The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially designed to reach high torques that beat the competition for products of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases worm drive servo peaceful operating characteristics while at exactly the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water safety in accordance with protection class IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears can be tighter tolerances, so all around the gear is a tighter, more precise match. And the tighter match means much less play in the apparatus teeth, which may be the trigger of backlash in the first place. Of program, precision gears are more expensive, but 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 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 is often done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for instance, some gear types such as strain 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 certainly dimensionally smaller than the output stage. Its short style makes the GSD collection the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and swiftness accuracy is necessary. The flange result creates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits 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 series the perfect match for all dynamic applications where space is limited.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-stage motors used with a single-phase AC power supply and three-phase motors used with a three-phase AC power. A single-phase motor can be operated by simply linking it to a single-phase power via the supplied capacitor. A three-phase motor does not require a capacitor. All you need is to connect the motor directly 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) as well as the high-end economy GSN and GFE 
lines. Particularly suitable applications for the brand new range are those that 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 are equipped with precision floor helical gearing, single-piece planetary carriers and full needle bearings.
