The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing offers been especially made to reach high torques that defeat the competition for products of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases peaceful operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water protection in worm drive servo accordance with protection class IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is certainly tighter tolerances, so all around the gear will be a tighter, more precise fit. And the tighter match means much less play in the apparatus teeth, which is the cause of backlash in the first place. Of program, precision gears are more expensive, but 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 one’s teeth mesh tightly together. That is typically done by shortening the guts distance between gears. As for pre-loading, this could be done using a spring mechanism to carry the gears firmly in place. This also eliminates the play between the gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for example, some equipment 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 ideals, the input stage is usually dimensionally smaller compared to the result stage. Its short design makes the GSD range the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange result generates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available 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 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 range; the right angle shape 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-stage AC power supply and three-phase motors used with a three-stage AC power supply. 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 have to is to connect the motor directly 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 suitable applications for the brand new range are those which place the best demands on positioning precision, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest production requirements – all lines include precision surface helical gearing, single-piece planetary carriers and full needle bearings.
