The high-end economy lines GSN & GFE servo planetary gearbox combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing provides been especially designed to reach high torques that beat the competition for products of the same size. All planetary carriers are produced as a cage created from solid material. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water protection relative to protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is tighter tolerances, so all around the gear is a tighter, more precise fit. And the tighter match means less play in the gear teeth, which is the trigger of backlash in the first place. Of training course, precision gears are more costly, if the application calls for high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to make sure the teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. For pre-loading, this can be done using 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 large 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. Because of the lower torque ideals, the input stage is definitely dimensionally smaller than the output stage. Its short style makes the GSD range the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. The flange result generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line offer the same advantages as the GSB range; the right angle form makes the GSBL line the perfect 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 with a single-stage AC power supply and three-phase motors used with a three-stage AC power. A single-phase motor could be operated by simply linking it to a single-phase power supply via the supplied capacitor. A three-phase motor does not need a capacitor. All you have to is for connecting the motor directly 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) as well as the high-end economy GSN and GFE lines. Particularly appropriate applications for the brand new range are those that place the highest demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and full needle bearings.
