The high-end zero backlash planetary gearbox economy lines GSN & GFE combine powerful 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 has been especially designed to reach high torques that beat the competition for devices of the same size. All planetary carriers are produced as a cage created from solid material. This increases tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety relative to protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The concentrate on production in precision gears is tighter tolerances, so all over the gear will be a tighter, more specific suit. And the tighter match means much less play in the gear teeth, which is the cause of backlash in the first place. Of training course, precision gears are more expensive, if the application demands high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. For pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a huge impact on the quantity of backlash. So for instance, some gear types such as stress 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. Because of the lower torque values, the input stage is certainly dimensionally smaller compared to the output stage. Its short design makes the GSD range the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is required. The flange result creates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line means high performance in combination with low backlash and high precision. Its robust, one-piece housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB range; the right angle shape makes the GSBL series an ideal match for all powerful 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 in combination with a single-stage AC power and three-phase motors used with a three-stage AC power supply. A single-phase motor can be operated by simply linking it to 
a single-phase power supply via the provided 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 brand 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 ideal applications for the new range are those which place the highest 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 are equipped with precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
