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 entire needle bearing offers been especially designed to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases peaceful 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 in accordance with protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all over the gear is a tighter, more exact suit. And the tighter match means much less play in the apparatus teeth, which is the trigger of backlash to begin with. Of training course, 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, an easy way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically completed by shortening the guts distance between gears. As for pre-loading, this could be done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the play between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the amount of backlash. So for example, some equipment types such as stress wave gears, or harmonic equipment drives, possess 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 definitely dimensionally smaller compared to the result stage. Its short design makes the GSD collection the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD range makes it the perfect fit for highly dynamic applications where highest positioning and quickness accuracy is required. The flange result worm drive servo produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective 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 line provide same advantages as the GSB collection; 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 tend to increase backlash.
AC motors and gear motors include single-phase motors used with a single-phase AC power and three-phase motors used in combination 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 supplied capacitor. A three-phase motor will not need a capacitor. All you have to is for connecting the motor directly to a three-phase AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly appropriate 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 made to meet the highest creation requirements – all lines include precision ground helical gearing, single-piece planetary 
carriers and complete needle bearings.
