The high-end economy lines GSN & GFE combine powerful with financial 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 designed to reach high torques that defeat the competition for products of the same size. All planetary carriers are produced as a cage created from solid material. This increases noiseless operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water security relative to protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is certainly tighter tolerances, so all around the gear is a tighter, more specific match. And the tighter suit means much less play in the servo planetary gearbox apparatus teeth, which is the trigger of backlash to begin with. Of training course, precision gears are more expensive, but if the application calls for high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to ensure one’s teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. For pre-loading, this is often done using a spring mechanism to carry the gears firmly set up. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the amount of backlash. So for instance, some gear types such as stress wave gears, or harmonic equipment drives, possess 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 can be dimensionally smaller compared to the output stage. Its short design makes the GSD range the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and acceleration accuracy is necessary. The flange output creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line means high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range 
provide same advantages as the GSB line; the right angle shape makes the GSBL line 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 include single-stage motors used with a single-stage AC power and three-phase motors used in combination with a three-phase AC power. A single-phase motor could be operated by simply connecting it to a single-phase power 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) along with the high-end economy GSN and GFE lines. Particularly ideal applications for the new range are those that place the highest demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines include precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
