The high-end economy lines GSN & GFE zero backlash planetary gearbox combine high performance with financial 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 designed to reach high torques that beat the competition for units of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water security relative to protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more precise suit. And the tighter fit means less play in the apparatus 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, after that precision gearing could be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. That is typically done by shortening the guts distance between gears. For pre-loading, this can be done utilizing a spring mechanism to hold 
the gears firmly set up. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount of backlash. So for instance, 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 output stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. 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 line provide same advantages as the GSB line; the right angle form makes the GSBL series the perfect match for all powerful 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-phase AC power supply and three-phase 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 supply via the supplied capacitor. A three-phase motor does not need a capacitor. All you have to 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 equipment), 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 which place the highest demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines include precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
