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 entire needle bearing has been especially made to reach high torques that defeat the competition for units of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water safety 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 can be tighter tolerances, so all over the gear will be a tighter, more exact match. And the tighter fit means less play in the gear teeth, which may be the trigger of backlash to begin with. Of program, precision gears are more expensive, but if the application calls for high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically completed by shortening the guts distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a large impact on the quantity of backlash. So for example, some equipment types such as strain wave gears, or harmonic equipment drives, have zero backlash.
The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Because of the lower torque ideals, the input stage is usually dimensionally smaller than the result stage. Its short style makes the GSD collection the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it an ideal fit for highly powerful applications where highest positioning and quickness accuracy is necessary. The flange result creates highest torsional rigidity. For the accommodation of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. 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 collection; the right angle form makes the GSBL range the perfect match for all powerful applications where space is bound.
