The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage created from solid material. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust and worm drive servo splash water safety in accordance with protection course IP65 in all lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all over 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, if the application demands high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, a simple way to reduce backlash is to make sure one’s teeth 
mesh tightly together. This is typically completed by shortening the center distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used can 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. Due to the lower torque ideals, the input stage is dimensionally smaller compared to the output stage. Its short design makes the GSD line the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is required. The flange result produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. 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 line; the right angle shape makes the GSBL collection 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-phase motors used in combination with a single-phase AC power supply and three-stage motors used with a three-stage AC power supply. A single-phase motor can 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 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) as well as the high-end economy GSN and GFE lines. Particularly appropriate applications for the brand 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 made to meet the highest creation requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and full needle bearings.
