The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing provides been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage created from solid material. This increases calm 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 all lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more precise fit. And the tighter match means much less play in the apparatus teeth, which may be the servo planetary gearbox trigger of backlash to begin with. Of program, precision gears are more costly, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to make sure the teeth mesh tightly together. This is typically done by shortening the guts distance between gears. For pre-loading, this can be 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 huge impact on the amount of backlash. So for instance, some equipment types such as strain 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 ideals, the input stage is dimensionally smaller than the output stage. Its short design makes the GSD range 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 generates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB series; the right angle form makes the GSBL line the perfect match for all dynamic applications where space is bound.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC motors and gear motors include single-stage motors used with a single-stage AC power and three-stage motors used in combination with a three-phase AC power supply. A single-phase motor can be operated by simply connecting it to a single-phase power supply via the provided capacitor. A three-phase motor does not require a capacitor. All you have to is for connecting the motor right to a three-phase 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 ideal applications 
for the new range are those that place the best demands on positioning accuracy, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest production requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
