The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical zero backlash planetary gearbox china ground gears, ensuring the very least noise level and smooth running. The entire needle bearing has been especially designed to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage made from solid material. This increases tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water security relative to protection class IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all around the gear is a tighter, more exact fit. And the tighter suit means much less play in the gear 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 equipment design perspective, a simple way to reduce backlash is to ensure the teeth mesh tightly together. That is typically performed by shortening the center distance between gears. For pre-loading, this can be done utilizing 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 type of gears used can also have a huge impact on the quantity 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. Because of the lower torque ideals, the input stage can be dimensionally smaller compared to the output stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and quickness 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 allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB collection; the right angle form makes the GSBL range 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-phase motors used with a single-phase AC power and three-phase motors used with a three-stage AC power supply. A single-phase motor can be operated by simply connecting it to a single-phase power via the supplied capacitor. A three-phase motor will not need a capacitor. All you have to is to connect the motor right to a three-stage AC power supply.
The 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 which place the highest demands on positioning precision, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and full needle bearings.
