The high-end servo planetary gearbox economy lines GSN & GFE combine powerful with financial efficiency: both lines are also equipped with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing offers been especially designed to reach high torques that defeat the competition for units of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dirt and splash water safety relative to protection course IP65 in all lines.
One method to reduce backlash is to use precision gears. The focus on manufacturing in precision gears is definitely tighter tolerances, so all 
around the gear is a tighter, more precise fit. And the tighter match means much less play in the gear teeth, which is the cause of backlash to begin with. Of course, precision gears are more expensive, but if the application calls for high accuracy, after that precision gearing could be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. For pre-loading, this could be done utilizing a spring mechanism to carry the gears firmly set up. This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may also have a huge impact on the amount of backlash. So for example, some equipment types such as strain 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 ideals, the input stage can be dimensionally smaller compared to the result stage. Its short design makes the GSD range the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and acceleration accuracy is required. The flange output creates highest torsional rigidity. For the lodging of particularly high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or more. The GSB line stands for high performance in combination with low backlash and high precision. Its robust, one-piece housing permits a higher 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 line; the right angle shape makes the GSBL collection an ideal match for all powerful applications where space is bound.
Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and gear motors include single-phase motors used 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 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 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 brand new range are those which place the best demands on positioning precision, operating noises, working smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest production requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
