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 entire needle bearing offers 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 tranquil 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 in accordance with protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears can be tighter tolerances, so all around the gear is a tighter, more specific match. And the tighter match means much less play in the apparatus teeth, which is the trigger of backlash to begin with. Of course, precision gears are more expensive, but if the application calls for high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. This is typically completed by shortening the center distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the amount of backlash. So for example, some equipment 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 insight stage is usually dimensionally smaller compared to the result stage. Its short style makes the GSD line the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it the perfect fit for highly dynamic applications where highest positioning and rate accuracy is necessary. The flange output produces 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection provide same advantages as the GSB range; the right angle shape makes the GSBL line the perfect match for all dynamic applications where space is limited.
