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 provides been especially designed to reach high torques that beat the competition for devices of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases silent operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water safety in accordance with protection class IP65 in all lines.
One way 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 precise match. And the tighter suit means much less play in the gear teeth, which may be the cause of backlash to begin with. Of course, precision gears are more expensive, but if the zero backlash planetary gearbox china application calls for high accuracy, then precision gearing may be the way to go.
From a gear design perspective, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically performed by shortening the center distance between gears. As for pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount of backlash. So for example, some equipment types such as stress wave gears, or harmonic equipment 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 is dimensionally smaller than the output stage. Its short style makes the GSD collection the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and swiftness accuracy is necessary. The flange output creates highest torsional rigidity. For the lodging of especially 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB range; the right angle shape makes the GSBL collection an ideal 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-phase motors used with a single-stage AC power and three-phase motors used in combination with a three-stage AC power supply. A single-phase motor can 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 need is to connect 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) along with the high-end economy GSN and GFE lines. Particularly suitable applications for the brand 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 creation requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings.
