The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that beat the competition for units of the same size. All planetary carriers are produced as a cage created from solid material. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety in accordance with protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all around the gear will be a tighter, more exact match. And the tighter suit means less play in the apparatus teeth, which may be the cause of backlash in the first place. Of training course, 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, an easy way to reduce backlash is to ensure one’s teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. As for pre-loading, this can be done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the quantity of backlash. So for example, some equipment types such as stress 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. Due to the lower torque ideals, the input stage is definitely dimensionally smaller compared to the result stage. Its short style makes the GSD series the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and swiftness accuracy is necessary. The flange result generates 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 provide same advantages as the GSB series; the right angle form makes the GSBL series 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 in combination with a single-phase AC power and worm drive servo china three-phase motors used with a three-stage 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 need a capacitor. All you have to is for connecting the motor right to a three-phase AC power supply.
The new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), 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 that place the best demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings.
