for systems of the same size. All planetary carriers are produced as a cage created from solid material. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water security in accordance with protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears can be tighter tolerances, so all around the gear is a tighter, more precise fit. And the tighter fit means less play in the apparatus teeth, which may be the cause of backlash in the first place. Of program, precision gears are more costly, but if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, an easy way to lessen backlash is to make sure one’s teeth mesh tightly together. That is typically performed by shortening the guts distance between gears. For pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the amount of backlash. So for example, some gear 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 ideals, the input stage is certainly dimensionally smaller compared to the result stage. Its short style makes the GSD range the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and acceleration accuracy is necessary. The flange output generates 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 stands for high performance in combination 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 range; the right angle form makes the GSBL collection an ideal match for all powerful applications where space is limited.
