The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing offers been especially made to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases quiet operating characteristics while at exactly the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water protection relative to protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The focus on production in precision gears can be tighter tolerances, so all around the gear is a tighter, more exact suit. And the tighter match means much less play in the apparatus teeth, which may be the trigger of backlash in the first place. Of course, precision gears are more costly, if the application demands 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 the teeth mesh tightly together. This is typically performed by shortening the center distance between gears. As for pre-loading, this could be done using a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the quantity of backlash. So for instance, some equipment types such as strain 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. Due to the lower torque ideals, the input stage can be dimensionally smaller than the output stage. Its short style makes the GSD line the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD servo planetary gearbox series makes it the perfect fit for highly powerful applications where highest positioning and quickness accuracy is necessary. The flange result generates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. 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 provide same advantages as the GSB line; the right angle shape makes the GSBL collection an ideal match for all dynamic applications where space is limited.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-stage motors used in combination with a single-phase AC power and three-stage motors used in combination with a three-stage AC power. A single-phase motor could be operated by simply connecting it to a single-phase power via the supplied capacitor. A three-phase motor does not require a capacitor. All you have to is to connect the motor directly to a three-stage AC power supply.
The new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly suitable applications for the brand new range are those that place the highest demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines include precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
