The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing offers 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 created from solid materials. This increases silent operating characteristics while at exactly the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water security in accordance with protection class IP65 in all lines.
One method to reduce backlash is to use precision gears. The concentrate on production in precision gears is definitely tighter tolerances, so all around the gear will be a tighter, more precise fit. And the tighter suit means less play in the gear teeth, which is the trigger of backlash to begin with. Of course, precision gears are more expensive, if the application demands high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. This is typically done by shortening the guts distance between gears. For pre-loading, this is often done utilizing 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 amount of backlash. So for instance, some gear types such as strain wave gears, or harmonic gear 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 usually dimensionally smaller compared to the result stage. Its short style makes the GSD series the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and velocity accuracy is required. The flange result creates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line stands for 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 line an ideal match for all powerful applications where space is limited.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC zero backlash planetary gearbox china motors and equipment motors include single-stage motors used with a single-stage AC 
power and three-stage motors used in combination with a three-phase AC power supply. A single-phase motor can be operated by simply connecting it to a single-phase power supply via the supplied capacitor. A three-phase motor does not need 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 equipment), GSB (inline) and GSBL (angle gear) along with the high-end economy GSN and GFE lines. Particularly suitable applications for the new range are those which place the highest demands on positioning precision, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest production requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
