The 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 entire needle bearing provides been especially made to reach high torques that worm drive servo china defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases quiet operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water protection in accordance with protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is definitely tighter tolerances, so all over the gear will be a tighter, more specific match. And the tighter suit means less play in the apparatus teeth, which may be the trigger of backlash in the first place. Of training course, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing may be the way to go.
From a gear design perspective, a simple way to reduce backlash is to make sure the teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. As for pre-loading, this is often done using a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the amount of backlash. So for example, some equipment types such as strain 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. Because of the lower torque values, the input stage is dimensionally smaller compared to the output stage. Its short design makes the GSD line the ideal 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 velocity accuracy is necessary. The flange output creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line means 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 collection provide same advantages as the GSB range; the right angle form makes the GSBL series 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 equipment motors include single-phase motors used with a single-phase AC power and three-phase 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 will not need a capacitor. All you need is to connect the motor directly 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) as well as the high-end economy GSN and GFE lines. Particularly suitable applications for 
the brand new range are those which place the highest demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
