The high-end economy lines GSN & GFE combine powerful 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 made to reach high torques that defeat the competition for models of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases calm operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water protection in accordance with protection class IP65 in all lines.
One way to reduce backlash is by using precision gears. The focus on production in precision gears can be tighter tolerances, so all around the gear will be a tighter, more specific fit. And the tighter match means much less play in the apparatus teeth, which is the cause of backlash in the first place. Of training course, precision gears are more costly, if the application demands high accuracy, then precision gearing may be the way to go.
From a gear design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. For pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity 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. Due to the lower torque ideals, the input stage is dimensionally smaller than the output stage. Its short style makes the GSD range the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it the perfect fit for highly powerful applications where highest positioning and acceleration accuracy is necessary. The flange output generates 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 means high performance in combination 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 series offer the same advantages as the GSB series; the right angle shape makes the GSBL series the perfect match for all powerful applications where space is limited.
