The high-end economy lines GSN & GFE combine high performance with economic efficiency: both lines are also built with helical ground gears, ensuring a minimum noise level and smooth running. The entire needle bearing has been especially designed to reach high torques that beat the competition for devices of the same size. All planetary carriers are manufactured as a cage made from solid materials. This increases calm operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing band ensures maximum dust and splash water safety relative to protection class IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is tighter tolerances, so all around the gear will be a tighter, more precise suit. And the tighter fit means much less play in the apparatus teeth, which is the cause of backlash to begin with. Of program, precision gears are more costly, if the application demands high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, a simple way to reduce backlash is to make sure the teeth mesh tightly together. That is typically completed by shortening the guts distance zero backlash planetary gearbox between gears. For pre-loading, this can be done using a spring mechanism to hold the gears firmly set up. This also eliminates the perform between your gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a huge impact on the amount of backlash. So for example, some equipment types such as stress 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 values, the input stage is definitely dimensionally smaller than the result stage. Its short style makes the GSD range the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD series makes it the perfect fit for highly dynamic applications where highest positioning and speed accuracy is required. The flange result creates highest torsional rigidity. For the accommodation of particularly high axial loads, taper roller bearings are optionally available in sizes with 90 mm diameter or more. The GSB line means high performance in combination 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 line offer the same advantages as the GSB collection; the right angle shape makes the GSBL series the perfect match for all dynamic applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies tend to increase backlash.
AC motors and equipment motors include single-phase motors used with a single-phase AC power supply and three-phase motors used in combination with a three-stage AC power supply. A single-phase motor can be operated by simply connecting it to a single-phase power via the supplied capacitor. A three-phase motor will not require 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 equipment), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly suitable applications for the new range are those which place the highest demands on positioning precision, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest production requirements – all lines include precision surface helical gearing, single-piece planetary carriers and full needle bearings.
