The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built 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 manufactured as a cage created from solid materials. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. An worm drive servo china additional shaft sealing ring ensures maximum dirt and splash water protection in accordance with protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all over the gear will be a tighter, more exact suit. And the tighter match means less play in the apparatus teeth, which may be the cause of backlash to begin with. Of course, precision gears are more expensive, if the application calls for high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, a simple way to reduce backlash is to make sure one’s teeth mesh tightly together. This is typically completed by shortening the center distance between gears. For pre-loading, this could be done using a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for instance, some gear types such as strain 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 values, the input stage can be dimensionally smaller than the output stage. Its short design makes the GSD range the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it the perfect fit for highly dynamic 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 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series offer the same advantages as the GSB collection; the right angle form makes the GSBL line an ideal match for all dynamic applications where 
space is bound.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-stage motors used with a single-stage AC power and three-phase motors used with a three-stage AC power. A single-phase motor could be operated by simply linking it to a single-phase power supply via the supplied capacitor. A three-phase motor will not require a capacitor. All you have to is to connect the motor right to a three-stage AC power supply.
The new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly ideal 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 made to meet the highest production requirements – all lines include precision ground helical gearing, single-piece planetary carriers and full needle bearings.
