The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth worm drive servo running. The entire needle bearing provides been especially designed to reach high 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 exactly the same time improving positioning precision and reducing backlash. Yet another 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 production in precision gears is usually tighter tolerances, so all around the gear will be a tighter, more specific match. And the tighter fit means less play in the apparatus teeth, which may be the cause of backlash to begin with. Of program, 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, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the amount of backlash. So for example, 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 values, the input stage can be dimensionally smaller than the output stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it an ideal fit for highly powerful applications where highest positioning and acceleration accuracy is necessary. The flange output generates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line means 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 provide same advantages as the GSB series; the right angle shape 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-stage AC power supply and three-phase 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 supplied capacitor. A three-phase motor does not need a capacitor. All you need is to connect the motor directly to a three-phase AC power supply.
The 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 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 floor helical gearing, single-piece planetary carriers and full needle bearings.
