The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing has been especially made to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water safety in accordance with protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all around the gear will be a tighter, more exact match. And the tighter match means less play in the apparatus teeth, which is the cause of backlash to begin with. Of program, precision gears are more expensive, if the application demands high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to make sure the teeth mesh tightly together. That is typically done by shortening the center distance between gears. For pre-loading, this can be done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a huge impact on the amount of backlash. So for example, some gear types such as strain wave gears, or harmonic gear drives, have zero backlash.
The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Because of the lower torque values, the input stage is usually dimensionally smaller than the result stage. Its short style makes the GSD series the perfect 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 rate accuracy is required. The flange result creates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or higher. The GSB line stands for high performance in combination 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 line provide same advantages as the GSB series; the right angle shape makes the GSBL line an ideal match for all powerful applications where space is bound.
