The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing offers been especially designed to reach high torques that beat the competition for models of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases silent operating characteristics while at the same time improving positioning precision and servo planetary gearbox reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water safety relative to protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears is 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 is the cause of backlash in the first place. Of training course, precision gears are more costly, but if the application demands high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. For pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount of backlash. So for example, some gear types such as strain 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 can be dimensionally smaller than the result stage. Its short design makes the GSD collection the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and acceleration accuracy is necessary. The flange result produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. 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 series offer the same advantages as the GSB line; the right angle shape makes the GSBL series 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 equipment motors include single-stage motors used in combination with a single-stage AC power and three-phase motors used with a three-phase AC power supply. 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 need 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) as well as the high-end economy GSN and GFE lines. Particularly ideal applications for the brand new range are those 
which place the highest demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest production requirements – all lines include precision surface helical gearing, single-piece planetary carriers and full needle bearings.
