The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing offers been especially made to reach high torques that beat the competition for devices of the same size. All planetary carriers are produced as a cage created from solid materials. This increases peaceful operating characteristics while at the same time improving positioning precision and reducing backlash. An additional shaft sealing ring ensures maximum dirt and splash water safety relative to protection course IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is servo planetary gearbox definitely tighter tolerances, so all around the gear is a tighter, more precise match. And the tighter suit means less play in the apparatus teeth, which is the trigger of 
backlash to begin with. Of training course, precision gears are more costly, if the application demands high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, an easy way to reduce backlash is to make sure the teeth mesh tightly together. That is typically completed by shortening the center distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to hold the gears firmly in place. This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the type of gears used may 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, possess zero backlash.
The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Due to the lower torque values, the input stage is dimensionally smaller than the result stage. Its short style makes the GSD line the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD collection makes it the perfect fit for highly dynamic applications where highest positioning and quickness accuracy is required. The flange output generates 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 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 series; 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 tend to increase backlash.
AC motors and equipment motors include single-stage motors used in combination with a single-phase AC power and three-phase motors used in combination with a three-stage 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 will not need a capacitor. All you have to is to connect the motor directly to a three-stage AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) along with the high-end economy GSN and GFE lines. Particularly appropriate applications for the brand new range are those that place the highest demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines include precision floor helical gearing, single-piece planetary carriers and complete needle bearings.
