servo planetary gearbox

The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing provides 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 material. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water safety relative to protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The focus on manufacturing in precision gears can be tighter tolerances, so all servo planetary gearbox around the gear will be a tighter, more precise match. And the tighter match means less play in the gear teeth, which may be the cause of backlash to begin with. Of course, precision gears are more expensive, if the application demands high accuracy, after that precision gearing may be the way to go.
From a gear design perspective, an easy way to lessen backlash is to make sure the 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 the 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 example, some equipment types such as stress 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 than the result stage. Its short design makes the GSD line the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and rate accuracy is required. The flange output produces highest torsional rigidity. For the accommodation of particularly 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB range; the right angle form makes the GSBL series 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 gear motors include single-stage motors used with a single-stage AC power and three-stage motors used in combination with a three-stage AC power supply. A single-phase motor could be operated by simply connecting it to a single-phase power supply via the supplied capacitor. A three-phase motor does not need a capacitor. All you have to is to connect 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 suitable applications for the brand new range are those which place the highest demands on positioning accuracy, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest production requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and full needle bearings.
