The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing has been especially made to reach high torques that beat the competition for units of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water safety relative to protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is usually tighter tolerances, so all over the gear is a tighter, more precise match. And the tighter fit means less play in the gear teeth, which is the trigger of backlash in the first place. Of program, precision gears are more expensive, if the application demands high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure the teeth mesh tightly together. That is typically done by shortening the center distance between gears. As for pre-loading, this is often done using a spring mechanism to carry the gears firmly in place. 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 quantity 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 insight stage is usually dimensionally smaller than the result stage. Its short design makes the GSD series the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange output generates 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 stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line offer the same advantages as the GSB range; the right angle form makes the GSBL line the perfect match for all powerful applications where space is limited.

worm drive servo is a trend that is slowly rising.
