The high-end economy lines GSN & GFE combine high performance 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 beat the competition for devices of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water safety relative to protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is certainly tighter tolerances, so all over the gear is a tighter, more precise fit. And the tighter fit means much less play in the apparatus teeth, which may be the trigger of backlash to begin with. Of program, 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, a simple way to lessen 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 utilizing a spring mechanism to carry 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 can also have a large 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. Because of the lower torque values, the input stage is certainly dimensionally smaller compared to the output stage. Its short style makes the GSD line the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD range makes it an ideal fit for highly dynamic applications where highest positioning and velocity accuracy is required. The flange result generates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are elective 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 higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL series provide same advantages as the GSB series; the right angle form makes the GSBL range an ideal match for all powerful applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC zero backlash planetary gearbox motors and gear motors include single-stage motors used in combination with a single-phase AC power supply and three-phase motors used in combination with a three-stage AC power. A single-phase motor can be operated by simply linking it to a single-phase power via the supplied capacitor. A three-phase motor will not need a capacitor. All you need 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) as well as the high-end economy GSN and GFE lines. Particularly ideal applications for the new range are those that place the best demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest production requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
