The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that beat the competition for devices of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water protection relative to protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all around the gear is a tighter, more exact fit. And the tighter match means less play in the gear teeth, which may be the cause of backlash in the first place. Of course, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to ensure the teeth mesh tightly together. That is typically done by shortening the guts distance between gears. For pre-loading, this is often done using a spring mechanism to hold the gears firmly in place. This also eliminates the perform between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for example, some equipment types such as strain 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 than the output stage. Its short design makes the GSD line the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is required. The flange result produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller worm drive servo 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 series offer the same advantages as the GSB collection; the right angle shape makes the GSBL series the perfect match for all powerful 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-phase motors used with a single-phase AC power and three-stage motors used in combination with a three-phase AC power. 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 require a capacitor. All you need is for connecting the motor right 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) 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 created to meet the highest creation requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
