The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full worm drive servo china needle bearing provides been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage made from solid material. This increases silent operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water protection in accordance with protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is tighter tolerances, so all over the gear is a tighter, more exact fit. And the tighter fit means less play in the apparatus teeth, which is the trigger of backlash to begin with. Of course, precision gears are more expensive, if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a simple way to reduce backlash is to ensure one’s teeth mesh tightly together. This is typically done by shortening the guts distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the play between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the quantity of backlash. So for instance, some equipment types such as strain wave gears, or harmonic equipment drives, have zero backlash.

The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Because of the lower torque ideals, the input stage is dimensionally smaller than the result stage. Its short style makes the GSD series the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it the perfect fit for highly dynamic applications where highest positioning and quickness accuracy is required. The flange result generates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB line; the right angle shape makes the GSBL collection the perfect match for all powerful applications where space is limited.

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