The high-end economy lines GSN & GFE combine powerful with economic 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 designed 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 peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water safety 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, therefore all around the gear will be a tighter, more specific match. And the tighter match means less play in the apparatus teeth, which may be the trigger of backlash to start with. Of training course, precision gears are more costly, if the application calls for high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, a simple way to reduce backlash is to ensure the teeth mesh tightly together. That is typically done by shortening the guts distance between gears. For pre-loading, this can be done using a spring mechanism to hold the gears firmly set up. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a huge impact on the quantity of backlash. So for example, some gear types such as strain 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 compared to the result stage. Its short style makes the GSD range the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and velocity accuracy is required. The flange output creates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are optionally available 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 allows for a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series offer the same advantages as the GSB collection; the right angle form makes the GSBL collection the perfect match for all powerful applications where space is bound.
