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 full needle bearing provides been especially designed to reach high torques that defeat the competition for units of the same size. All planetary carriers are produced as a cage created from solid materials. This increases quiet zero backlash planetary gearbox operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water protection in accordance with protection course 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 fit. And the tighter match 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 costly, if the application demands high accuracy, after that precision gearing may 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 carried out by shortening the guts distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly in place. 
This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for example, some gear 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. Due to the lower torque values, the input stage is dimensionally smaller than the output stage. Its short design makes the GSD series the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. The flange result creates 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 means high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the GSB collection; 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 have a tendency to increase backlash.
AC motors and gear motors include single-phase motors used with a single-phase AC power supply and three-stage motors used with a three-phase AC power supply. A single-phase motor can be operated by simply connecting it to a single-phase power via the supplied capacitor. A three-phase motor will not need a capacitor. All you need is to connect the motor right to a three-stage AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly ideal applications for the brand new range are those which place the best demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines include precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
