The high-end economy lines GSN & GFE combine high performance with economic 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 defeat the competition for units of the same size. All planetary carriers are produced as a cage created from solid materials. This increases tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing ring ensures maximum dust and splash water protection relative to protection course IP65 in every lines.
One way to reduce backlash is to use precision gears. The focus on production in precision gears is definitely tighter tolerances, so all around the gear will be a tighter, more precise fit. And the tighter match means much less play in the apparatus teeth, which is the cause of backlash in the first place. Of course, precision gears are more expensive, if the application demands high accuracy, after that precision gearing may be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to make sure the teeth mesh tightly together. That is typically carried out by shortening the guts distance between gears. For pre-loading, this can be done using a spring mechanism to carry the gears firmly in place. This also eliminates the play between your gear teeth and thus eliminates backlash.
Of course, the type of gears used can 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, have zero backlash.
The GSD, GSB & GSBL high-end gearbox lines are constructed in a space-optimized, zero backlash planetary gearbox china two-stage design. Due to the lower torque values, the input stage is dimensionally smaller compared to the output stage. Its short design makes the GSD range the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD range makes it an ideal fit for highly powerful applications where highest positioning and velocity accuracy is necessary. The flange result creates highest torsional rigidity. For the lodging 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 permits a higher gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL range offer the same advantages as the GSB collection; the right angle shape makes the GSBL collection 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-stage AC power supply and three-stage motors used in combination with a three-stage AC power. A single-phase motor can be operated by simply connecting it to a single-phase power via the provided capacitor. A three-phase motor does not need a capacitor. All you have to is to connect the motor right to a three-phase AC power supply.
The brand new planetary gearbox series includes the high-end gearbox lines GSD (flange equipment), GSB (inline) and GSBL (angle gear) along with the high-end economy GSN and GFE lines. Particularly ideal applications for the new range are those which place the highest demands on positioning accuracy, operating noises, running smoothness, bending rigidity and transmitted torque. The planetary gears are designed to meet the highest creation requirements – all lines include precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
