The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing has been especially designed 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 the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water safety relative to protection course IP65 in all lines.
One way to reduce backlash is by using precision gears. The concentrate on production in precision gears can be tighter tolerances, so all over the gear will be a tighter, more specific match. And the tighter suit means 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 calls for high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, a simple way to reduce 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 could be done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the play between the 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 gear types such as strain 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. Because of the lower torque values, the input stage is certainly dimensionally smaller than the result stage. Its short style makes the GSD range the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and acceleration accuracy is necessary. The flange output produces highest torsional rigidity. For the lodging of especially 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 mixture with low backlash and high precision. Its robust, one-piece housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the GSB range; the right angle shape makes the GSBL range an ideal match for all dynamic applications where space is bound.
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-stage motors used in combination with a three-stage AC power supply. A single-phase motor could be operated by simply connecting it to a single-phase power via the provided capacitor. A three-phase motor does not need 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 equipment), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly suitable applications for the new range are those that place the highest demands on positioning accuracy, operating zero backlash planetary gearbox china noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines include precision floor helical gearing, single-piece planetary carriers and full needle bearings.
