The high-end economy lines GSN & GFE combine powerful 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 provides been especially designed to reach high torques that beat the competition for systems of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases silent operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security relative to protection class IP65 in every lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is tighter tolerances, so all around the gear is a tighter, more specific fit. And the tighter fit means less play in the apparatus teeth, which may be the cause of backlash in the first place. Of training course, precision gears are more costly, but if the application demands high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically performed by shortening the center distance between gears. For pre-loading, this could be done using a spring mechanism to carry 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 can also have a huge impact on the quantity of backlash. So for instance, some equipment types such as stress wave gears, or harmonic gear 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 is dimensionally smaller compared to the result stage. Its short style makes the GSD line the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it the perfect fit for highly dynamic applications where highest positioning and acceleration accuracy is necessary. The flange result generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line stands for 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 provide same advantages as the GSB range; the right angle shape makes the GSBL line the perfect match for all dynamic 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 in combination with a single-stage AC power and three-phase motors used with a three-stage AC power. A single-phase motor can be operated by worm drive servo china 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 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 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 made to meet the highest creation requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
