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 made to reach high torques that defeat the competition for zero backlash planetary gearbox china devices of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases quiet 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 is a tighter, more specific 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, but if the application calls for high accuracy, then precision gearing may be the way to go.
From a gear design perspective, a simple way to reduce 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 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, 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 regular backlash of the GSD range makes it the perfect fit for highly dynamic applications where highest positioning and swiftness accuracy is required. The flange output generates highest torsional rigidity. For the lodging 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 offer the same advantages as the GSB collection; the right angle shape makes the GSBL collection an ideal match for all dynamic applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-phase motors used in combination with a single-stage AC power and three-phase motors used in combination with a three-stage AC power. A single-phase motor could be operated by simply linking it to a single-phase power via the supplied 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 gear), 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, working smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings.
