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 entire needle bearing has been especially designed to reach high torques that beat the competition for products of the same size. All planetary carriers are produced as a cage made from solid material. This increases noiseless operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water protection in accordance with protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on manufacturing in precision gears can be tighter tolerances, so all over the gear is a tighter, more precise fit. And the tighter suit means less play in the apparatus teeth, which may be the cause of backlash to begin with. Of training course, precision gears are more expensive, if the application demands high accuracy, then precision gearing may be the way to go.
From a equipment design perspective, an easy way to lessen backlash is to ensure the teeth mesh tightly together. That is typically completed by shortening the center distance between gears. For pre-loading, this can be done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the type of gears used can also have a huge impact on the amount of backlash. So for example, some gear types such as strain wave gears, or harmonic equipment drives, possess zero backlash.

The GSD, GSB & GSBL high-end servo planetary gearbox gearbox lines are constructed in a space-optimized, two-stage design. Due to the lower torque ideals, the input stage is definitely dimensionally smaller than the result stage. Its short design makes the GSD line the perfect high-end gearbox for space restricted applications. The low regular backlash of the GSD series makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange output produces highest torsional rigidity. For the lodging 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 permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB range; the right angle form makes the GSBL series the perfect match for all dynamic applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC motors and gear motors include single-stage motors used in combination with a single-stage AC power supply and three-phase motors used with a three-phase AC power. A single-phase motor could be operated by simply linking it to a single-phase power via the supplied capacitor. A three-phase motor does not need a capacitor. All you need is to connect the motor right 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 ideal applications for the new range are those that place the best demands on positioning accuracy, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and full needle bearings.
