The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing offers 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 materials. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety in accordance with protection worm drive servo course IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears can be tighter tolerances, so all over the gear is a tighter, more specific suit. And the tighter fit means less play in the gear teeth, which is the cause of backlash to begin with. Of program, precision gears are more expensive, 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 ensure the teeth mesh tightly together. That is typically completed by shortening the center distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount of backlash. So for instance, some equipment types such as strain wave gears, or harmonic gear drives, possess 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 usually dimensionally smaller compared to the result stage. Its short style makes the GSD collection the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. The flange output 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 higher. The GSB line means high performance in combination 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 collection; the right angle shape makes the GSBL line the perfect match for all powerful applications where space is limited.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-phase motors used with a single-phase AC power supply and three-stage motors used with a three-stage AC power supply. A single-phase motor can be operated by simply linking it to a single-phase power via the supplied capacitor. A three-phase motor will not need a capacitor. All you need is for connecting the motor right 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 best demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest production requirements – all lines include precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
