The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing offers been especially made to reach high torques that beat the competition for models of the same size. All planetary carriers are produced as a cage made from solid materials. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water protection in accordance with protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all over the gear will be a tighter, more precise match. And the tighter suit means much less play in the gear teeth, which is the trigger of backlash in the first place. Of program, precision gears are more costly, but if the application demands high accuracy, then precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to ensure one’s teeth mesh zero backlash planetary gearbox tightly together. That is typically performed by shortening the guts distance between gears. As for pre-loading, this can be done using a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a large impact on the quantity of backlash. So for instance, some gear types such as strain 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. Because of the lower torque values, the input stage is definitely dimensionally smaller than the 
result stage. Its short style makes the GSD collection the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it the perfect fit for highly powerful applications where highest positioning and velocity accuracy is required. 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 higher. The GSB line stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range provide same advantages as the GSB line; the right angle shape makes the GSBL range an ideal match for all powerful applications where space is limited.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-phase motors used with a single-phase AC power and three-stage motors used in combination with a three-stage 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 will not need a capacitor. All you need is to connect the motor right 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 suitable applications for the brand new range are those that place the best demands on positioning precision, 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.
