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 defeat the competition for units of the same size. All planetary carriers are produced as a cage created from solid materials. This increases quiet 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 course IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears can be tighter tolerances, so all around the gear is a tighter, more specific fit. And the tighter suit means much less play in the gear teeth, which may be the cause of backlash in the first place. Of course, precision gears are more expensive, if the application demands high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to make sure the teeth mesh tightly together. This is typically completed by shortening the guts distance between gears. For pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity of backlash. So for example, 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 ideals, the input stage is dimensionally smaller than the output stage. Its short design makes the GSD series the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB collection; the right angle shape makes the GSBL collection an ideal match for all powerful applications where space is limited.
