The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases silent operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security relative to protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears is tighter tolerances, so all around the gear will be a tighter, more specific suit. And the tighter fit means less play in the gear teeth, which may be the cause of backlash to start with. Of course, precision gears are more costly, but if the application calls for high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically completed by shortening the guts distance between gears. As for pre-loading, this could be done using a spring mechanism to carry the gears firmly set up. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used can also have a large impact on the quantity of backlash. So for example, some gear 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. Due to the lower torque ideals, the input stage can be dimensionally smaller compared to the output stage. Its short design makes the GSD collection the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it an ideal fit for highly powerful 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 optionally available in sizes with 90 mm diameter or higher. 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 series provide same advantages as the GSB series; the right angle form makes the GSBL line the perfect match for all dynamic applications where space is limited.
