The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing provides been especially designed to reach high torques that beat the competition for devices of the same size. All planetary carriers are manufactured 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 band ensures maximum dirt and splash water protection relative to protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears can be tighter tolerances, so all around the gear will be a tighter, more specific suit. And the tighter fit means much less play in the apparatus teeth, which is the cause of backlash to begin with. Of training 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, a simple way to reduce backlash is to ensure one’s teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount of backlash. So for instance, some equipment 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. Because of the lower torque ideals, the input stage is definitely dimensionally smaller compared to the output stage. Its short style makes the GSD collection the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and velocity accuracy is required. The flange result creates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in mixture 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 form makes the GSBL series the perfect match for all powerful applications where space is bound.
