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 offers been especially designed to reach high torques that beat the competition for units of the same size. All planetary carriers are produced as a cage made from solid materials. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water protection in accordance with protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all around the gear will be a tighter, more specific fit. And the tighter match means less play in the gear teeth, which may be the trigger of backlash in the first place. Of program, precision gears are more costly, but if the application demands high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure one’s teeth mesh tightly together. This is typically done by shortening the guts distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity of backlash. So for instance, some equipment types such as strain wave gears, or harmonic gear 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 is certainly dimensionally smaller than the output stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it the perfect fit for highly dynamic applications where highest positioning and acceleration accuracy is required. The flange output 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 higher. 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 collection provide same advantages as the GSB collection; the right angle shape makes the GSBL line an ideal match for all dynamic applications where space is limited.
