The high-end economy lines GSN & GFE combine powerful with financial 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 made to reach high torques that beat the zero backlash planetary gearbox competition for products of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water security in accordance with protection class IP65 in all 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 is a tighter, more exact fit. And the tighter fit means much less play in the gear teeth, which is the cause of backlash in the first place. Of training course, precision gears are more expensive, but if the application calls for high accuracy, then 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 done by shortening the center distance between gears. For pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount of backlash. So for example, some gear types such as stress 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 ideals, the input stage is certainly dimensionally smaller than the result stage. Its short design makes the GSD series the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange result produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection provide same advantages as the GSB series; the right angle form makes the GSBL line the perfect 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 equipment motors include single-phase motors used in combination with a single-stage AC power supply and three-stage 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 provided capacitor. A three-phase motor does not need a capacitor. All you need is for connecting the motor right 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 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 production requirements – all lines include precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
