The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing offers been especially made 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 material. This increases silent operating characteristics while at the same time improving positioning precision and reducing backlash. Yet worm drive servo china another shaft sealing ring ensures maximum dirt and splash water security in accordance with protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is usually tighter tolerances, so all over the gear will be a tighter, more exact suit. And the tighter fit means less play in the apparatus teeth, which may be the cause of backlash to begin with. Of training course, precision gears are more expensive, if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to make sure one’s 
teeth mesh tightly together. This is typically done by shortening the center distance between gears. As for pre-loading, this could be done using a spring mechanism to carry the gears firmly set up. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for instance, 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 values, the input stage is certainly dimensionally smaller than 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 an ideal fit for highly powerful applications where highest positioning and velocity accuracy is required. The flange result produces highest torsional rigidity. For the accommodation 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 permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range provide same advantages as the GSB collection; the right angle form makes the GSBL collection an ideal match for all dynamic applications where space is bound.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC motors and gear motors include single-stage motors used in combination with a single-phase AC power and three-stage motors used in combination 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 require a capacitor. All you have to is to connect the motor right to a three-stage AC power supply.
The brand 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 which place the best demands on positioning accuracy, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest production requirements – all lines include precision floor helical gearing, single-piece planetary carriers and full needle bearings.
