The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing has been especially made to reach high torques that defeat the competition for devices of the same size. All planetary carriers are produced as a cage made from solid material. This increases peaceful operating characteristics while at exactly the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water safety relative to protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is certainly tighter tolerances, so all over the gear is a tighter, more precise match. And the tighter suit means much less play in the apparatus teeth, which is the cause of backlash in the first place. Of program, precision gears are more costly, if the application calls for high accuracy, then precision gearing could be the way to go.
From a gear design perspective, an easy way to reduce backlash is to make sure the teeth mesh tightly together. This is typically performed by shortening the center distance between gears. For pre-loading, this is often done using a spring mechanism to hold the gears firmly set up. This also eliminates the play between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the quantity 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. Due to the lower torque values, the input stage is definitely dimensionally smaller than the output stage. Its short style makes the GSD line the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange result produces highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective in sizes with 90 mm servo planetary gearbox diameter or more. The GSB line means 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 line; the right angle form makes the GSBL line the perfect 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 equipment motors include single-phase motors used with a single-stage AC power and three-stage motors used in combination with a three-phase AC power supply. A single-phase motor could be operated by simply linking it to a single-phase power supply 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-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 created to meet the highest creation requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
