The high-end economy lines GSN & GFE combine high performance 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 devices of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water security in accordance with protection servo planetary gearbox course IP65 in every lines.
One method to reduce backlash is to use precision gears. The focus on production in precision gears is usually tighter tolerances, so all over the gear is a tighter, more precise suit. And the tighter suit 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 expensive, if the application demands high accuracy, then precision gearing could 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. That is typically carried out by shortening the guts distance between gears. As for pre-loading, this could be done using a spring mechanism to hold the gears firmly set up. This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the amount of backlash. So for example, some gear types such as stress wave gears, or harmonic equipment drives, possess 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 is dimensionally smaller compared to the result stage. Its short design makes the GSD series the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it an ideal fit for highly dynamic applications where highest positioning and acceleration accuracy is required. The flange output generates highest torsional rigidity. For the lodging 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 permits a high 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 range; the right angle form makes the GSBL series an ideal match for all dynamic applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-phase motors used in combination with a single-stage AC power and three-stage motors used with a three-phase AC power. A single-phase motor can be operated by simply connecting it to a single-phase power via the supplied capacitor. A three-phase motor does not require a capacitor. All you have to is for connecting the motor directly 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 appropriate applications for the brand new range are those which place the best demands on positioning accuracy, operating noises, operating 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.
