The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing offers been especially designed to reach high torques that beat the competition for models of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water protection in accordance with protection class IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is definitely tighter tolerances, so all around the gear will be a tighter, more specific suit. And the tighter fit means much less play in the apparatus teeth, which is the cause of backlash to begin with. Of training course, precision gears are more expensive, but if the application demands high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically completed by shortening the guts distance between gears. For pre-loading, this can be done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the play between the gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a large impact on the amount of backlash. So for instance, some gear 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. Because of the lower torque ideals, the input stage is certainly dimensionally smaller compared to the output stage. Its short style makes the GSD series the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and rate accuracy is required. The flange output creates 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 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 offer the same advantages as the GSB collection; the right angle form makes the GSBL line an ideal 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-stage motors used in combination with a single-phase AC power and three-stage motors used with a three-phase AC power. A single-phase motor could be operated by simply linking it to a single-phase power supply 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-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) and also the high-end economy GSN and GFE lines. Particularly ideal applications for the brand new range are those which place the highest demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest worm drive servo china production requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
