The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped 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 worm drive servo china competition for devices of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases silent operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water safety in accordance with protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The concentrate on production in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more specific fit. And the tighter match means less play in the gear teeth, which is the cause of backlash in the first place. Of training course, precision gears are more expensive, if the application demands high accuracy, after that 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 performed by shortening the guts distance between gears. For pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a huge impact on the amount 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. Because of the lower torque ideals, the input stage is usually dimensionally smaller compared to the result stage. Its short style makes the GSD range the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and speed accuracy is required. The flange output produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available 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 allows for 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 line; the right angle shape makes the GSBL collection 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-phase motors used in combination with a single-phase AC power and three-stage 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 supply via the supplied capacitor. A three-phase motor does not require a capacitor. All you have to is for connecting the motor directly 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 suitable applications for the new range are those that place the highest demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings.
