The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing provides been especially made to reach high torques that defeat the competition for systems of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dirt and splash water safety relative to protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears can be tighter tolerances, so all over the gear will be a tighter, more exact match. And the tighter fit means less play in the gear teeth, which may be the trigger of backlash to begin with. Of program, 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, an easy way to lessen backlash is to ensure one’s teeth mesh tightly together. That is typically completed by shortening the guts distance between gears. As for pre-loading, this can be done utilizing a spring mechanism to hold 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 may also have a large impact on the quantity of backlash. So for 
example, some equipment 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 certainly dimensionally smaller than the output stage. Its short design makes the GSD range the perfect high-end gearbox for space restricted applications. The low standard backlash of the GSD series makes it an ideal fit for highly dynamic applications where highest positioning and acceleration accuracy is required. The flange result zero backlash planetary gearbox creates 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 range offer the same advantages as the GSB series; the right angle form makes the GSBL range the perfect match for all powerful 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 with a single-phase AC power and three-stage motors used in combination with a three-phase AC power supply. A single-phase motor can be operated by simply connecting it to a single-phase power supply via the provided capacitor. A three-phase motor will not need a capacitor. All you have to 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) as well as the high-end economy GSN and GFE lines. Particularly appropriate applications for the new range are those that place the highest demands on positioning accuracy, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest production requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
