The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing has been especially designed to reach high zero backlash planetary gearbox torques that beat the competition for devices of the same size. All planetary carriers are produced as a cage created from solid material. This increases peaceful 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 in accordance with protection course 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 suit. And the tighter match means much less play in the apparatus teeth, which is 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 gear design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. That is typically performed by shortening the center distance between gears. For pre-loading, this is often done using a spring mechanism to carry the gears firmly set up. This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity of backlash. So for instance, some gear types such as strain wave gears, or harmonic gear drives, possess 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 usually dimensionally smaller compared to the output stage. Its short style makes the GSD line the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it an ideal fit for highly powerful applications where highest positioning and quickness accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation of particularly 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 combination 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 line offer the same advantages as the GSB collection; the right angle shape makes the GSBL collection 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 equipment motors include single-stage motors used in combination with a single-stage AC power supply and three-phase motors used in combination with a three-stage AC power supply. 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 need a capacitor. All you have to 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 equipment), GSB (inline) and GSBL (angle gear) along with the high-end economy GSN and GFE lines. Particularly ideal applications for the new range are those that place the best demands on positioning precision, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
