The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially made to reach high torques that beat the competition for products of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases calm operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water safety in accordance with protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The focus on production in precision gears is usually tighter tolerances, so all around the gear will be a tighter, more exact match. And the tighter fit means less play in the apparatus 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, then precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to make sure the teeth mesh tightly together. That is typically done by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform 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 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 values, the input stage is usually dimensionally smaller than the result stage. Its short design makes the GSD collection the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and acceleration accuracy is necessary. The servo planetary gearbox 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 permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection provide same advantages as the GSB line; the right angle shape makes the GSBL series the perfect match for all dynamic applications where space is bound.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-phase motors used in combination with a single-phase AC power supply and three-stage 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 provided capacitor. A three-phase motor does not need a capacitor. All you have to is to connect the motor directly to a three-stage 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 appropriate applications for the 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 designed to meet the highest production requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
