The high-end economy lines GSN & GFE combine high performance 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 material. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water safety relative to protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is usually tighter tolerances, so all over the gear is a tighter, more precise fit. And the tighter match means less play in the apparatus teeth, which is the trigger of backlash to start with. Of course, precision gears are more expensive, if the application demands high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically carried out by shortening the center distance between gears. For pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the perform between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity of backlash. So for example, some equipment types such as strain wave gears, or harmonic equipment drives, possess 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 insight stage is usually dimensionally smaller than the output stage. Its short style makes the GSD range the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and velocity accuracy is necessary. The flange output produces highest torsional rigidity. For the accommodation 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 mixture with low backlash and high precision. Its robust, one-piece housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range provide same advantages as the GSB line; the right angle shape makes the GSBL series the perfect match for all powerful applications where space is bound.
