The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also equipped with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing offers been especially made to reach high torques that defeat the competition for devices of the same size. All planetary carriers are produced as a cage made from solid material. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water security in accordance with protection class IP65 in every lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is usually tighter tolerances, so all around the gear will be a tighter, more specific fit. And the tighter suit means less play in the apparatus teeth, which is the cause of backlash in the first place. Of course, precision gears are more costly, but if the application demands high accuracy, after that precision gearing may be the way to go.
From a gear 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 center distance between gears. As for pre-loading, this could be done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a huge 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 ideals, the insight stage is definitely dimensionally smaller than the output stage. Its short design makes the GSD collection the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is required. The flange output creates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB line; the right angle form makes the GSBL line the perfect match for all powerful applications where space is limited.
