The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing has been especially designed to reach high torques that beat the competition for devices of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases noiseless operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water security relative to protection course IP65 in all lines.
One way to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears can be tighter tolerances, so all over the gear is a tighter, more specific match. And the tighter match means much less play in the apparatus teeth, which may be the cause of backlash in the first place. Of course, precision gears are more costly, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. That is typically carried out by shortening the center distance between gears. For pre-loading, this is often done using a spring mechanism to carry the gears firmly set up. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the amount of backlash. So for example, some equipment types such as stress wave gears, or harmonic equipment drives, have zero backlash.
The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Because of the lower torque values, the input stage is usually dimensionally smaller compared to the result stage. Its short style makes the GSD line the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it an ideal fit for highly powerful applications where highest positioning and speed 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 more. The GSB line stands for 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 collection offer the same advantages as the GSB series; the right angle form makes the GSBL range the perfect match for all powerful applications where space is bound.
