The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing has been especially made to reach high torques that beat the competition for systems of the same size. All planetary carriers are produced as a cage created from solid materials. This increases noiseless operating characteristics while at the same time improving positioning servo planetary gearbox precision and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water safety in accordance with protection course IP65 in all lines.
One way to reduce backlash is by using precision gears. The focus on production in precision gears is definitely tighter tolerances, so all around the gear is a tighter, more specific suit. And the tighter match means much less play in the apparatus teeth, which is the trigger of backlash in the first place. Of course, precision gears are more expensive, 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 ensure the teeth mesh tightly together. This is typically performed by shortening the center distance between gears. For pre-loading, this is often done using a spring mechanism to carry the gears firmly set up. This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the amount of backlash. So for example, some equipment types such as stress 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 ideals, the input stage is definitely dimensionally smaller than the output stage. Its short style makes the GSD line the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and quickness accuracy is required. The flange result generates highest torsional rigidity. For the lodging of particularly 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 allows for a higher 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 shape makes the GSBL series an ideal match for all dynamic applications where space is bound.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-stage motors used in combination with a single-stage AC power supply and three-stage motors used 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 provided capacitor. A three-phase motor does not require a capacitor. All you have to is for connecting the motor directly to a three-stage AC power supply.
The new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly ideal 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 created to meet the highest creation requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings.
