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 full needle bearing has been especially designed to reach high torques that defeat the competition for products of the same size. All planetary carriers are manufactured as a cage made from solid material. This increases silent operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water safety relative to protection course IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is certainly tighter tolerances, therefore all around the gear will be a tighter, more precise match. And the tighter fit means less play in the gear teeth, which is the cause of backlash in the first place. Of training 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, an easy way to lessen backlash is to make sure one’s teeth mesh tightly together. This is typically carried out by shortening the center distance between gears. For pre-loading, this can be done utilizing 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 type 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 insight stage is definitely dimensionally smaller than the result stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it the perfect fit for highly dynamic applications where highest positioning and acceleration accuracy is necessary. The flange output produces 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 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 powerful applications where space is bound.
