The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing offers been especially designed to reach high torques that beat the competition for products of the same size. All planetary carriers are produced as a cage made from solid material. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust 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 is usually tighter tolerances, so all over the gear will be a tighter, more exact suit. And the tighter fit means less play in the apparatus teeth, which may be the trigger of backlash to begin with. Of training course, 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 lessen backlash is to ensure one’s teeth mesh tightly together. That is typically done by shortening the center distance between gears. As for pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for instance, some equipment types such as strain 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. Due to the lower torque ideals, the input stage is usually 
dimensionally smaller than the output stage. Its short design makes the GSD range the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and velocity accuracy is required. The flange result produces highest torsional rigidity. For the accommodation of especially high axial loads, taper worm drive servo roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination 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 series; the right angle shape makes the GSBL range an ideal match for all dynamic applications where space is limited.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC motors and equipment motors include single-phase motors used with a single-stage AC power and three-stage motors used with a three-phase AC power supply. A single-phase motor can be operated by simply connecting it to a single-phase power via the supplied capacitor. A three-phase motor does not need a capacitor. All you need 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 gear), GSB (inline) and GSBL (angle gear) along with the high-end economy GSN and GFE lines. Particularly suitable applications for the brand new range are those that 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 are equipped with precision floor helical gearing, single-piece planetary carriers and full needle bearings.
