The high-end economy lines GSN & GFE combine high performance with economic 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 defeat the competition for products of the same size. All planetary carriers are produced as a cage created from solid material. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water protection relative to protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears is certainly tighter tolerances, so all around the gear is a tighter, more specific suit. And the tighter match means less play in the gear teeth, which is the trigger of backlash in the first place. Of training 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 one’s teeth mesh tightly together. This is typically carried out by shortening the center distance between gears. As for pre-loading, this could be done using a spring mechanism to hold the gears firmly in place. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a large impact on the amount of backlash. So for example, some equipment types such as strain wave gears, or harmonic gear drives, have 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 dimensionally smaller than the result stage. Its short style makes the GSD collection the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange output produces highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line means high performance in combination with low backlash and high precision. Its robust, one-piece housing permits 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 shape makes the GSBL range an ideal match for all powerful applications where space is limited.
