The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The 
full needle bearing offers been especially designed to reach high torques that beat the competition for devices of the same size. All planetary carriers are produced as a cage created from solid materials. This increases noiseless operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water security in accordance with protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on production in precision gears is usually tighter tolerances, so all around the gear is a tighter, more precise fit. And the tighter suit means less play in the apparatus teeth, which is the trigger of backlash in the first place. Of program, precision gears are more costly, if the application calls for high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure the teeth mesh tightly together. That is typically performed 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 play between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for example, some equipment 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. Because of the lower torque values, the input stage is certainly dimensionally smaller compared to the result stage. Its short design makes the GSD series the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and swiftness accuracy is zero backlash planetary gearbox required. The flange output creates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line stands for 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 line provide same advantages as the GSB series; the right angle shape makes the GSBL series an ideal match for all powerful 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 supply and three-phase 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 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-stage AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly suitable applications for the new range are those which place the highest demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines include precision surface helical gearing, single-piece planetary carriers and full needle bearings.
