The high-end economy lines GSN & GFE combine high performance 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 made to reach high torques that beat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water security in accordance with protection course IP65 in every lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all over the gear is a tighter, more precise fit. And the tighter match means much less play in the gear teeth, which may be the cause of backlash to begin with. Of training course, precision gears are more expensive, if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. For pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between the gear teeth and thus 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 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 values, the input stage can be dimensionally smaller compared to the output stage. Its short style makes the GSD line the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and quickness accuracy is required. The flange output generates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination with low backlash and high precision. Its robust, one-piece worm drive servo housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the GSB series; the right angle form makes the GSBL collection the perfect match for all powerful applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-stage motors used in combination with a single-phase AC power supply and three-stage motors used with a three-phase AC power. A single-phase motor can be operated by simply linking it to a single-phase power via the provided capacitor. A three-phase motor will not need a capacitor. All you have to is for connecting the motor right to a three-phase 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 ideal applications for the brand new range are those that place the highest demands on positioning precision, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest production requirements – all lines include precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
