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 provides been especially made to reach high torques that beat the competition for devices of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases noiseless operating characteristics while at exactly the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water safety relative to protection class IP65 in all lines.
One method to reduce backlash is to use precision gears. The focus on production in precision gears is usually tighter tolerances, so all over the gear will be a tighter, more exact fit. And the tighter match means 
much less play in the apparatus teeth, which is the trigger of backlash in the first place. Of training course, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design worm drive servo china perspective, an easy way to reduce backlash is to make sure one’s teeth mesh tightly together. That is typically done by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity of backlash. So for example, some gear 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. Because of the lower torque ideals, the input stage is dimensionally smaller than the result stage. Its short style makes the GSD range the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange result produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective 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 allows for a high 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 range; 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 tend to increase backlash.
AC motors and equipment 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 provided capacitor. A three-phase motor will not require a capacitor. All you need is for connecting 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 ideal applications for the new range are those that place the highest demands on positioning precision, operating noises, working 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.
