The high-end economy lines GSN & GFE combine zero backlash planetary gearbox powerful with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing has been especially designed to reach high torques that beat the competition for units of the same size. All planetary carriers are produced as a cage created from solid materials. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water safety in accordance with protection course IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all around the gear is a tighter, more precise match. And the tighter suit means less play in the gear teeth, which is the cause of backlash in the first place. Of course, precision gears are more costly, but if the application calls for high accuracy, after that 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 center distance between gears. For pre-loading, this is often done using a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between your gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a large impact on the amount of backlash. So for instance, some gear 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. Due to the lower torque ideals, the input stage is dimensionally smaller compared to the result stage. Its short design makes the GSD line the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is required. The flange output generates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line means high performance in mixture with low backlash and high precision. Its robust, one-piece housing allows for a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB line; the right angle form makes the GSBL collection an ideal 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 equipment motors include single-phase motors used in combination with a single-stage AC power and three-stage motors used with a three-phase AC power. A single-phase motor can be operated by simply connecting it to a single-phase power via the supplied capacitor. A three-phase motor will not require a capacitor. All you need is for connecting the motor right to a three-stage AC power supply.
The new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) and also the high-end economy GSN and GFE lines. Particularly suitable applications for the brand new range are those which place the highest demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and full needle bearings.
