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 full needle bearing provides been especially made to reach high torques that beat the competition for units of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases silent operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water security in accordance with protection class IP65 in all lines.
One way to reduce backlash is by using precision gears. The concentrate on production in precision gears is usually tighter tolerances, so all around the gear will be a tighter, more exact fit. And the tighter fit means less play in the apparatus teeth, which may be the cause of backlash in the first place. Of training course, precision gears are more expensive, if the application demands high accuracy, then precision gearing could 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 done by shortening the center distance between gears. As for pre-loading, this could be done using 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 type of gears used may also have a huge impact on the quantity of backlash. So for instance, some gear types such as stress wave gears, or harmonic equipment drives, have 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 certainly dimensionally smaller than the output stage. Its short design makes the GSD collection the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and rate accuracy is required. The flange result generates 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 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 range provide same advantages as the GSB range; the right angle form makes the GSBL range an ideal match for all dynamic applications where space is bound.
