The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing has 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 tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt 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 can be tighter tolerances, so all over the gear will be a tighter, more specific suit. And the tighter suit means less play in the apparatus teeth, which is the cause of backlash to begin with. Of training course, precision gears are more expensive, if the application demands high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. This is typically completed by shortening the center distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a large impact on the amount of backlash. So for instance, some gear types such as strain wave gears, or harmonic equipment worm drive servo 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 ideal high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and swiftness accuracy is required. The flange output produces 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 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 collection offer the same advantages as the GSB collection; the right angle form makes the GSBL line 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 gear motors include single-phase motors used in combination with a single-phase AC power and three-phase motors used in combination with a three-stage AC power supply. A single-phase motor can be operated by simply linking it to a single-phase power supply via the supplied capacitor. A three-phase motor will not need a capacitor. All you need is for connecting the motor directly 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) 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 accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest production requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
