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 will be a tighter, more specific match. And the tighter suit means less play in the gear teeth, which may be the cause of backlash in the first place. Of training course, precision gears are more expensive, 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 make sure one's teeth mesh tightly together. This is typically performed by shortening the center distance between gears. As for pre-loading, this can be done using a spring mechanism to carry the gears firmly set up. This also eliminates the play between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount of backlash. So for example, some gear types such as strain wave gears, or harmonic equipment drives, have zero backlash.

restricted applications. The low standard backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and swiftness 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 higher. The GSB line stands for high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB series; the right angle shape makes the GSBL series an ideal match for all powerful applications where space is limited.
