The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing offers been especially designed to reach high torques that defeat the competition for devices of the same size. All planetary carriers are produced as a cage made from solid materials. This increases calm operating characteristics while at exactly the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security relative to protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears can be tighter zero backlash planetary gearbox tolerances, so all around the gear will be a tighter, more exact fit. And the tighter match means less play in the gear teeth, which may be the trigger of backlash to begin with. Of program, precision gears are more costly, if the application calls for high accuracy, after that precision gearing may 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 done by shortening the center distance between gears. For pre-loading, this is often done using a spring mechanism to hold the gears firmly set up. This also eliminates the play between the gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for example, some equipment types such as stress 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. Because of the lower torque ideals, the input stage can be dimensionally smaller than the result stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. 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 higher. The GSB line means 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 range offer the same advantages as the GSB range; the right angle form makes the GSBL series the perfect 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-phase AC power supply and three-phase motors used with a three-phase AC power. 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 new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly appropriate applications for the new range are those that place the highest demands on positioning precision, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
