The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing provides 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 material. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety in accordance with protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all around the gear is a tighter, more specific fit. And the tighter suit means less play in the gear teeth, which is the trigger of backlash in the first place. Of course, precision gears are more expensive, if the application demands high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly set up. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for example, some equipment types such as stress 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 certainly dimensionally smaller compared to the output stage. Its short style makes the GSD series the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD line makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is required. The flange output produces highest torsional rigidity. For the accommodation 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 provide same advantages as the GSB collection; the right angle shape makes the GSBL collection 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 worm drive servo include single-stage motors used with a single-stage AC power supply and three-stage motors used with a three-phase AC power supply. A single-phase motor can be 
operated by simply linking it to a single-phase power supply via the supplied capacitor. A three-phase motor will not require a capacitor. All you have to is for connecting the motor right to a three-stage AC power supply.
The 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 appropriate applications for the brand new range are those which place the best demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines include precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
