The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing provides been especially made 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 materials. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water protection in accordance with protection class IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on production in precision gears is certainly tighter tolerances, so all around the gear will be a tighter, more specific suit. And the tighter suit means less play in the apparatus teeth, which may be 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 may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. This is typically performed by shortening the center distance between gears. As for pre-loading, this is often 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 may also have a large impact on the quantity of backlash. So for example, some gear 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 ideals, the input stage is usually dimensionally smaller than the output stage. Its short style makes the GSD collection the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it the perfect fit for highly powerful applications where highest positioning and rate accuracy is necessary. The flange result generates highest torsional rigidity. For the accommodation 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 mixture 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 collection provide same advantages as the GSB range; the right angle form makes the GSBL line the perfect 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 gear motors include single-phase motors used with a single-phase AC power and three-stage motors used with a three-phase AC power supply. A single-phase motor can be operated by simply linking it to a single-phase power supply via the provided capacitor. A three-phase motor will not require a capacitor. All you need is for connecting the motor right to a three-stage 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 that 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 servo planetary gearbox requirements – all lines include precision floor helical gearing, single-piece planetary carriers and full needle bearings.
