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 zero backlash planetary gearbox defeat the competition for models of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water safety in accordance with protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on production in precision gears is definitely tighter tolerances, so all around the gear will be a tighter, more exact fit. And the tighter fit means much less play in the gear teeth, which may be the cause of backlash in the first place. Of training course, precision gears are more costly, if the application calls for 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 make sure the teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. As for pre-loading, this can be done using a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount 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. Due to the lower torque values, the input stage can be dimensionally smaller compared to the result stage. Its short style makes the GSD line the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and swiftness accuracy is necessary. The flange output produces 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 means high performance in combination with low backlash and high precision. Its robust, one-piece housing allows for 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 range; the right angle form makes the GSBL line 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 equipment motors include single-phase motors used in combination with a single-phase AC power supply and three-stage motors used with a three-phase AC power supply. A single-phase motor could be operated by simply connecting it to a single-phase power via the provided capacitor. A three-phase motor does not require a capacitor. All you have to is to connect 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) along with 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 designed to meet the highest production requirements – all lines include precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
