The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing has been especially made to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage made from solid materials. This increases noiseless operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water security in accordance with protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is tighter tolerances, so all over the gear will be a tighter, more precise suit. And the tighter suit means less play in the apparatus teeth, which may be the cause of backlash in the first place. Of training course, precision gears are more costly, if the application demands high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure one’s teeth mesh tightly together. That is typically done by shortening the guts distance between gears. For pre-loading, this could be done using a spring mechanism to hold the gears firmly in place. This also eliminates the play between the gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for instance, some gear 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. Due to the lower torque values, the input stage is certainly dimensionally smaller compared to the result stage. Its short style makes the GSD line the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it the perfect fit for highly dynamic applications where highest positioning and speed accuracy is necessary. The flange output produces highest torsional rigidity. For the accommodation of particularly 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 worm drive servo china absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the GSB line; the right angle form makes the GSBL series the perfect match for all powerful 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 with a single-phase AC power and three-phase motors used with a three-stage AC power. A single-phase motor can be operated by simply linking it to a single-phase power supply via the supplied capacitor. A three-phase motor will not need a capacitor. All you have to is to connect the motor directly to a three-phase AC power supply.
The 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 suitable applications for the new range are those which place the best demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines include precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
