The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing provides been especially made 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 material. This increases tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water security relative to protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is usually tighter tolerances, so all over the gear is a tighter, more specific match. And the tighter fit means less play in the gear teeth, which may be the trigger of backlash to begin with. Of course, precision gears are more costly, if the application demands 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 one’s teeth mesh tightly together. This is typically completed 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 therefore eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the quantity 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. Due to the lower torque values, the input stage is certainly dimensionally smaller compared to the result stage. Its short style makes the GSD series the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD line makes it an ideal fit for highly powerful applications where highest positioning and quickness accuracy is necessary. The flange result generates highest torsional rigidity. For the accommodation of especially 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 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 form makes the GSBL series an ideal match for all powerful applications where space is limited.
