The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing offers been especially made to reach high torques that beat the competition for systems of the same size. All worm drive servo china planetary carriers are manufactured as a cage made from solid materials. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security relative to protection course IP65 in all lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all around the gear is a tighter, more precise match. And the tighter suit means much less play in the apparatus teeth, which is the trigger of backlash to begin with. Of course, precision gears are more costly, but if the application calls for high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to make sure the teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. As for pre-loading, this could be done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may 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. Due to the lower torque ideals, the input stage can be dimensionally smaller than the output stage. Its short style makes the GSD series the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and rate accuracy is necessary. The flange result generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination 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 offer the same advantages as the GSB collection; the right angle form makes the GSBL range an ideal 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-stage motors used in combination with a single-phase AC power and three-phase motors used with a three-phase AC power supply. A single-phase motor could be operated by simply connecting it to a single-phase power via the provided capacitor. A three-phase motor does not need a capacitor. All you have to is to connect the motor right to a three-phase AC power supply.
The brand 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 appropriate applications for the brand new range are those which place the best demands on positioning precision, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest production requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and full needle bearings.
