The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing offers been especially made to reach high torques that defeat the competition for devices of the same size. All planetary carriers are produced as a cage created from solid materials. This increases calm operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water security in accordance with protection course 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 precise suit. And the tighter fit means less play in the gear teeth, which is the trigger of backlash to begin with. Of course, precision gears are more expensive, but if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to make sure the teeth mesh tightly together. This is typically performed by shortening the guts distance between gears. For pre-loading, this could be done utilizing 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 quantity of backlash. So for example, some gear types such as zero backlash planetary gearbox stress wave gears, or harmonic gear 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 values, the input stage is usually dimensionally smaller compared to 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 the perfect fit for highly powerful applications where highest positioning and acceleration accuracy is necessary. The flange output creates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available 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 collection provide same advantages as the GSB range; the right angle form makes the GSBL collection the perfect match for all powerful applications where space is bound.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-stage motors used with a single-stage AC power supply and three-stage motors used in combination with a three-phase AC power. A single-phase motor can be operated by simply connecting it to a single-phase power supply via the supplied capacitor. A three-phase motor will not require a capacitor. All you have to is for connecting the motor directly to a three-stage AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly appropriate applications for the brand new range are those which place the best demands on positioning precision, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines include precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
