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 full needle bearing provides been especially made to reach high torques that beat the competition for models of the same size. All planetary carriers are produced as a cage made from solid material. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water protection relative to protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all around the gear will be a tighter, more exact suit. And the tighter match means less play in the apparatus teeth, which is the cause of backlash to begin with. Of course, precision gears are more expensive, but if the application demands high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. That is typically done by shortening the guts distance between gears. For zero backlash planetary gearbox pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the perform between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a huge impact on the amount of backlash. So for example, some equipment types such as strain wave gears, or harmonic gear 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 values, the input stage is usually dimensionally smaller compared to the result stage. Its short style makes the GSD collection the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. The flange output produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line means high performance in combination 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 collection offer the same advantages as the GSB collection; the right angle shape makes the GSBL line the perfect match for all powerful applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-phase motors used in combination with a single-phase AC power supply and three-phase motors used in combination with a three-phase 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 will not require a capacitor. All you need is for connecting the motor right to a three-phase 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 that place the best demands on positioning accuracy, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and full needle bearings.
