The high-end economy lines GSN & GFE combine powerful with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The entire needle bearing has been especially designed to reach high torques that defeat the competition for devices of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases quiet operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dust and splash water security in accordance with protection course IP65 in every lines.
One method to reduce worm drive servo china backlash is by using precision gears. The focus on production in precision gears is usually 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 course, precision gears are more expensive, if the application calls for high accuracy, then precision gearing may be the way to go.
From a gear design perspective, a simple way to lessen backlash is to ensure one’s teeth mesh tightly together. This is typically carried out by shortening the guts distance between gears. For pre-loading, this is often done utilizing a spring mechanism to carry the gears firmly set up. 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 amount of backlash. So for example, some equipment types such as strain 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 ideals, the input stage is definitely dimensionally smaller compared to the output stage. Its short style makes the GSD line the perfect 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 rate 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 higher. The GSB line means high performance in mixture 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 line offer the same advantages as the GSB range; the right angle form makes the GSBL range the perfect match for all dynamic applications where space is limited.

Incorrect tolerances, bearing misalignment, and manufacturing inconsistencies have a tendency to increase backlash.
AC motors and equipment 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. A single-phase motor can be operated by simply linking it to a single-phase power supply via the provided capacitor. A three-phase motor will not require 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 new range are those that 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 are equipped with precision surface helical gearing, single-piece planetary carriers and full needle bearings.
