The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing has been especially designed to reach high torques that defeat the competition for models of the same size. All servo planetary gearbox planetary carriers are manufactured as a cage created from solid materials. This increases silent operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security in accordance with protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is definitely tighter tolerances, so all around the gear is a tighter, more exact fit. And the tighter match means much less play in the apparatus teeth, which may be the trigger of backlash in the first place. Of program, precision gears are more costly, if the application demands high accuracy, then precision gearing may 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. This is typically performed by shortening the guts distance between gears. For pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the perform between the gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a huge impact on the quantity of backlash. So for example, some equipment types such as strain 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 is certainly dimensionally smaller compared to the output stage. Its short style makes the GSD range the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is required. The flange output produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination 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 range provide same advantages as the GSB series; the right angle form makes the GSBL range an ideal 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-stage motors used in combination with a single-stage AC power and three-stage motors used with a three-stage AC power. A single-phase motor can be operated by simply connecting it to a single-phase power supply via the provided capacitor. A three-phase motor will not need a capacitor. All you need is to connect the motor right to a three-stage 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 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 created to meet the highest creation requirements – all lines include precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
