The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing provides 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 made from solid materials. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety relative to protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more precise fit. And the tighter match means much less play in the apparatus teeth, which may be the trigger of backlash in the first place. Of program, precision gears are more costly, if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to ensure the teeth mesh tightly together. This is typically done by shortening the guts distance between gears. As for pre-loading, this could be done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a huge impact on the amount of backlash. So for instance, some equipment types such as strain wave gears, or harmonic equipment drives, have zero backlash.

The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Due to the lower torque values, the input stage is worm drive servo usually dimensionally smaller compared to the result stage. Its short design makes the GSD line the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is required. The flange result generates highest torsional rigidity. For the lodging 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 mixture with low backlash and high precision. Its robust, one-piece housing permits 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 collection; the right angle form makes the GSBL series an ideal match for all powerful applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-stage motors used with a single-phase AC power supply and three-phase motors used with a three-phase AC power. A single-phase motor could be operated by simply linking it to a single-phase power via the provided capacitor. A three-phase motor will not require a capacitor. All you need is to connect the motor directly 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) along with the high-end economy GSN and GFE lines. Particularly suitable 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 made to meet the highest creation requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
