The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing has been especially designed to reach high torques that beat the competition for products 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. An additional shaft sealing band ensures maximum dirt and splash water safety relative to protection class IP65 in all lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is definitely tighter tolerances, so all over the gear is a tighter, more exact suit. And the tighter fit 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 gear design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. That is typically done by shortening the guts distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly set up. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for example, some gear types such as strain 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 certainly dimensionally smaller compared to the result stage. Its short style makes the GSD collection the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and quickness accuracy is necessary. The flange result 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 permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line offer the same advantages as the GSB range; the right angle form makes the GSBL collection the perfect match for all powerful applications where space is limited.
