The high-end economy lines GSN & GFE combine high performance 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 offers been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage made from solid materials. This increases quiet operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dirt 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 production in precision gears is certainly tighter tolerances, so all around the gear will be a tighter, more specific 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 lessen backlash is to ensure the teeth mesh tightly together. That is typically done by shortening the center distance between gears. For pre-loading, this could be done utilizing a spring mechanism to hold 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. Because of the lower torque ideals, the input stage can be dimensionally smaller compared to the output stage. Its short design makes the GSD series the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and acceleration accuracy is required. 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 more. 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 collection; the right angle form makes the GSBL collection the perfect match for all powerful applications where space is bound.
