The high-end economy lines GSN & GFE combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The full 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 made from solid material. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing band ensures maximum dust 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 certainly tighter tolerances, so all over the gear will be a tighter, more precise match. And the tighter suit means less play in the gear teeth, which is the trigger of backlash to begin with. Of training course, precision gears are more expensive, but if the application demands high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to make sure one’s teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. As for pre-loading, this can be done using a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used may also have a large impact on the amount of backlash. So for instance, some gear types such as stress wave gears, or harmonic equipment 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 ideals, the input stage is usually dimensionally smaller compared to the result stage. Its short design makes the GSD series the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD line 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 particularly high axial loads, taper roller bearings are optionally available 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 servo planetary gearbox housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line offer the same advantages as the GSB collection; the right angle form makes the GSBL line the perfect match for all powerful applications where space is bound.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC motors and gear motors include single-stage motors used with a single-phase AC power supply and three-phase 
motors used in combination with a three-phase 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 need a capacitor. All you need is for connecting the motor directly to a three-phase AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly appropriate applications for the brand new range are those that place the best demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest production requirements – all lines include precision surface helical gearing, single-piece planetary carriers and full needle bearings.
