The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth worm drive servo china running. The entire needle bearing has been especially made to reach high torques that beat the competition for models of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases noiseless operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water protection in accordance with protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all over the gear is a tighter, more precise suit. And the tighter match means much less play in the gear teeth, which may be the trigger of backlash to begin with. Of training course, precision gears are more expensive, if the application calls for high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. That is typically done by shortening the center distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity of backlash. So for instance, some gear types such as strain 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. Because of the lower torque ideals, the input stage is certainly dimensionally smaller compared to the output stage. Its short style makes the GSD line the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it the perfect fit for highly dynamic applications where highest positioning and velocity accuracy is required. The flange output produces highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are elective 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 allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB series; the right angle form makes the GSBL range 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 equipment motors include single-stage motors used 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 supply via the provided capacitor. A three-phase motor does not require a capacitor. All you have to 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 equipment), 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 that 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.
