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 entire needle bearing provides been especially made to reach high torques that beat the competition for products of the same size. All planetary carriers are produced 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 ring ensures maximum dirt and splash water safety relative to protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears is certainly tighter tolerances, so all around the gear will be a tighter, more specific fit. And the tighter suit means much less play in the gear teeth, which is the cause of backlash in the first place. Of program, precision gears are more costly, if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a worm drive servo simple way to reduce backlash is to make sure one’s teeth mesh tightly together. This is typically completed by shortening the center distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to hold 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 instance, some equipment 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 values, the input stage is usually dimensionally smaller than the result stage. Its short style makes the GSD series the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is required. The flange output generates 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 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 series offer the same advantages as the GSB range; the right angle shape makes the GSBL collection the perfect match for all powerful 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 with a single-phase AC power supply and three-stage motors used in combination with a three-phase AC power. A single-phase motor can be operated by simply linking it to a single-phase power supply via the supplied capacitor. A three-phase motor will not require a capacitor. All you need is to connect the motor right 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) and also the high-end economy GSN and GFE lines. Particularly ideal applications for the brand new range are those which place the highest demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest production requirements – all lines include precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
