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 provides been especially designed to reach high torques that defeat the competition for units of the same size. All planetary carriers are produced as a cage made from solid material. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security relative to protection class IP65 in all lines.
One way to reduce backlash is by using precision gears. The concentrate on production in precision gears is tighter tolerances, so all around the gear is a tighter, more specific fit. And the tighter suit means less play in the apparatus teeth, which may be the cause of backlash to begin with. Of program, precision gears are more costly, if the application calls for high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure one’s teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity of backlash. So for instance, some gear types such as stress wave gears, or harmonic gear drives, have 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 can be dimensionally smaller than the result stage. Its short style makes the GSD line the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and rate accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line means high performance in mixture 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 angular gearboxes of the GSBL series offer the same advantages as the GSB range; the right angle form makes the GSBL line the perfect 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-phase motors used in combination with a single-phase 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 via the provided capacitor. A three-phase motor will not need a capacitor. All you need is for worm drive servo china connecting the motor right 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 suitable 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 designed to meet the highest production requirements – all lines include precision ground helical gearing, single-piece planetary carriers and full needle bearings.
