The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing offers been especially made to reach high torques that beat the competition for models of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases quiet operating characteristics while at exactly the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water security relative to protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is tighter tolerances, so all around the gear will be a tighter, more exact fit. And the tighter fit means less play in the gear teeth, which is the cause of backlash to begin with. Of course, precision gears are more costly, if the application calls for high accuracy, then precision gearing could be the way to go.
From a gear design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. This is typically done by shortening the center distance between gears. For pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount of backlash. So for example, some gear 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 ideals, the input stage is certainly dimensionally smaller than the output stage. Its short design makes the GSD range the zero backlash planetary gearbox china perfect high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and acceleration 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 higher. The GSB line means 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 range provide same advantages as the GSB collection; the right angle form makes the GSBL collection the perfect match for all powerful 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 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 via the provided capacitor. A three-phase motor does not require 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 appropriate applications for the 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 production requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
