The high-end economy lines GSN 
& GFE combine powerful with financial efficiency: both lines are also equipped 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 beat the competition for devices of the same size. All planetary carriers are produced as a cage created from solid material. This increases tranquil operating characteristics while at exactly the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water security in servo planetary gearbox accordance with protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The concentrate on manufacturing in precision gears is tighter tolerances, so all over the gear will be a tighter, more precise match. And the tighter fit means much less play in the gear teeth, which is the trigger of backlash in the first place. Of program, precision gears are more costly, if the application demands high accuracy, then precision gearing could be the way to go.
From a gear design perspective, a simple way to lessen backlash is to make sure the teeth mesh tightly together. That is typically done by shortening the guts distance between gears. As for pre-loading, this is often done using a spring mechanism to hold the gears firmly in place. This also eliminates the enjoy between the gear teeth and thus eliminates backlash.
Of course, the type of gears used can also have a huge impact on the quantity 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 ideals, the input stage is dimensionally smaller than the result stage. Its short design makes the GSD series the ideal high-end gearbox for space limited applications. The low standard backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and speed accuracy is required. The flange output 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 means high performance in combination with low backlash and high precision. Its robust, one-piece housing permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL collection provide same advantages as the GSB range; the right angle form makes the GSBL series an ideal match for all powerful 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-phase motors used with a single-phase AC power supply and three-phase 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 need a capacitor. All you need is for connecting the motor directly to a three-stage 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 appropriate applications for the brand new range are those which place the highest demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are created to meet the highest creation requirements – all lines are equipped with precision floor helical gearing, single-piece planetary carriers and full needle bearings.
