zero backlash planetary gearbox

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 offers been especially designed to reach high torques that defeat the competition for units of the same size. All planetary carriers are zero backlash planetary gearbox manufactured as a cage created from solid materials. This increases tranquil operating characteristics while at the same time improving positioning precision and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security in accordance with protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is certainly tighter tolerances, so all around the gear is a tighter, more specific suit. And the tighter suit means much less play in the apparatus teeth, which may be the cause of backlash in the first place. Of course, precision gears are more expensive, but if the application calls for high accuracy, after that precision gearing could be the way to go.
From a gear design perspective, an easy way to reduce backlash is to ensure one’s teeth mesh tightly together. This is typically carried out 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 enjoy between your gear teeth and therefore eliminates backlash.
Of course, the type of gears used may also have a huge impact on the quantity of backlash. So for instance, 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. Because of the lower torque values, the input stage is dimensionally smaller compared to the output stage. Its short design makes the GSD series the ideal high-end gearbox for space restricted applications. The low standard backlash of the GSD line makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is required. The flange result produces highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective 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 higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection offer the same advantages as the GSB range; the right angle shape makes the GSBL range 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-phase motors used with a single-phase AC power and three-phase motors used in combination with a three-stage AC power supply. A single-phase motor could 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 need is to connect the motor directly to a three-phase AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) and also 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, working smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines are equipped with precision ground helical gearing, single-piece planetary carriers and complete needle bearings.
