The worm drive servo high-end economy 
lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing provides been especially made to reach high torques that beat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases silent operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water safety relative to protection class IP65 in every lines.
One way to reduce backlash is by using precision gears. The focus on production in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more exact match. And the tighter suit means much less play in the gear teeth, which is the cause of backlash in the first place. Of program, precision gears are more costly, but if the application calls for high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure the teeth mesh tightly together. That is typically done by shortening the guts distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly in place. This also eliminates the play between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a huge impact on the quantity of backlash. So for instance, some equipment types such as stress wave gears, or harmonic gear 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 ideals, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD range the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it the perfect fit for highly powerful applications where highest positioning and swiftness accuracy is required. The flange result creates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line stands for 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 collection offer the same advantages as the GSB series; the right angle shape makes the GSBL collection an ideal match for all dynamic applications where space is limited.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend 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 in combination with a three-stage 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 need a capacitor. All you need is for connecting the motor right to a three-stage AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) along with the high-end economy GSN and GFE lines. Particularly suitable applications for the brand new range are those that place the best demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
