The high-end economy lines GSN & GFE combine high performance with financial efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing provides been especially made to reach high torques that defeat the competition for units of the same size. All planetary carriers are manufactured as a cage created from solid material. This increases tranquil operating characteristics while at the same time improving positioning accuracy and reducing backlash. An additional shaft sealing band ensures maximum dust and splash water protection relative to protection class IP65 in all lines.
One way to reduce backlash is to use precision gears. The concentrate on production in precision gears is tighter tolerances, so all over the gear is a tighter, more precise suit. And the tighter fit means much less play in the apparatus teeth, which is the cause of backlash in the first place. Of training course, precision gears are more expensive, but if the application demands high accuracy, then precision gearing could be the way to go.
From a equipment design perspective, a simple way to lessen backlash is to ensure the teeth mesh tightly together. That is typically completed by shortening the guts distance between gears. As for pre-loading, this could be done using a spring mechanism to carry the gears firmly in place. This also eliminates the perform between your gear teeth and therefore eliminates backlash.
Of course, the kind of gears used can also have a large impact on the amount of backlash. So for instance, some gear types such as strain wave gears, or harmonic gear drives, have zero backlash.
The GSD, GSB & GSBL high-end zero backlash planetary gearbox gearbox lines are constructed in a space-optimized, two-stage design. Due to the lower torque values, the input stage is usually dimensionally smaller compared to the output stage. Its short style makes the GSD range the ideal high-end gearbox for space restricted applications. The low regular backlash of the GSD line makes it the perfect fit for highly powerful applications where highest positioning and swiftness accuracy is required. The flange output produces highest torsional rigidity. For the lodging of particularly 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 high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the GSB line; the right angle shape makes the GSBL collection 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-stage motors used in combination with a single-stage AC power and three-stage motors used with a three-stage AC power supply. A single-phase motor can be operated by simply linking it to a single-phase power via the supplied capacitor. A three-phase motor will not require 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 brand new range are those which place the best 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 include precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
