The high-end economy lines GSN & GFE combine powerful 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 created from solid material. This increases tranquil operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water protection relative to protection class IP65 in all lines.
One way to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more specific fit. And the tighter fit means much less play in the apparatus teeth, which may be the cause of backlash in the first place. Of course, precision gears are more costly, but if the application calls for high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically performed by shortening the center distance between gears. As for pre-loading, this is often done using a spring mechanism to hold the gears firmly in place. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount of backlash. So for example, some equipment types such as stress 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 design makes the GSD range the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and swiftness accuracy is necessary. The flange result creates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line stands for 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 zero backlash planetary gearbox angular gearboxes of the GSBL collection offer the same advantages as the GSB line; the right angle form makes the GSBL range the perfect 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-phase motors used in combination with a single-phase AC power and three-phase motors used in combination with a three-phase AC power. A single-phase motor can be operated by simply connecting it to a single-phase power supply 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-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) and also the high-end economy GSN and GFE lines. Particularly appropriate applications for the new range are those which place the highest demands on positioning precision, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest production requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings.
