The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing provides been especially designed to reach high torques that beat the competition for models of the same size. All planetary carriers are produced as a cage created from solid materials. This increases tranquil operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water security relative to protection course IP65 in all lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is definitely tighter tolerances, so all over the gear is a tighter, more specific suit. And the tighter fit means less play in the gear teeth, which is the trigger of backlash to begin with. Of course, precision gears are more costly, if the application calls for high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to ensure the teeth mesh tightly together. This is typically performed by shortening the center 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 enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the amount of backlash. So for instance, some gear 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. Because of the lower torque ideals, the input stage is dimensionally smaller than the output stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and velocity accuracy is required. The flange output 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 allows for a high 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 collection; the right angle shape makes the GSBL line an ideal match for all powerful applications where space is limited.
