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 full needle bearing has been especially designed to reach high torques that defeat the competition for products of the same size. All planetary carriers are produced as a cage made from solid materials. This increases peaceful operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water protection in accordance with protection class IP65 in every lines.
One method to reduce backlash is by using precision gears. The concentrate on production in precision gears is tighter tolerances, so all around the gear will be a tighter, more specific suit. And the tighter suit means less play in the gear teeth, which may be the trigger of backlash to begin with. Of training course, precision gears are more expensive, but if the application demands 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 make sure the teeth mesh tightly together. This is typically performed by shortening the center distance between gears. As for pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly in place. This also eliminates the enjoy between the gear teeth and thus eliminates backlash.
Of course, the kind of gears used may also have a large impact on the quantity of backlash. So for example, some gear 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 definitely dimensionally smaller than the result stage. Its short design makes the GSD collection the perfect high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange output produces 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 stands for high performance in combination 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 collection provide same advantages as the GSB line; the right angle form 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-stage motors used in combination with a single-phase AC power supply and three-phase motors used in combination with a three-phase AC power supply. A single-phase motor can be operated by simply zero backlash planetary gearbox china connecting it to a single-phase power via the provided capacitor. A three-phase motor does not require a capacitor. All you need 
is for connecting the motor right to a three-phase AC power supply.
The 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 appropriate applications for the brand new range are those which place the best demands on positioning accuracy, 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 complete needle bearings.
