The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing offers been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases calm operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water security relative to protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears can be tighter tolerances, so all over the gear will be a tighter, more specific match. And the tighter suit means less play in the gear teeth, which may be the cause of backlash to begin with. Of program, precision gears are more expensive, but if the application demands high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure the teeth mesh tightly together. That is typically completed by shortening the center distance between gears. For pre-loading, this could be done using a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the type 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. Due to the lower torque values, the input stage is certainly dimensionally smaller than the output stage. Its short style makes the GSD range the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it an ideal fit for highly worm drive servo dynamic applications where highest positioning and acceleration accuracy is required. The flange output produces 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 housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range provide same advantages as the GSB line; the right angle form makes the GSBL range an ideal 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 in combination with a single-stage AC power supply and three-phase motors used in combination with a three-phase AC power. A single-phase motor could be operated by simply connecting it to a single-phase power 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) along with the high-end economy GSN and GFE lines. Particularly suitable applications for the new range are those that place the highest demands on positioning accuracy, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and full needle bearings.
