The high-end economy lines GSN & GFE combine powerful with financial 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 defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases tranquil operating characteristics while at exactly the same time improving positioning precision and worm drive servo reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety in accordance with protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears can be tighter tolerances, so all around the gear will be a tighter, more specific suit. And the tighter suit means much less play in the gear teeth, which may be the trigger of backlash to begin with. Of training course, precision gears are more expensive, but if the application demands high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to ensure one’s teeth mesh tightly together. That is typically completed by shortening the guts distance between gears. For pre-loading, this can be done using 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 kind of gears used may also have a huge impact on the amount 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. Because of the lower torque values, the input stage can be dimensionally smaller than the result stage. Its short design makes the GSD range the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD range 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 elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination 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 range offer the same advantages as the GSB line; the right angle form makes the GSBL series the perfect match for all dynamic applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-phase motors used with a single-phase AC power and three-stage motors used in combination with a three-phase AC power supply. A single-phase motor could be operated by simply connecting it to a single-phase power via the supplied capacitor. A three-phase motor will not require a capacitor. All you need is for connecting the motor right to a three-stage AC power supply.
The new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly suitable applications for the new range are those that 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 creation requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings.
