The high-end economy lines GSN & GFE combine powerful 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 has been especially designed to reach high torques that defeat the competition for systems of the same size. All planetary carriers are zero backlash planetary gearbox china produced as a cage made from solid material. This increases silent operating characteristics while at exactly 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 class IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is tighter tolerances, so all over the gear is a tighter, more precise fit. And the tighter match means less play in the gear teeth, which is the trigger of backlash in the first place. Of course, precision gears are more expensive, but 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 reduce backlash is to ensure the teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a large impact on the quantity of backlash. So for example, 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. Due to the lower torque values, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD range the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD series makes it 
the perfect fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange result generates highest torsional rigidity. For the lodging 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 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 provide same advantages as the GSB series; the right angle form makes the GSBL range the perfect match for all dynamic applications where space is bound.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC motors and gear motors include single-stage motors used with a single-phase AC power supply and three-stage motors used in combination with a three-stage AC power. 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 will not need a capacitor. All you need 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) and also the high-end economy GSN and GFE lines. Particularly appropriate applications for the new range are those that place the highest demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines include precision floor helical gearing, single-piece planetary carriers and full needle bearings.
