The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full needle bearing provides been especially made to reach high torques that beat the competition for units of the same size. All planetary carriers are produced as a cage made from solid materials. This increases calm operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water safety relative to protection course IP65 in every lines.
One way to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is certainly tighter tolerances, so all over the gear will be a tighter, more precise fit. 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 costly, if the application calls for high accuracy, then precision gearing may be the way to go.
From a gear design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. This is typically done by shortening the guts distance between gears. As for pre-loading, 
this can be done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a huge impact on the amount of backlash. So for example, some gear 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 input stage is definitely dimensionally smaller compared to the result stage. Its short style makes the GSD line the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD collection 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 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 combination 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 provide same advantages as the GSB range; the right angle form makes the GSBL collection an ideal match for all dynamic applications where space is limited.
