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 provides been especially designed to reach high torques that defeat the competition for models of the same size. All planetary carriers are produced as a cage made from solid materials. This increases tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water protection in accordance with protection class IP65 in all lines.
One method to reduce backlash is by using precision gears. The focus on manufacturing in precision gears is usually tighter tolerances, so all over the gear is a tighter, more precise fit. And the tighter suit means less play in the gear teeth, which may be the cause of backlash to begin with. Of training course, precision gears are more costly, 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 ensure the teeth mesh tightly together. That is typically performed by shortening the guts distance between gears. As for pre-loading, this could be done using a spring mechanism to hold the gears firmly set up. This also eliminates the enjoy between the gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the quantity of backlash. So for example, some equipment types such as stress wave gears, or harmonic gear drives, have zero backlash.

The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, two-stage design. Because of the lower torque ideals, the input stage is dimensionally smaller compared to the result stage. Its short style makes the GSD line the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD collection makes it an ideal fit for highly dynamic applications where highest positioning and acceleration accuracy is necessary. The flange output generates highest torsional rigidity. For the accommodation of especially 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 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 range provide same advantages as the GSB range; the right angle shape makes the GSBL line 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 in combination with a single-stage AC power and three-stage motors used with a three-phase AC power. A single-phase motor could be operated by simply linking it to a single-phase power supply via the supplied capacitor. A three-phase motor will not need a capacitor. All you need is for connecting 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), Post Hole Digger Gearbox 1GSB (inline) and GSBL (angle gear) along with 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 zero backlash planetary gearbox china noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest production requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and full needle bearings.
