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 entire needle bearing offers been especially designed to reach high torques that defeat the competition for products of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases quiet 
operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water protection in accordance with protection class IP65 in all lines.
One method to reduce backlash is to use precision gears. The concentrate on production in precision gears is usually tighter tolerances, so all around the gear is a tighter, more exact suit. And the tighter suit means much less play in the apparatus teeth, which may be the cause of backlash to begin with. Of course, precision gears are more expensive, but if the application demands high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure one’s teeth mesh tightly together. That is typically completed by shortening the center distance between gears. For pre-loading, this could be done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a large impact on the quantity of backlash. So for instance, 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 ideals, the input stage is certainly dimensionally smaller than the output stage. Its short design makes the GSD range the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and acceleration accuracy is required. The flange result produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm 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 range offer the same advantages as the GSB line; the right angle shape makes the GSBL series the perfect match for all powerful 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-phase AC power supply and three-phase motors used in combination with a three-phase AC power supply. A single-phase motor could be operated by simply connecting it to a single-phase power supply via the supplied capacitor. A three-phase motor does not require a capacitor. All you need is for connecting the motor directly to a three-stage AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly appropriate applications for the new range are those which place the highest demands on positioning precision, operating noises, worm drive servo china running smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines include precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
