The high-end economy lines GSN & GFE combine powerful 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 has been especially made to reach high torques that defeat the competition for units of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases noiseless 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 course IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on production in precision gears is tighter tolerances, so all around the gear is a tighter, more precise match. And the tighter match means less play in the apparatus teeth, which is 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 ensure one’s teeth mesh tightly together. This is typically done by shortening the center distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the perform between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a large impact on the amount of backlash. So for example, some gear types such as zero backlash planetary gearbox 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 output stage. Its short style makes the GSD collection the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange output produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available 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 series offer the same advantages as the GSB collection; the right angle form makes the GSBL series an ideal match for all dynamic applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-stage motors used with a single-stage AC power supply and three-phase motors used in combination with a three-phase AC power. A single-phase motor can be operated by simply linking it to a single-phase power via the supplied capacitor. A three-phase motor will not require a capacitor. All you have to is for connecting the motor directly to a three-phase AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly suitable applications for the new range are those which place the best demands on positioning precision, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest production requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
