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 offers been especially designed to reach high torques that defeat the competition for products of the same size. All planetary carriers are produced as a cage created from solid material. This increases peaceful operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water safety relative to protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is certainly 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 trigger of backlash to begin with. Of training course, precision gears are more expensive, if the application calls for high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, an easy way to reduce backlash is to ensure one’s teeth mesh tightly together. This is typically done by shortening the center distance between gears. For pre-loading, this is often done using a spring mechanism to hold the gears firmly set up. This also eliminates the play between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for example, some equipment 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 can be dimensionally smaller than the result stage. Its short style makes the GSD line 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 rate accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation 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 permits a high 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 shape makes the GSBL collection the perfect match for all powerful applications where space is bound.
