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 full needle bearing provides been especially designed to reach high torques that defeat the competition for products of the same size. All planetary carriers are produced as a cage created from solid material. This increases peaceful operating characteristics while at the same time servo planetary gearbox improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water security relative to protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears can be tighter tolerances, so all over the gear is a tighter, more specific fit. And the tighter fit means less play in the apparatus teeth, which is the cause of backlash to begin with. Of program, precision gears are more costly, but if the application demands high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to ensure the teeth mesh tightly together. That is typically performed by shortening the guts distance between gears. As for pre-loading, this could be done using a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the amount 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 certainly dimensionally smaller than the result stage. Its short style makes the GSD range the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation of particularly 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 higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the GSB series; the right angle form makes the GSBL series the perfect match for all dynamic applications where space is bound.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-stage motors used in combination with a single-stage AC power and three-stage motors used with a three-stage AC power. A single-phase motor can be operated by simply linking it to a single-phase power via the provided capacitor. A three-phase motor will not need a capacitor. All you have to is to connect the motor right 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) along with the high-end economy GSN and GFE lines. Particularly ideal applications for the brand new range are those that place the best demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest production requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings.
