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 entire needle bearing provides been especially designed to reach high torques that beat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid materials. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water security relative to protection class IP65 in every lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all around the gear is a tighter, more exact fit. And the tighter match means much less play in the gear teeth, which may be the cause of backlash to begin with. Of training course, precision gears are more costly, but if the application calls for high accuracy, then precision gearing may 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. This is typically carried out by shortening the center distance between gears. For pre-loading, this could be done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between the gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a huge impact on the quantity of backlash. So for example, 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 dimensionally smaller than the output stage. Its short design makes the GSD collection the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and velocity accuracy is required. The flange output produces highest torsional rigidity. For the lodging 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 combination with low backlash and high precision. Its robust, one-piece housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB collection; the right angle shape makes the GSBL collection an ideal match for all powerful applications where space is limited.
