The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing provides been especially made to reach high torques that defeat the competition for devices of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases silent operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water protection relative to protection class IP65 in every lines.
One method to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all around the gear is a tighter, more precise match. And the tighter fit means much less play in the apparatus teeth, which may be 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 equipment design perspective, a simple way to reduce backlash is to make sure one’s teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. For pre-loading, this can be 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 can also have a large impact on the amount of backlash. So for instance, some gear types such as stress 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. Because of the lower torque values, the input stage is dimensionally smaller compared to the result stage. Its short design makes the GSD series the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and acceleration 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 higher. The GSB line means 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 line offer the same advantages as the GSB line; the right angle form makes the GSBL collection an ideal match for all powerful applications where space is limited.
