The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing provides been especially designed to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage made from solid materials. 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 security relative to protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is definitely tighter tolerances, so all over the gear is a tighter, more exact suit. And the tighter fit means less play in the gear teeth, which may be the trigger of backlash to start with. Of program, precision gears are more costly, but if the application calls for high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, an easy way to lessen backlash is to ensure 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 utilizing 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 may also have a huge impact on the amount of backlash. So for instance, some equipment types such as strain 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 insight stage is usually dimensionally smaller compared to the output stage. Its short design makes the GSD range the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it an ideal fit for highly powerful applications where highest positioning and acceleration accuracy is required. The flange output generates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line means 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 series offer the same advantages as the GSB line; the right angle form makes the GSBL range the perfect match for all powerful applications where space is bound.
