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 entire needle bearing provides been especially made to reach high torques that beat the competition for systems of the same size. All planetary carriers are produced as a cage created from solid material. This increases tranquil 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 class IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears is definitely tighter tolerances, therefore all around the gear will be a tighter, more exact match. And the tighter match means much less play in the gear teeth, which is the trigger of backlash to start with. 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 lessen backlash is to make sure the teeth mesh tightly together. This is typically done by shortening the guts distance between gears. For pre-loading, this could 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 can also have a huge impact on the quantity of backlash. So for instance, some equipment types such as stress 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 definitely dimensionally smaller than the result stage. Its short style makes the GSD line the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD line 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 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 allows for 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 line the perfect match for all dynamic applications where space is limited.
