The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially designed to reach high torques that beat the competition for units of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases quiet operating characteristics while at 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 course IP65 in every lines.
One way to reduce worm drive servo backlash is to use precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all around the gear is a tighter, more precise fit. And the tighter fit means less play in the apparatus teeth, which may be the trigger of backlash to begin with. Of training course, precision gears are more expensive, if the application calls for high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, an easy way to reduce backlash is to make sure one’s teeth mesh tightly together. That 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 set up. This also eliminates the enjoy 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 gear drives, possess zero backlash.

The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Due to the lower torque ideals, the input stage is definitely dimensionally smaller than the result stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and swiftness accuracy is necessary. The flange result generates 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 mixture 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 collection offer the same advantages as the GSB series; the right angle form makes the GSBL range the perfect match for all powerful applications where space is bound.

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-stage AC power supply and three-stage motors used with a three-phase AC power. A single-phase motor could be operated by simply linking it to a single-phase power via the provided capacitor. A three-phase motor does not need a capacitor. All you have to is for connecting the motor directly 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) along with the high-end economy GSN and GFE lines. Particularly suitable applications for the 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 designed to meet the highest production requirements – all lines include precision surface helical gearing, single-piece planetary carriers and full needle bearings.
