The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped 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 systems of the same size. All planetary carriers are produced as a cage created from solid material. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water safety relative to protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears is tighter tolerances, so all around the gear will be a tighter, more specific fit. And the tighter suit means much less play in the gear teeth, which may be the trigger 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 gear design perspective, an easy 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. As for pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the amount of backlash. So for example, some equipment types such as stress wave gears, or harmonic equipment 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 ideals, the input stage can be dimensionally smaller than the result stage. Its short design makes the GSD series the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and quickness accuracy is required. The flange output servo planetary gearbox creates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line stands for high performance in mixture 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 series provide same advantages as the GSB series; the right angle shape makes the GSBL collection an ideal match for all dynamic applications where space is limited.

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-stage motors used in combination with a three-phase AC power supply. A single-phase motor could be operated by simply connecting it to a single-phase power supply via the provided capacitor. A three-phase motor does not need a capacitor. All you need is for connecting the motor directly to a three-stage 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 that place the highest demands on positioning accuracy, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines include precision ground helical gearing, single-piece planetary carriers and full needle bearings.
