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 has been especially made to reach high torques that beat the competition for products of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases calm operating characteristics while at exactly the same time improving positioning precision 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 concentrate on manufacturing in precision gears is tighter tolerances, so all over the gear is a tighter, more exact match. And the tighter suit means less play in the apparatus teeth, which is the cause of backlash in the first place. Of program, precision gears are more expensive, but if the application calls for high accuracy, then precision gearing could be the way to go.
From a gear design perspective, an easy way to lessen backlash is to make sure the teeth mesh tightly together. This is typically completed 
by shortening the center distance between gears. For pre-loading, this could be done using a spring mechanism to hold the gears firmly set up. This also eliminates the perform between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount of backlash. So for instance, some equipment types such as stress wave gears, or harmonic gear drives, possess 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 definitely dimensionally smaller than the result stage. Its short style makes the GSD line the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and acceleration accuracy is necessary. The flange result produces highest torsional rigidity. For the lodging 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 mixture 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 line provide same advantages as the GSB range; the right angle form makes the GSBL range an ideal match for all dynamic applications where space is limited.
The opportunities are countless with zero backlash planetary gearbox!
