The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built 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 defeat the competition for devices of the same size. All planetary carriers are produced as a cage created from solid materials. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water protection relative to protection class IP65 in all lines.
One method to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more specific match. And the tighter suit 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 expensive, if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to make sure the teeth mesh tightly together. That is typically done by shortening the center distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity of backlash. So for example, some equipment types such as stress wave gears, or harmonic gear 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 is dimensionally smaller than the result stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it an ideal fit for highly powerful applications where servo planetary gearbox highest positioning and speed accuracy is necessary. The flange result creates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective 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 permits a high 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 line; the right angle form makes the GSBL series the perfect match for all powerful applications where space is bound.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-phase motors used in combination with a single-phase AC power and three-phase motors used in combination with a three-phase AC power. A single-phase motor can 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 to connect the motor directly to a three-phase AC power supply.
The new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly appropriate applications for the new range are those which place the highest demands on positioning precision, operating noises, working 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 full needle bearings.
